[[File:Makespace-laser-cutter.JPG|thumb|460px|right|Our LS6090 PRO Laser Cutter]]

= Summary =

We have two LS 6090 PRO Laser Cutters. Each has a working area of 900mm by 600mm, and is powered by a 60w CO2 Water Cooled Laser Tube that can engrave and cut through materials such as wood, plastic, card, leather, fabrics, up to about 10-15mm thick (note, it can not cut metal). The laser cut is approximately 0.15mm wide, and a job can take a few seconds through to tens of minutes depending on material thickness and design complexity.

We have dedicated PCs running LaserCut 5.3 software to import, prepare and download jobs to the Laser Cutter. It can import various formats, with DXF being the most commonly used, so various software packages can be used to create your designs.

Here are some examples of laser jobs we've run (please add a photo of yours any time you do a job!)

= Using the Laser Cutter =

The laser cutter is a great way to easily produce accurate and complex 2D forms in various materials, and can be designed for with limited experience in various drawing or CAD applications. At the same time, it is an expensive tool with real risk of injury and fire, so is very important you know how to use it to avoid damaging yourself and the machine. '''You must only use the laser cutter if you have been trained, and if you are ever in any doubt about something, please ask for assistance.'''

== Training ==

<div style="background:#FADADD; border:1px solid #FFC0CB; padding:5px">
<b>YOU CAN ONLY USE THE LASER CUTTER IF YOU HAVE BEEN TRAINED</b><br>
and have been added to the [[Equipment/Laser_Cutter/Training#Trained_Users|Trained Users]] list by one of the Owners
</div>

To get trained on the laser cutter and be added to the qualified user list, you will need to arrange for a training session with one of the Laser Cutter Owners.

If you'd like to arrange training, please see:
* [[Equipment/Laser_Cutter/Training|Laser Cutter Training]]

== Health and Safety ==

The laser cutter is a potentially dangerous piece of equipment which must only be operated by members who have received appropriate training and who take due care. The top things to always remember when using the laser cutter are:
* '''ONLY USE THE LASER CUTTER IF YOU ARE ON THE LIST OF TRAINED USERS'''
* '''NEVER LEAVE THE LASER CUTTER RUNNING UNATTENDED'''
* '''KNOW WHAT TO DO IF A FIRE BREAKS OUT'''
* '''NEVER CUT MATERIALS THAT YOU DON'T KNOW ARE SAFE'''

As a trained user, you should be very aware of the following risks and how to deal with them:

'''FIRE (under normal operation)''' - Cutting at the wrong speed or the wrong power can result in the material igniting
* You must watch the cutter at all times and be prepared to abort the job if problems occur
* Small flashes of flame that don't hang around for a fraction of a second are acceptable, but any more is rare and not acceptable
* If a fire does take, this is the process you should follow (from minor to major):
** Press "pause" (the same button you started the job with) - This will turn the laser off so no more heat enters, and assuming the flame goes out, you can press "start" for the job to continue where it left off
** Open the lid - With the job paused, you can open the lid to blow out the flame. Again, it is possible to re-close the lid and continue where you left off
** Move the material from under the laser head assuming safe to do so (so it doesn't damage the optics; alternatively send the laser to home/datum), and smother with a spare sheet of material or blow out
** Use the workshop CO2 extinguisher to extinguish the flame
* You should also make a note in the log if any of this happens with associated materials and settings so we can keep track of any particular materials/settings we should look at

'''FIRE (abnormal operation)''' - If the head gets stuck or something else goes wrong, ignition could happen much more suddenly or intensely
* You must watch the cutter at all times and be prepared to abort the job if problems occur
* If the head gets trapped (e.g. tomb-stoning of a piece, mechanical failure) or any other problem occurs that causes or could cause fire, this is the process you should follow:
** Hit the emergency stop
** Open the lid and move the material from under the laser head assuming safe to do so (so it doesn't damage the optics)
** Blow out, smother with a spare sheet of material, or use the CO2 extinguisher to extinguish the flame as appropriate
* Ensure a Maintainer looks at the machine before it is brought back in to action if it is not obvious what went wrong and all is ok
* You should also make a note in the log if any of this happens with associated materials and settings so we can keep track of any particular materials/settings we should look at

'''FUMES''' - The laser cutting process will release different smoke and fumes depending on the material.
* Never cut PVC or a material you are not sure is safe. When PVC is heated it releases chlorine gas, this mixes with the moisture in the air and the result is hydrochloric acid which is toxic to humans and corrosive to machines.
* Ensure the filter is on and the cutter lid stays closed for a while after a job to allow the fumes to clear.
* If you are feeling strange, think the fume build up is too much, or for any other reason you are unsure, stop the job.

'''TRAPPING''' - The head and bed of the cutter can be moved by the front panel menu or programs in the machines memory.
* Be careful when working inside the cutting area or with the lid open not to trap hands, hair, clothing or anything else.
* Always check the machine for unexpected items that may have fallen in before closing the lid.
* Do not attempt to climb into the machine!

'''LASER BURNS/LIGHT''' - A 60W laser can do real damage.
* The laser should be safe within the confines of the machine, and cut-off automatically when the lid is open (although this should not be relied upon). The top window is safe to look through during a job, but do not attempt to interfere with these windows or the laser or in any way invent some way to look at the laser.
* Do not tamper with the laser cutter, or any interlocks. All side panels of the laser should always be closed and locked whilst the machine is plugged in.
* Do not put metal in the laser cutter.

== Can I cut it? ==

If it's not on this list, the answer is "NO YOU CAN'T CUT IT AT MAKESPACE". Even if other people say it's ok. Bear in mind that we can't ventilate externally like other people can.

If it's something that isn't covered here, do ask on the forums and we'll look into it :)

*Woody things
** Wood: yes! (be careful of fire)
** Plywood: yes if it is "laser ply". Normal plywood has non-laser compatible glue
** MDF: no. Clogs up our filters and smells bad.
** LaserMDF: no. It produces perhaps 50% the gunk of MDF but still too much.
** Cork: yes, but it with a badly charred edge, and won't cut very deeply --- try cutting from the back of your sheet and using the cut to guide a craft knife / scalpel to make a neat cut through to the front.

*Plasticy things
** Acrylic / Perspex: yes!
** PVC/Vinyl: absolutely not. Produces chlorine.
** Silicone: we tried it with very limited success. A mm or two perhaps, anything else chars and doesn't cut.
** White Delrin/Acetal: yes with great care. Make sure filters running well. Don't open lid too quickly. Check for fumes and fire.
** Black Delrin/Acetal: no. contains carbon black which can be toxic.
** Teflon: no (it is toxic)
** Nylon: no (consult an owner)
** Polythene/polyethylene: no (consult an owner)
** Lexan/Polycarbonate: no (consult an owner)
** Polypropylene: yes just. You must clean the bed. It will cut up to about 2mm. It's not a great quality cut, but just about doable. Fire risk.
** GPPS / Polystyrene / HIPS in thin solid sheet form: maybe. ask owner to help. NO FOAM (it's highly flammable)

*Papery things
** Card/Paper: yes! (be careful of fire)
** Tissue: yes if super super really careful (be REALLY careful of fire, have emergency procedure in place before you start)

*Metally things
** Metal of any thickness doesn't cut. The surface can be engraved with a paint application. LMM6000 Surmark/Thermark has been tested and is suggested for use, but expensive. The owners suggest a speed of 800 and maximum power.

*Exotics
** Fibre glass: no (unknown resin, glass particles)
** Carbon Fibre: no
** Slate: engravable for good effect

== Instructions ==

To use the laser cutter, you must have been trained and have had your name added to the trained user list; these instructions are not a substitute for this training. See the training section to understand how you can become qualified to use the laser cutter.

Although not a requirement, it is recommended someone else trained is also present when using the laser cutter. Having two pairs of eyes helps avoid forgotten steps, allows for double checking, clarifications and discussions, and ensures a greater pool of experience is both present and being built up as the laser is used.

'''Power Up'''

Give the machine a quick visual check. Make sure that there is nothing left on the bed, the water reservoir of the chiller looks normal, and that the equipment has no obvious damage or signs of being out-of-action. If the bed looks like it has residue on it, give it a wipe with IPA and a cloth.

Turn on primary switch on the trunking marked 'Laser'. The air filter system to the right of the laser cutter should start as should the air pump and the chiller. It should power up, make a decent amount of noise, and the lights should indicate the filter is in good condition (i.e. no need for replacement).

Make sure the lid is closed. Turn on the laser using the key on the right hand side. The inspection lamp should come on, a satisfying hum start up, and the cutter go into doing its self-checks.

Before doing any job, the laser should be left to warm up for 4-5 mins. While the machine warms up, power on the adjacent PC and start the LaserCut application from the desktop. During this time the water temperature shown on the chiller should drop from ambient temperature to the usual setting of 18C.

'''LaserCut 5.3 tips'''
If you're stuck in "draw a box" mode, etc you can right click and hit "pick" to get your pointer back

'''Load your Design'''

The PC software has an import facility ('''file > import''') which seems to be happy taking AutoCAD 2004 DXF files and other formats. The workspace of the laser bed is represented as the workarea in the LaserCut software. If the import doesn't do what you want size-wise, you can select the whole image and then use the 'size' command from the drop down menu to set the dimension you want. Clicking on the three dots ... symbol will adjust the other axis in the same proportion (keeping the aspect ratio fixed). Selecting the 'centre on bed' option will locate your imported drawing on the centre of the machine's cutting bed.

'''Prep'''

Select all (mouse-drag around all, or ctrl-a) and Tools -> Unite Lines. You always want to do this. Without it, many things won't work (will take longer, you'll get gaps, it won't do inner-before-outer, etching areas won't work, etc).

Make sure all your design fits within the bed. Even in immediate (relative) mode, you still need to do this.

'''Assign Settings to Colours'''

Each part of your drawing that is assigned a different colour can have a different cut action assigned. Each colour will appear on the menu on the right hand side of the screen with numbers related to power and speed of the laser which will be used for the colour.

The main options are to Cut (line) or Engrave (raster fill). A marking on the material is a Cut. For each material and cutting depth required, a corresponding speed and power must be entered. The handbook provided with the machine gives suggested values for various materials but these should be considered as a starting point for a test. See the '''Power and Speed Settings''' section for our guidelines and experiences for these settings.

Parts are cut "inside out" within a colour, so if you have a hole cutout in a small piece you don't need to give this a separate colour.

'''Download to the Cutter'''

Your drawing will feature a blue dot which represents the starting point of the laser; this is by default on the top right corner (can be changed in the menu). In general, you will want to use "immediate" mode, which means this point represents wherever the laser is positioned when you start the job. You can also run the job in absolute mode by unchecking the box, making the job use absolute positioning on the workspace.

To download, select Download and Download Current; the download option will by default call the file on the laser cutter 'LASER'.

'''Set the Focus'''

Before each job, the focus needs to be checked and set by adjusting the height of the bed, and thus the work piece, from the lens. The critical dimension here is 41mm and several gauges made of perspex will be left around the machine. This gauge needs to be a fit between the top surface of the material you intend to cut and the white plastic 'flap' on the lens piece. The height of the table is adjusted using the UP and DOWN buttons. Failure to set the distance correctly will result in an out of focus laser and much bigger (but lower powered) cut line. Always ensure there is clearance between the material and laser head before the head moves.

'''Aligning and Testing the Job'''

The cutter's menu will show the most recent downloaded file highlighted. Pressing the 'test' button will make the head travel along the square maximum extends of the cuts. This shows you that you have the material in the right place, and you have enough of it! You can do this repeatedly, moving the work piece by hand or the laser head using the arrow keys (after hitting ESC), until you are confident you have things where you want them.

'''Cut the Job'''

When happy with the location of the material, close the lid and press 'start' to start the cutter. Watch the head and at least at first be prepared to press the 'stop' button immediately if you find you are burning massive holes in your work piece! This goes back to doing some tests on a sample of your material and making sure you are happy with the cut speeds and power you have selected. You should stay near the cutter at all times and be prepared to pause it or stop it in the event of fire.

<span style="color:red">'''DO NOT EVER LEAVE THE CUTTER UNATTENDED'''</span>

'''Finishing'''

The end of the job is signified by a beep. Waiting a few moments for the exhaust pump to clear any remaining smoke is a good idea, especially with wood, and will limit the build up of smells in the rest of the workshop. Remove your work piece, ensuring that all parts are cleared from the bed of the machine.

'''Power Down'''

The cutter is turned off using the key switch, then the air filtering system with the green rocker switch. Shut down the PC and double check that everything is left in a safe state for the next user.

'''Clean the bed of debris using the soft brush, then wipe down the bed using IPA and a cloth.'''

If you have been cutting particularly 'dirty' materials, most notable MDF and Ply which leave a sticky residue then you will need to use the course side of one of the oven pads and lots of 'elbow grease'. Residue on the bed can impact the next persons' job so please make the effort to clean up and leave the cutter as you would wish to find it.

Go away excited by what you can make and come back with lots more drawings!

== Power and Speed Settings ==

In due time we will try to build up a large sample stock of materials and record the values which work best. Here are the sample material tests we have so far:

<gallery>
File:Laser-schmoo-3mm-acrylic.JPG|3mm Acrylic
File:Laser-schmoo-10mm-acrylic.JPG|10mm Acrylic
File:Laser-schmoo-9mm-mdf.JPG|9mm MDF (note: do not cut MDF - see above!)
</gallery>

Settings to get you started:
*3mm Acrylic: Speed 12, Power 100, Corner power 100
*5mm Acrylic: Speed 6, Power 100, Corner power 100
*Acrylic shallow cut: Speed 30, power 50, corner power 50
*Etching acrylic: Speed 400, Power 50, Spacing 0.05

To make your own material test, a test grid can be downloaded here: [[Media:Test grid.zip]]

*3mm Delrin: Speed 10, Power 100, Corner power 100
*5mm Delrin: Speed 4, Power 100, Corner power 100
*6mm Delrin: speed 3, Power 100, Corner power 100

== Tips & Tricks ==

* If the laser cutter's user interface does not seem to respond/do what you want, hit "ESC" to return to 'normal mode'.
* The opaque white acrylic needs slightly stronger settings for surface cuts as they are not as visible as in the transparent acrylic (i.e., for similar effect you need a deeper cut). Otherwise seems to cut equivalently to transparent acrylics.
* If you want a tight fit of pieces or very accurate sizing, keep in mind that the laser beam has a width of just over 0.1 mm (maybe 0.11 or 0.12 mm). So all exterior cut lines should be offset by 0.05 mm; you can do this very easily in the LaserCutter Software with the "Offset" tool (units are in mm, so enter '0.05' and select 'Outer').
* The DXF file format stores values only (not values and units). The internal units in the LaserCutter are in mm. If you set your document's units to mm in the exporting CAD system it should work fine, but generally it is a good idea to have a piece of geometry of known length, e.g. a line 100mm long, or a box of known size around your design. This makes adjusting the scaling a lot easier.
* If you want to export a DXF from Inkscape (which is a great, free vector drawing package), then make sure you do "Object to path" from the Path menu for the whole object and then during the export stage, untick both options for type of export. Choose mm as your unit.
* There's now a page to help with Inkscape and our laser at [[Equipment/Laser_Cutter_Inkscape]]
* If the jog buttons (arrow keys moving the laser head around) are only moving the head in small single steps rather than moving it continuously, make sure that the jog step size is set to 0.0mm in the Jog Settings section of the menu.

=== Material Usage ===
You want to use as little material as possible to save money, we want you to use as little material as possible to reduce re-stocking burden and wastage.
There's a neat tool you can use for packing SVG files into small spaces, find it here: http://svgnest.com/

== Fixing up a job that went wrong ==

If you messed up a job and, for example, some cut lines weren't cut, you might try to run the job again after recolouring all of the lines except the ones that didn't cut. You can then deselect those lines for output in the Cut/Engrave window on the top right of the Lasercut Interface, and this will keep your positioning.

If your head has moved, you can try setting some lines to power 1, which should not cut anything, but allows you to see where the head is travelling.

== Fixing strange issues ==

''Jaws has a FAQ on the desktop of her PC, with more useful hints, tricks, and solutions.''

* Etching doesn't work
** Lines are not closed. LaserCut usually warns you about this. Ctrl-a to select all, then Tools->Unite Lines (0.001 should be fine).
** Two copies on top of each other. Copies on top of each other "cancel out" any etching. Delete one copy.
** Test with Menu->Laser->Simulate

* LaserCut will not download to the laser cutter
** Check laser cutter isn't in a paused state
** Restart LaserCut on the PC. (We've not had any usb issues nor needed to restart the laser since upgrading the PC summer 2014).

* Laser cuts things out 2+ times
** Check you don't have two copies loaded on top of each other
** Check it's not set to cut multiple times in LaserCut (this setting is right of the Cut/Engrave/Speed/Power settings)
** Check the laser front panel says "001" at the bottom. If not, press right arrow until the number is highlighted, then down to adjust back to 1, then press return.

* Laser will only cut at the top right of the bed
** Download again with Immediate Mode ticked
** On laser panel, press return (I think?) then right twice (should select the bottom left option), then press return (I think).

*You Hit Emergency stop
** E-M button needs twisting to re-activate
** If that fails - check the circuit breaker inside. From the back of the machine, you want to open the lower flap on the left side, which should be unlocked. Near to the back, there is a breaker board. Flip the flippy bit.

Equipment/Laser Cutter Inkscape

2018-02-08T13:04:32Z

Mat-c: added export notes

=Inkscape tricks=

A selection of hints to get the best out of Inkscape with our laser cutter. This applies to Inkscape 0.48.4.x and later, if you have an earlier version you should upgrade.

==Page and grid setup==

Set the default units (file->preferences) to mm. Then design everything in mm. These are preserved in dxf (choose mm as the units when saving) and you won't have to resize in the laser software.

At the same point you can create a grid, I use a 1cm grid with 1mm minor lines - select the ''''Grids'''' tab and click ''''New'''' to create a new rectangular grid, for the one I use set units to mm, spacing to 1 and major grid line every 10. I change the colours so I can see the major grid lines even when zoomed in fully.

Now save your document as "MyDefaultInkscapeDocument" and use it to start every project you work on :)

This is a (zipped) default inkscape document (mm as default and 1mm/1cm grid) [[File:DefaultInkscape01.zip]]

==Preferences setup==

Interface -> Grids. Set to origin 0, Spacing 1mm, major grid ever 10 (as above for the default document)

Behaviour -> Steps. This is a personal preference but I (Mat) prefer Arrow Keys Move By to 0.5mm. With a 1mm grid and 0.5mm nudging I get a 1mm grid with optional 0.5mm positioning. Inset/Outset I set to 0.075mm which matches half the laser cutter kerf.

==Version 0.91==

0.91 is latest and greatest. It very occasionally crashes (PC) compared to previous version (rock steady). Worth upgrading. Has newer image tracing options, but best of all, you can put formulae into its number boxes. So if your circle is as 0.543 mm and you want to move it right 1mm you can edit it to 0.543+1 mm and it sorts it all out for you. Also *2, /2, etc are handy for scaling.

==General hints==
Use fill and don't use stroke (turn it off each time you create a shape). Stroke paths show the thick outline, and this confuses the sizing and bounding box for laser cut things. Fill mode for shapes makes everything work better. For shapes with holes, make it show self intersections as holes. This is closest to what a laser cutter will do. Menu: Object -> Fill and Stroke. Right hand side, click the "Fill" tab. Click the icon second from the right, looks a bit like a heart with a hole in it.

==Grids==

By default Inkscape won't actually use the grid, the buttons on the far right allow you to enable snap (first button from the top), to bounding boxes (second from top and subsequent four) and path nodes (the next group down). If you're not getting the snapping behaviour you expect play with turning these on. When snapping to path points it'll use the point closest to your mouse when you're dragging, so it matters where on the path you click!

I find it easiest to get a sense of how big the piece is going to be if I set the page dimensions to those of the laser cutting bed, i.e. 900x600mm. You can do this from ''''File->Document Properties...'''' then entering a custom size, remember to change units to mm.

==Outline mode==

Inkscape can be put into outline mode, allowing you to see objects which have neither stroke nor fill. This is great because adding a stroke changes the dimensions of the object (slightly, but potentially enough to matter) and adding a fill makes it hard to see what you're doing. Select from ''''View->Display Mode->Outline''''. As an alternative a default fill with opacity of 10% works nicely when creating compound objects.
Turning off stroke for each shape achieves the same result (make sure you give it a fill colour so you can still see it...)

==Text on a path==

Easy to do, create a path, create some text and use the ''''Text->Put on Path'''' menu item. With the text selected you can use the letter and word spacing controls to get the text to completely fill the path (I needed this for the plaque as we wanted the lists of names to butt up to each end of the shape). At this point the text and the path are coupled together, so while you can move the text away if you delete or change the path it'll alter. To get outlines ready for the cutter select the text object and do ''''Path->Object to Path'''', you can then delete the original path object used to flow the text.

==Rounded rectangles==

If you try to use these the cutter will largely ignore them. Use the ''''Path->Object to Path'''' to convert them into a generic path before exporting. Same for all boxes and circles.

Alternatively, enable the "use ROBO-Master type of spline output" (an option during saving) if your version of Inkscape supports it.

==Dashed paths==

The laser won't pay any attention to stroke styles you set in Inkscape. Recent versions, however, include an extension under ''''Modify Path -> Convert to Dashes'''' which will render whatever stroke style you've selected.

==Engraving text==

Regular fonts used by Inkscape and everything else are outline fonts, that is to say they're defined as a filled shape. When used by the laser cutter the laser will cut the outline of the font, which looks great for large characters but often very badly (and slowly) for small typefaces. There's an extension at http://www.evilmadscientist.com/2011/hershey-text-an-inkscape-extension-for-engraving-fonts/ which allows for the use of engraving fonts where the font is defined in terms of the path used by the cutting tool rather than an outline.

Note - the version of the library at that link is broken with modern (0.48.4) versions of Inkscape, I've fixed the problem and uploaded a patched version to https://dl.dropboxusercontent.com/u/70831580/HersheyText.zip

==Exporting==

In the latest version of inkscape you have an option from ''''File->Save As'''' to save as ''''Desktop Cutting Plotter (AutoCAD DXF R14)''''. With the default options this seems to work perfectly with the laser, dimensions are preserved etc. (Default = nothing ticked. Ticking boxes is bad for exporting).

Note, 'default options' means export unit is set to mm.

V0.91 to V0.92: They change the internal size of their units, check carefully when you import between versions. If you go from 0.92 to 0.91, you'll need a known-size box (eg 100x100mm) in your document to check. I (Mat) have had problems with crashing and failing to export DXFs.

Circles do not import into LaserCut5.3 on the laser machines. Convert everything to a path before export. I (Mat) select the parts I want to export, ctrl-c, ctrl-n (open a new Inkscape), ctrl-v to paste it in. Then ctrl-a to select all, and Path->Object To Path to convert circles to beziers. ctrl-a and the readout at the bottom should say something like "25 objects selected of type path". If it says "of type path, circle" the circles won't import properly. Convert them to bezier and it will be fine.

[[Equipment|Equipment]] / Warco Mill

[[File:warco_mill.jpg|thumb|460px|right|Warco Mill]]

= Summary =

The Warco mill can be used to machine objects from a wide range of materials. Training is required before members use the equipment because it is easy for users to damage it, and serious injuries, or fatalities, are possible. The machine has a table 660 x 152mm that can move 37cm in the X direction, 15cm in the Y and 34cm in the Z direction.

== Owners ==
* Diana Probst
* Mat Cook
* Roger Smith

== Health and Safety ==
* Power supply to be disconnected when changing tools.
* All cutting tools to be kept in their holders until they are required.
* Waste material/offcuts to be kept clear of work area.
* Equipment will be checked for defects before each use to minimise the risk of possible electrical faults or fire.
* Carbon Dioxide extinguisher to be available for any electrical fires
* Eye protection to be worn when using the equipment.
* Risk assessment: https://docs.google.com/viewer?a=v&pid=forums&srcid=MDgwNzUyNzQ4MjA0NjE0MDY2NDIBMTU4NTI2NjEyMjIzOTU5MDkyODQBdmpubUpFanBkTklKATAuMQEBdjI

== Training ==

<div style="background:#FADADD; border:1px solid #FFC0CB; padding:5px">
<b>THE MILL CAN CAUSE SERIOUS INJURY. ONLY APPROVED OPERATORS ARE PERMITTED TO USE IT.</b><br>
</div>

To get the required training to become an approved operator please contact one of the owners.

The owners will help users make the best use of the mill but it must be emphasised that learning to take full advantage of all its capabilities takes months of practice. The owners have limited time so members will need to take responsibility for much of their own training. More details about the training can be found at

* [[Equipment/WarcoMill/Training|Mill Training]]

== Instructions ==

The feeds and speeds spreadsheet introduced in training is available [https://docs.google.com/spreadsheets/d/1rgAgFnwFIsTOK6a2bODYmkc9voaACjGkP0-nbXctfU0/edit?usp=sharing here].

== Tips & Tricks ==

Use a conventional milling cut to get the part to approximately the final size. With a conventional cut the cutting surface and the work piece are moved in opposite directions. A climbing cut is where the cutting surface and the work piece are moved in the same direction. It produces a better finish but puts extra strain on the cutting tool AND IS MORE LIKELY TO BITE, TAKE UP THE BACKLASH, BITE FURTHER AND BREAK THINGS. Therefore only use conventional (opposing directions) cutting. (Climb cuts are only to be used for very small finishing pass operations, usually not in steel, where tool biting is not a concern).

When drilling, start with a spotting drill (centre drill at a push) to make sure that the hole starts exactly centre. It is usually OK to drill to a depth of 3 to 4 diameters in a single pass (less with a centre drill). After that withdraw the drill every diameter of cutting depth to clear the swarf. Use cutting fluid beyond a depth of about 2 diameters (and always in steel). Be aware that halving the diameter of a drill reduces its strength 8 fold. Small drills break very easily and broken tools present a hazard and are exceptionally difficult to remove. Much much less pressure is needed to drill small diameter holes. Use just enough pressure to create long curly chips. Look up the appropriate rotation speed for the drill. The Warco cannot spin fast enough for drills below about 2mm.

== Maintenance ==

* Clean away all swarf at the end of a work session with a brush or vacuum. Do not blow because this can send chips where they can damage the machine. Bare hands are very easily injured by the sharp surfaces.

CE Certification

2016-04-03T22:30:35Z

Mat-c: reformatted

* First pass at writing this*

Notes from the cammakespace user group.

Mat-C

You can self certify, but you can't just tick it off and say "done" - it needs to be well documented and in many cases externally tested. There are very few things that are not CE covered. Simple items (that are not toys or safety critical) can be exempt - eg a comb. Kits are exempt (eg requires soldering iron to assemble).

Risks: Potential prosecution by the trading standards authority, increased liability if anything goes wrong with sales of your item, invalidation of insurance.

SteveW

http://www.emcfastpass.com/cert-ebook/ Is a decent start point. Lots covered, and you'll have a decent idea of what you do and don't need to do. Well worth the $32 imho.
(I have EMC chambers and test gear - but get my stuff tested and certified externally, although I'm starting to ponder self-certifying for the easy stuff)

Mark Mellors

My experience of CE marking (based on a couple of industrial products) is that you need to show the product is safe. That's all.

Like many legal requirements though, there are standard, accepted/assumed ways of proving it's safe that aren't necessarily intuitive to an outsider.
I think its generally accepted that your product is safe if you have a documented, reasonably robust risk assessment for the use case, an FMEA to show that the product doesn't become lethal if one component fails (there are various levels of acceptable risk/redundancy that probably don't apply to your product) and that you have documents to show you meet all the relevant safety standards for the technology/implementation/application. Typically that means the 'Product Directives' but there are many that could be applicable, have a look at: http://www.ce-marking.org/how-many-directives.html
Some of the directives can be met by showing compliance was 'designed in', such as meeting the necessary level of insulation or isolation. Others need to be demonstrated by testing, such as EMC or can be very involved. For one of the products I'm working on at the moment, the standards require you to life test or abuse/overload test about 30 complete products and some of the tests take weeks to complete.

Wayne

You can self certify but if its your first product its probably best to get an external expert to review your technical file. I can recommend someone I've used before.

By way of an example, have a look at the Micro:bit Declaration of Conformity: https://microbit0.blob.core.windows.net/pub/hkeghjes/declaration-of-conformity.pdf

The micro:bit didn't need to be classified as a toy, so for some info regarding what is a toy and toy safety please have a look at this: http://www.hobbycraft.co.uk/toy-safety

The 'Technical File' mentioned in the micro:bit DoC would include, amongst other things, the documentation showing the safety check results, the hobbycraft link has some info on what else would be in that Technical File.

This is me being captain obvious, but... The point in time at which you obtain a CE mark needs to be factored into your product budget. If you've already have gone thru certification then a change in the product design may, or may not, require 1 (or more) tests to be executed again, which is extra cost and introduces time delays.

Rob V

With no mains connection you would still have to comply with radiated emissions, immunity to radiation and immunity to ESD. (Applies only to (most) electrical/electronic stuff - MatC). EMC is self certified and complaint driven so if you're 100% certain that either you're fully compliant or nobody will ever complain about it, then you might choose to take no action (but I would never suggest that in a professional capacity!). For something a little more complex the only sensible approach is to test it at an EMC house, which will cost you around £500 for a half day pre-scan with a technican, and maybe two to three times that for a full test with report. This doesn't include electrical or mechanical safety, just EMC. The amount of safety testing depends entirely on the nature of the product. A kid's toy with a kitemark is a whole different ballgame to a musical greeting card.

Oh, also keep in mind that for emissions, if the product is normally used with something else, that something else needs to be in the test chamber as well. So if you make a USB keyboard, you need a PC in the chamber too. This only applies if the thing is physically connected - radio is OK. Of course, if you DO have a radio you also have to be compliant with the relevant band requirements for each licensing authority in which you'll ship. If you have only one radio and you use a pre-certified module you can avoid this.

If you do have a mains connection, whether direct or via a power adaptor, you also need to comply with conducted emissions and immunity as well as the appropriate safety standard which depends on the electrical class. This is when you'll discover that your Chinese imported "CE Marked" power supplies really aren't (compliant) and why so many products ship with massive after-thought ferrites on their power cable.

You'll need to meet different standards for different territories. You're unlikely to get a container past customs in the US without an FCC conformity declaration - even if you think your product is exempt. In most cases CE meets or exceeds other standards, and often you can get multiple reports from a test house for a little extra. A CE mark alone isn't good enough to ship into the US (FCC) or other non EC territories - you need their mark too.

Failure to comply is a non event if nobody (including customs) complains about your product. However if they do, first your stock gets impounded regardless of whether it's compliant. Then your product gets tested and if it's found to be non compliant you're in trouble. If it's then discovered that you haven't made reasonable efforts to establish compliance before shipping with a mark you're in quite serious trouble. Stock does get destroyed and very occasionally company directors go to prison (I'm sure it's the nice kind though).

I'd recommend DB Technology who are just north of Cottenham, aren't too expensive, know their stuff, but tend to be busy. http://www.dbtechnology.co.uk/

For larger or more obscure jobs, or when DB are booked up for months, I'd recommend York EMC, although they're not local (Bristol or Leeds).

Steve W

There's an EMC exemption for exactly this sort of thing (DC-only, no chance of radiating, no relevant susceptibility). I think that a
battery torch was the example given. You'll need to document that that's the route you've taken. Links in that ebook I pointed at
earlier. (But you were asking for more generic advice...)

Jonathan H

If you're trying to get a product certified might be worth contacting UL ( http://uk.ul.com/). Think they are one of main companies for certification. Their reps and are always at hardware startups events and they give a free a consultation which might give you the specific regulation details you need to conform to. (I can dig out their details if interested). I believe they are expensive but it might of use.

Full agreemenrt with Rob on DB-Tech for a local EMC/ESD (and soon RED) test house - I use them for all the stuff I manage, they are really helpful and their prices are better than many other labs.

= Training Cheatsheet =

The training structure and prompt sheet. Please note, this is used by the Laser Cutter Owners as a prompt to ensure training is executed in a consistent and complete fashion is included on this page; this does not constitute and is not a substitute for the training itself.

== Group Training ==

The group training introduction structure, suitable for 1-4 members at a time in a 1 hr session.

Introduction of main components
* Laser
* Cutting Mechanics
* Water Cooler System
* Filter
* PC
* Materials (what it can cut, supply)

Checks for everyone to do
* Check in use, looks ok
* Check water bath, temperature

Powering Up
* Turning on filter (Tick = ok, Warning = tell the owners, Cross = don't use it and tell the owners)
* Turning on Laser and warmup, what to do if doesn't power up
* Turning on PC and starting software

LaserCut Project walkthrough (using M+S+text keyring example)
* Package function, drawing, import file types
* Bed dimensions
* Paths, yellow dots, 'united' shapes
* Blue dot, Immediate mode
* Layers and colours
* Through cut, surface cut and engraving, speeds and strengths
* Various steps to build keyring design (shapes, text, uniting, layers, alignment, scaling, layers)
* Job ordering
* Saving
* Download as immediate, delete, download current

Laser Operation
* Lid
* Control panel, escape
* Moving head XY, indicator laser, datum
* Moving Z
* Focus
* Start position and test
* Start, pause and emergency stop function
* Do job, pause/open lid, restart

Laser Hazards
* Process and progression for normal operation failure (fire) - pause, open, move, CO2
* Process for abnormal operation failure (mechanical/jam) - emergency stop, open, move, CO2
* Ensure confident of process

Power Down
* Switch off laser
* Switch off filtration
* Clean any residue from the bed or bottom tray
* Close lid

== Individual Training Task ==

The individual task to get familiar, prompt questions and check understanding:

Task
* Make a personalised focus tool
* Square acrylic of appropriate size
* Member's name, "Focus Tool", keychain hole
* Should use full cut, surface cut, engrave
* Should demonstrate all steps, size, appropriate ordering, positioning

Steps
* Set individual to work, don't prompt but do answer questions (or pose if needed)
* Talk through design once done, question/check things etc
* Proceed to lasering (watch carefully all steps)
* Ask to stop job/restart, question escalation process

Assuming all ok:
* Get them to read the health and safety notes about operation and materials
* Add to the trained member list!

== Project Oversight ==

For next 2-3 projects, ensure member will find another more experienced trained user to support them (second pair of eyes)

[[File:Makespace-laser-cutter.JPG|thumb|460px|right|Our LS6090 PRO Laser Cutter]]

= Summary =

We have two LS 6090 PRO Laser Cutters. Each has a working area of 900mm by 600mm, and is powered by a 60w CO2 Water Cooled Laser Tube that can engrave and cut through materials such as wood, plastic, card, leather, fabrics, up to about 10-15mm thick (note, it can not cut metal). The laser cut is approximately 0.15mm wide, and a job can take a few seconds through to tens of minutes depending on material thickness and design complexity.

We have dedicated PCs running LaserCut 5.3 software to import, prepare and download jobs to the Laser Cutter. It can import various formats, with DXF being the most commonly used, so various software packages can be used to create your designs.

Here are some examples of laser jobs we've run (please add a photo of yours any time you do a job!)

= Using the Laser Cutter =

The laser cutter is a great way to easily produce accurate and complex 2D forms in various materials, and can be designed for with limited experience in various drawing or CAD applications. At the same time, it is an expensive tool with real risk of injury and fire, so is very important you know how to use it to avoid damaging yourself and the machine. '''You must only use the laser cutter if you have been trained, and if you are ever in any doubt about something, please ask for assistance.'''

== Owners ==

The Owners are those who have volunteered to be in charge of the laser cutter, organising maintenance, responding to technical issues and generally being a point of contact. The current Owners of the Laser Cutter are:

* [[User:Mat-C|Mat Cook]]
* [[User:DianaProbst|Diana Probst]]
* Owners who are a little less current, but may still be able to help:
** [[User:Simon|Simon Ford]]
** [[User:Barhamd|David Barham]]
** [[User:Nickcadsoftuk|Nick Johnson]]

== Trainers ==

The Trainers are those who have volunteered to teach others to use the laser cutter and to promote good working practice. The current Trainers for the Laser Cutter are:

* Brian Starkey
* [[User:stevancw|Stevan Wing]]
* [[User:Mat-C|Mat Cook]]

and have been added to the [[Equipment/Laser_Cutter/Training#Trained_Users|Trained Users]] list by one of the Owners
</div>

To get trained on the laser cutter and be added to the qualified user list, you will need to arrange for a training session with one of the Laser Cutter Owners.

If you'd like to arrange training, please see:
* [[Equipment/Laser_Cutter/Training|Laser Cutter Training]]

== Health and Safety ==

The laser cutter is a potentially dangerous piece of equipment which must only be operated by members who have received appropriate training and who take due care. The top things to always remember when using the laser cutter are:
* '''ONLY USE THE LASER CUTTER IF YOU ARE ON THE LIST OF TRAINED USERS'''
* '''NEVER LEAVE THE LASER CUTTER RUNNING UNATTENDED'''
* '''KNOW WHAT TO DO IF A FIRE BREAKS OUT'''
* '''NEVER CUT MATERIALS THAT YOU DON'T KNOW ARE SAFE'''

As a trained user, you should be very aware of the following risks and how to deal with them:

'''FIRE (under normal operation)''' - Cutting at the wrong speed or the wrong power can result in the material igniting
* You must watch the cutter at all times and be prepared to abort the job if problems occur
* Small flashes of flame that don't hang around for a fraction of a second are acceptable, but any more is rare and not acceptable
* If a fire does take, this is the process you should follow (from minor to major):
** Press "pause" (the same button you started the job with) - This will turn the laser off so no more heat enters, and assuming the flame goes out, you can press "start" for the job to continue where it left off
** Open the lid - With the job paused, you can open the lid to blow out the flame. Again, it is possible to re-close the lid and continue where you left off
** Move the material from under the laser head assuming safe to do so (so it doesn't damage the optics; alternatively send the laser to home/datum), and smother with a spare sheet of material or blow out
** Use the workshop CO2 extinguisher to extinguish the flame
* You should also make a note in the log if any of this happens with associated materials and settings so we can keep track of any particular materials/settings we should look at

'''FIRE (abnormal operation)''' - If the head gets stuck or something else goes wrong, ignition could happen much more suddenly or intensely
* You must watch the cutter at all times and be prepared to abort the job if problems occur
* If the head gets trapped (e.g. tomb-stoning of a piece, mechanical failure) or any other problem occurs that causes or could cause fire, this is the process you should follow:
** Hit the emergency stop
** Open the lid and move the material from under the laser head assuming safe to do so (so it doesn't damage the optics)
** Blow out, smother with a spare sheet of material, or use the CO2 extinguisher to extinguish the flame as appropriate
* Ensure a Maintainer looks at the machine before it is brought back in to action if it is not obvious what went wrong and all is ok
* You should also make a note in the log if any of this happens with associated materials and settings so we can keep track of any particular materials/settings we should look at

'''FUMES''' - The laser cutting process will release different smoke and fumes depending on the material.
* Never cut PVC or a material you are not sure is safe. When PVC is heated it releases chlorine gas, this mixes with the moisture in the air and the result is hydrochloric acid which is toxic to humans and corrosive to machines.
* Ensure the filter is on and the cutter lid stays closed for a while after a job to allow the fumes to clear.
* If you are feeling strange, think the fume build up is too much, or for any other reason you are unsure, stop the job.

'''TRAPPING''' - The head and bed of the cutter can be moved by the front panel menu or programs in the machines memory.
* Be careful when working inside the cutting area or with the lid open not to trap hands, hair, clothing or anything else.
* Always check the machine for unexpected items that may have fallen in before closing the lid.
* Do not attempt to climb into the machine!

'''LASER BURNS/LIGHT''' - A 60W laser can do real damage.
* The laser should be safe within the confines of the machine, and cut-off automatically when the lid is open (although this should not be relied upon). The top window is safe to look through during a job, but do not attempt to interfere with these windows or the laser or in any way invent some way to look at the laser.
* Do not tamper with the laser cutter, or any interlocks. All side panels of the laser should always be closed and locked whilst the machine is plugged in.
* Do not put metal in the laser cutter.

== Can I cut it? ==

If it's not on this list, the answer is "NO YOU CAN'T CUT IT AT MAKESPACE". Even if other people say it's ok. Bear in mind that we can't ventilate externally like other people can.

If it's something that isn't covered here, do ask on the forums and we'll look into it :)

*Woody things
** Wood: yes! (be careful of fire)
** Plywood: yes if it is "laser ply". Normal plywood has non-laser compatible glue
** MDF: no. Clogs up our filters and smells bad.
** LaserMDF: no. It produces perhaps 50% the gunk of MDF but still too much.
** Cork: yes. Let us know how it goes!

*Plasticy things
** Acrylic / Perspex: yes!
** PVC/Vinyl: absolutely not. Produces chlorine.
** Silicone: we tried it with very limited success. A mm or two perhaps, anything else chars and doesn't cut.
** White Delrin/Acetal: yes with great care. Make sure filters running well. Don't open lid too quickly. Check for fumes and fire.
** Black Delrin/Acetal: no. contains carbon black which can be toxic.
** Teflon: no (it is toxic)
** Nylon: no (consult an owner)
** Polythene/polyethylene: no (consult an owner)
** Lexan/Polycarbonate: no (consult an owner)
** Polypropylene: yes just. You must clean the bed. It will cut up to about 2mm. It's not a great quality cut, but just about doable. Fire risk.
** GPPS / Polystyrene / HIPS in thin solid sheet form: maybe. ask owner to help. NO FOAM (it's highly flammable)

*Papery things
** Card/Paper: yes! (be careful of fire)
** Tissue: yes if super super really careful (be REALLY careful of fire, have emergency procedure in place before you start)

*Metally things
** Metal of any thickness doesn't cut. The surface can be engraved with a paint application. LMM6000 Surmark/Thermark has been tested and is suggested for use, but expensive. The owners suggest a speed of 800 and maximum power.

*Exotics
** Fibre glass: no (unknown resin, glass particles)
** Carbon Fibre: no
** Slate: engravable for good effect

== Instructions ==

To use the laser cutter, you must have been trained and have had your name added to the trained user list; these instructions are not a substitute for this training. See the training section to understand how you can become qualified to use the laser cutter.

Although not a requirement, it is recommended someone else trained is also present when using the laser cutter. Having two pairs of eyes helps avoid forgotten steps, allows for double checking, clarifications and discussions, and ensures a greater pool of experience is both present and being built up as the laser is used.

'''Power Up'''

Give the machine a quick visual check. Make sure that there is nothing left on the bed, the water reservoir of the chiller looks normal, and that the equipment has no obvious damage or signs of being out-of-action. If the bed looks like it has residue on it, give it a wipe with IPA and a cloth.

Turn on primary switch on the trunking marked 'Laser'. The air filter system to the right of the laser cutter should start as should the air pump and the chiller. It should power up, make a decent amount of noise, and the lights should indicate the filter is in good condition (i.e. no need for replacement).

Make sure the lid is closed. Turn on the laser using the key on the right hand side. The inspection lamp should come on, a satisfying hum start up, and the cutter go into doing its self-checks.

Before doing any job, the laser should be left to warm up for 4-5 mins. While the machine warms up, power on the adjacent PC and start the LaserCut application from the desktop. During this time the water temperature shown on the chiller should drop from ambient temperature to the usual setting of 18C.

'''Load your Design'''

The PC software has an import facility ('''file > import''') which seems to be happy taking AutoCAD 2004 DXF files and other formats. The workspace of the laser bed is represented as the workarea in the LaserCut software. If the import doesn't do what you want size-wise, you can select the whole image and then use the 'size' command from the drop down menu to set the dimension you want. Clicking on the three dots ... symbol will adjust the other axis in the same proportion (keeping the aspect ratio fixed). Selecting the 'centre on bed' option will locate your imported drawing on the centre of the machine's cutting bed.

'''Assign Settings to Colours'''

Each part of your drawing that is assigned a different colour can have a different cut action assigned. Each colour will appear on the menu on the right hand side of the screen with numbers related to power and speed of the laser which will be used for the colour.

The main options are to Cut (line) or Engrave (raster fill). A marking on the material is a Cut. For each material and cutting depth required, a corresponding speed and power must be entered. The handbook provided with the machine gives suggested values for various materials but these should be considered as a starting point for a test. See the '''Power and Speed Settings''' section for our guidelines and experiences for these settings.

'''Download to the Cutter'''

Your drawing will feature a blue dot which represents the starting point of the laser; this is by default on the top right corner. In general, you will want to use "immediate" mode, which means this point represents wherever the laser is positioned when you start the job. You can also run the job in absolute mode by unchecking the box, making the job use absolute positioning on the workspace.

To download, select Download and Download Current; the download option will by default call the file on the laser cutter 'LASER'.

'''Set the Focus'''

Before each job, the focus needs to be checked and set by adjusting the height of the bed, and thus the work piece, from the lens. The critical dimension here is 41mm and several gauges made of perspex will be left around the machine. This gauge needs to be a fit between the top surface of the material you intend to cut and the white plastic 'flap' on the lens piece. The height of the table is adjusted using the UP and DOWN buttons. Failure to set the distance correctly will result in an out of focus laser and much bigger (but lower powered) cut line. Always ensure there is clearance between the material and laser head before the head moves.

'''Aligning and Testing the Job'''

The cutter's menu will show the most recent downloaded file highlighted. Pressing the 'test' button will make the head travel along the square maximum extends of the cuts. This shows you that you have the material in the right place, and you have enough of it! You can do this repeatedly, moving the work piece by hand or the laser head using the arrow keys (after hitting ESC), until you are confident you have things where you want them.

'''Cut the Job'''

When happy with the location of the material, close the lid and press 'start' to start the cutter. Watch the head and at least at first be prepared to press the 'stop' button immediately if you find you are burning massive holes in your work piece! This goes back to doing some tests on a sample of your material and making sure you are happy with the cut speeds and power you have selected. You should stay near the cutter at all times and be prepared to pause it or stop it in the event of fire.

<span style="color:red">'''DO NOT EVER LEAVE THE CUTTER UNATTENDED'''</span>

'''Finishing'''

The end of the job is signified by a beep. Waiting a few moments for the exhaust pump to clear any remaining smoke is a good idea, especially with wood, and will limit the build up of smells in the rest of the workshop. Remove your work piece, ensuring that all parts are cleared from the bed of the machine.

'''Power Down'''

The cutter is turned off using the key switch, then the air filtering system with the green rocker switch. Shut down the PC and double check that everything is left in a safe state for the next user.

'''Clean the bed of debris using the soft brush, then wipe down the bed using IPA and a cloth.'''

If you have been cutting particularly 'dirty' materials, most notable MDF and Ply which leave a sticky residue then you will need to use the course side of one of the oven pads and lots of 'elbow grease'. Residue on the bed can impact the next persons' job so please make the effort to clean up and leave the cutter as you would wish to find it.

Go away excited by what you can make and come back with lots more drawings!

== Power and Speed Settings ==

In due time we will try to build up a large sample stock of materials and record the values which work best. Here are the sample material tests we have so far:

<gallery>
File:Laser-schmoo-3mm-acrylic.JPG|3mm Acrylic
File:Laser-schmoo-10mm-acrylic.JPG|10mm Acrylic
File:Laser-schmoo-9mm-mdf.JPG|9mm MDF (note: do not cut MDF - see above!)
</gallery>

Settings to get you started:
*3mm Acrylic: Speed 12, Power 100, Corner power 100
*5mm Acrylic: Speed 6, Power 100, Corner power 100
*Acrylic shallow cut: Speed 30, power 50, corner power 50
*Etching acrylic: Speed 400, Power 50, Spacing 0.05

To make your own material test, a test grid can be downloaded here: [[Media:Test grid.zip]]

== Tips & Tricks ==

* If the laser cutter's user interface does not seem to respond/do what you want, hit "ESC" to return to 'normal mode'.
* The opaque white acrylic needs slightly stronger settings for surface cuts as they are not as visible as in the transparent acrylic (i.e., for similar effect you need a deeper cut). Otherwise seems to cut equivalently to transparent acrylics.
* If you want a tight fit of pieces or very accurate sizing, keep in mind that the laser beam has a width of just over 0.1 mm (maybe 0.11 or 0.12 mm). So all exterior cut lines should be offset by 0.05 mm; you can do this very easily in the LaserCutter Software with the "Offset" tool (units are in mm, so enter '0.05' and select 'Outer').
* The DXF file format stores values only (not values and units). The internal units in the LaserCutter are in mm. If you set your document's units to mm in the exporting CAD system it should work fine, but generally it is a good idea to have a piece of geometry of known length, e.g. a line 100mm long, or a box of known size around your design. This makes adjusting the scaling a lot easier.
* If you want to export a DXF from Inkscape (which is a great, free vector drawing package), then make sure you do "Object to path" from the Path menu for the whole object and then during the export stage, enable "use ROBO-Master type of spline output". This should make sure all the curves and so on work. NB: in some cases the "ROBO-Master" option actually makes curves not work, and it should be disabled; see this [https://wiki.nottinghack.org.uk/wiki/Laser_cutter/Inkscape Nottinghack page]
* There's now a page to help with Inkscape and our laser at [[Equipment/Laser_Cutter_Inkscape]]
* If the jog buttons (arrow keys moving the laser head around) are only moving the head in small single steps rather than moving it continuously, make sure that the jog step size is set to 0.0mm in the Jog Settings section of the menu.

=== Material Usage ===
You want to use as little material as possible to save money, we want you to use as little material as possible to reduce re-stocking burden and wastage.
There's a neat tool you can use for packing SVG files into small spaces, find it here: http://svgnest.com/

== Fixing up a job that went wrong ==

If you messed up a job and, for example, some cut lines weren't cut, you might try to run the job again after deleting all of the lines except the ones that didn't cut. This will work if the origin is in the same place but, depending on the design, it might not be once you delete some lines. To solve this problem, you can run the job with the power set to 1 for all your fix-up lines. This is so low that it will not even mark the material but will show you exactly where the lines will go when you run it again with the correct power settings. You can then line this up correctly before doing your fix-up. Perhaps even set the speed a little lower so you can tell the difference between travel and cut movements.

Alternatively, if you can, keep enough lines to ensure that the origin stays in the same place, then set these lines to power 1 if you don't need them.
Then you can run the job again and everything will be in exactly the same place, no adjustment needed. Alternatively, you could avoid deleting any lines and just set the unwanted lines to power 1. If you have lots of lines however, this might make the cutter spend lots of time doing nothing.

== Fixing strange issues ==

* Etching doesn't work
** Lines are not closed. LaserCut usually warns you about this. Ctrl-a to select all, then Tools->Unite Lines (0.001 should be fine).
** Two copies on top of each other. Copies on top of each other "cancel out" any etching. Delete one copy.
** Test with Menu->Laser->Simulate

* LaserCut will not download to the laser cutter
** Check laser cutter isn't in a paused state
** Restart LaserCut on the PC. (We've not had any usb issues nor needed to restart the laser since upgrading the PC summer 2014).

* Laser cuts things out 2+ times
** Check you don't have two copies loaded on top of each other
** Check it's not set to cut multiple times in LaserCut (this setting is right of the Cut/Engrave/Speed/Power settings)
** Check the laser front panel says "001" at the bottom. If not, press right arrow until the number is highlighted, then down to adjust back to 1, then press return.

* Laser will only cut at the top right of the bed
** Download again with Immediate Mode ticked
** On laser panel, press return (I think?) then right twice (should select the bottom left option), then press return (I think).

*You Hit Emergency stop
** E-M button needs twisting to re-activate
** If that fails - check the circuit breaker inside. From the back of the machine, you want to open the lower flap on the left side, which should be unlocked. Near to the back, there is a breaker board. Flip the flippy bit.

Mat-c: /* Preferences */

=Inkscape tricks=

A selection of hints to get the best out of Inkscape with our laser cutter. This applies to Inkscape 0.48.4.x and later, if you have an earlier version you should upgrade.

==Page and grid setup==

Set the default units (file->preferences) to mm. Then design everything in mm. These are preserved in dxf (choose mm as the units when saving) and you won't have to resize in the laser software.

At the same point you can create a grid, I use a 1cm grid with 1mm minor lines - select the ''''Grids'''' tab and click ''''New'''' to create a new rectangular grid, for the one I use set units to mm, spacing to 1 and major grid line every 10. I change the colours so I can see the major grid lines even when zoomed in fully.

Now save your document as "MyDefaultInkscapeDocument" and use it to start every project you work on :)

This is a (zipped) default inkscape document (mm as default and 1mm/1cm grid) [[File:DefaultInkscape01.zip]]

==Preferences setup==

Interface -> Grids. Set to origin 0, Spacing 1mm, major grid ever 10 (as above for the default document)

Behaviour -> Steps. This is a personal preference but I (Mat) prefer Arrow Keys Move By to 0.5mm. With a 1mm grid and 0.5mm nudging I get a 1mm grid with optional 0.5mm positioning. Inset/Outset I set to 0.075mm which matches half the laser cutter kerf.

==Version 0.91==

0.91 is latest and greatest. It very occasionally crashes (PC) compared to previous version (rock steady). Worth upgrading. Has newer image tracing options, but best of all, you can put formulae into its number boxes. So if your circle is as 0.543 mm and you want to move it right 1mm you can edit it to 0.543+1 mm and it sorts it all out for you. Also *2, /2, etc are handy for scaling.

==General hints==
Use fill and don't use stroke (turn it off each time you create a shape). Stroke paths show the thick outline, and this confuses the sizing and bounding box for laser cut things. Fill mode for shapes makes everything work better. For shapes with holes, make it show self intersections as holes. This is closest to what a laser cutter will do. Menu: Object -> Fill and Stroke. Right hand side, click the "Fill" tab. Click the icon second from the right, looks a bit like a heart with a hole in it.

==Grids==

By default Inkscape won't actually use the grid, the buttons on the far right allow you to enable snap (first button from the top), to bounding boxes (second from top and subsequent four) and path nodes (the next group down). If you're not getting the snapping behaviour you expect play with turning these on. When snapping to path points it'll use the point closest to your mouse when you're dragging, so it matters where on the path you click!

I find it easiest to get a sense of how big the piece is going to be if I set the page dimensions to those of the laser cutting bed, i.e. 900x600mm. You can do this from ''''File->Document Properties...'''' then entering a custom size, remember to change units to mm.

==Outline mode==

Inkscape can be put into outline mode, allowing you to see objects which have neither stroke nor fill. This is great because adding a stroke changes the dimensions of the object (slightly, but potentially enough to matter) and adding a fill makes it hard to see what you're doing. Select from ''''View->Display Mode->Outline''''. As an alternative a default fill with opacity of 10% works nicely when creating compound objects.
Turning off stroke for each shape achieves the same result (make sure you give it a fill colour so you can still see it...)

==Text on a path==

Easy to do, create a path, create some text and use the ''''Text->Put on Path'''' menu item. With the text selected you can use the letter and word spacing controls to get the text to completely fill the path (I needed this for the plaque as we wanted the lists of names to butt up to each end of the shape). At this point the text and the path are coupled together, so while you can move the text away if you delete or change the path it'll alter. To get outlines ready for the cutter select the text object and do ''''Path->Object to Path'''', you can then delete the original path object used to flow the text.

==Rounded rectangles==

If you try to use these the cutter will largely ignore them. Use the ''''Path->Object to Path'''' to convert them into a generic path before exporting. Same for all boxes and circles.

Alternatively, enable the "use ROBO-Master type of spline output" (an option during saving) if your version of Inkscape supports it.

==Dashed paths==

The laser won't pay any attention to stroke styles you set in Inkscape. Recent versions, however, include an extension under ''''Modify Path -> Convert to Dashes'''' which will render whatever stroke style you've selected.

==Engraving text==

Regular fonts used by Inkscape and everything else are outline fonts, that is to say they're defined as a filled shape. When used by the laser cutter the laser will cut the outline of the font, which looks great for large characters but often very badly (and slowly) for small typefaces. There's an extension at http://www.evilmadscientist.com/2011/hershey-text-an-inkscape-extension-for-engraving-fonts/ which allows for the use of engraving fonts where the font is defined in terms of the path used by the cutting tool rather than an outline.

Note - the version of the library at that link is broken with modern (0.48.4) versions of Inkscape, I've fixed the problem and uploaded a patched version to https://dl.dropboxusercontent.com/u/70831580/HersheyText.zip

==Exporting==

In the latest version of inkscape you have an option from ''''File->Save As'''' to save as ''''Desktop Cutting Plotter (AutoCAD DXF R14)''''. With the default options this seems to work perfectly with the laser, dimensions are preserved etc. If you don't have this option upgrade your version of inkscape, it appeared some point over the last month or two.

Note, 'default options' means export unit is set to mm.

Interface -> Grids. Set to origin 0, Spacing 1mm, major grid ever 10 (as above for the default document)

Behaviour -> Steps. This is a personal preference but I (Mat) prefer Arrow Keys Move By to 0.5mm. With a 1mm grid and 0.5mm nudging I get a 1mm grid with optional 0.5mm positioning. Inset/Outset I set to 0.075mm which matches half the laser cutter kerf.

==Version 0.91==

0.91 is latest and greatest. It very occasionally crashes (PC) compared to previous version (rock steady). Worth upgrading. Has newer image tracing options, but best of all, you can put formulae into its number boxes. So if your circle is as 0.543 mm and you want to move it right 1mm you can edit it to 0.543+1 mm and it sorts it all out for you. Also *2, /2, etc are handy for scaling.

==Preferences==

Find step and change it to something sensible like 0.5 mm. (Edit -> Preferences -> Behaviour -> Steps). Also change to inset/outset to 0.075 (ie half laser kerf). Now you have a 1mm grid and 0.5mm nudge increments. Shift-arrows give 5mm increments.

==General hints==
Use fill and don't use stroke (turn it off each time you create a shape). Stroke paths show the thick outline, and this confuses the sizing and bounding box for laser cut things. Fill mode for shapes makes everything work better. For shapes with holes, make it show self intersections as holes. This is closest to what a laser cutter will do. Menu: Object -> Fill and Stroke. Right hand side, click the "Fill" tab. Click the icon second from the right, looks a bit like a heart with a hole in it.

==Grids==

By default Inkscape won't actually use the grid, the buttons on the far right allow you to enable snap (first button from the top), to bounding boxes (second from top and subsequent four) and path nodes (the next group down). If you're not getting the snapping behaviour you expect play with turning these on. When snapping to path points it'll use the point closest to your mouse when you're dragging, so it matters where on the path you click!

I find it easiest to get a sense of how big the piece is going to be if I set the page dimensions to those of the laser cutting bed, i.e. 900x600mm. You can do this from ''''File->Document Properties...'''' then entering a custom size, remember to change units to mm.

==Outline mode==

Inkscape can be put into outline mode, allowing you to see objects which have neither stroke nor fill. This is great because adding a stroke changes the dimensions of the object (slightly, but potentially enough to matter) and adding a fill makes it hard to see what you're doing. Select from ''''View->Display Mode->Outline''''. As an alternative a default fill with opacity of 10% works nicely when creating compound objects.
Turning off stroke for each shape achieves the same result (make sure you give it a fill colour so you can still see it...)

==Text on a path==

Easy to do, create a path, create some text and use the ''''Text->Put on Path'''' menu item. With the text selected you can use the letter and word spacing controls to get the text to completely fill the path (I needed this for the plaque as we wanted the lists of names to butt up to each end of the shape). At this point the text and the path are coupled together, so while you can move the text away if you delete or change the path it'll alter. To get outlines ready for the cutter select the text object and do ''''Path->Object to Path'''', you can then delete the original path object used to flow the text.

==Rounded rectangles==

If you try to use these the cutter will largely ignore them. Use the ''''Path->Object to Path'''' to convert them into a generic path before exporting. Same for all boxes and circles.

Alternatively, enable the "use ROBO-Master type of spline output" (an option during saving) if your version of Inkscape supports it.

==Dashed paths==

The laser won't pay any attention to stroke styles you set in Inkscape. Recent versions, however, include an extension under ''''Modify Path -> Convert to Dashes'''' which will render whatever stroke style you've selected.

==Engraving text==

Regular fonts used by Inkscape and everything else are outline fonts, that is to say they're defined as a filled shape. When used by the laser cutter the laser will cut the outline of the font, which looks great for large characters but often very badly (and slowly) for small typefaces. There's an extension at http://www.evilmadscientist.com/2011/hershey-text-an-inkscape-extension-for-engraving-fonts/ which allows for the use of engraving fonts where the font is defined in terms of the path used by the cutting tool rather than an outline.

Note - the version of the library at that link is broken with modern (0.48.4) versions of Inkscape, I've fixed the problem and uploaded a patched version to https://dl.dropboxusercontent.com/u/70831580/HersheyText.zip

==Exporting==

In the latest version of inkscape you have an option from ''''File->Save As'''' to save as ''''Desktop Cutting Plotter (AutoCAD DXF R14)''''. With the default options this seems to work perfectly with the laser, dimensions are preserved etc. If you don't have this option upgrade your version of inkscape, it appeared some point over the last month or two.

Note, 'default options' means export unit is set to mm.

== Summary ==

A CNC router is a computer controlled shaping machine. These are related to the hand held router. Instead of hand held routing, the tool paths can be controlled via computer numerical control. It is a computer-controlled machine for cutting various hard materials, such as wood, composites, aluminum, steel, plastics, and foams. It is one of many kinds of tools that have CNC variants. A CNC router is very similar in concept to a CNC milling machine. The CNC router is controlled by a computer. Coordinates are uploaded into the machine controller from a separate CAD program

== Health and Safety ==

The CNC Router is a potentially dangerous piece of equipment which must only be operated by members who have received appropriate training and who take due care. The top things to always remember when using the CNC Router are:
* '''ONLY USE THE CNC ROUTER IF YOU ARE ON THE LIST OF TRAINED USERS'''
* '''NEVER LEAVE THE CNC ROUTER RUNNING UNATTENDED'''

As a trained user, you should be very aware of the following risks and how to deal with them:

'''FIRE''' - Cutting with the wrong settings could result in the material igniting.

'''TRAPPING''' - Stand clear of the machine while in motion.

'''DUST''' - Ensure extraction system is working.

'''NOISE''' - Ensure that you wear the correct PPE when working with the machine for prolonged periods.

== CNC Glossary ==

As with most new ventures into another profession or hobby, there is the need to learn a “new language” and its common abbreviations. We have introduced some of these in the description of the workflow process above. Here we’ll look at some in more detail. These are listed in alphabetical order.

=== 2D/2.5D/3D Toolpaths ===

Depending on the information source, the definitions of 2D, 2.5D and 3D can be quite vague and appear to overlap.

'''2D''' is simple horizontal cuts at a constant Z depth. For example, you cut out letter or a plaque shape to hang on the wall by moving the tool down to a specific depth and tracing the shape of the part you are cutting in 2D.

'''2.5D''' would be a little more complex than 2D as while the tool is cutting, the Z depth would be changing instead of staying constant. Typically this still uses 2D vector data to define the path but the way the tool moves in relation to the 2D data and its form will determine the shape that is cut. The most common example of 2.5D is VCarving. Although this cuts 2D vector shapes, the V-shaped tool “rides” on the edges of the vectors, so as it gets wider it cuts deeper and as the vector get closer together it will lift up in Z.

'''3D'''' These are toolpaths that like 2.5D toolpaths can move simultaneously in all 3 (X, Y and Z) axes however the shape they cut is described by following a 3D computer model and not vectors. They are typically cut with a Ball-Nose (round ended) tool. The tool will go back and forth across the 3D model following the contours of the part similar to an old fashioned copying or digitizing machine. The smoothness of the finished part depends on the Stepover setting in the toolpath as that determines how many times the tool will pass over the model. The size of the tool is also important as the software will only let it cut the detail that the end of the tool can fit into as it traces over the virtual surface. Examples of 3D toolpaths are 3D Rouging and 3D Finishing

=== 3-axis===

A 3-axis CNC machine is one that can move a router bit in the 3 primary directions, X, Y and Z. The image below show 3 views of a typical CNC setup and how the axes are referenced from each viewing direction.

=== CAD ===

CAD has been used as an abbreviation for both “Computer Aided Design” and “Computer Aided Drafting”. Now it has become a generic term in its own right that refers to a software program that can be used to create a 2D or 3D design.

=== CAM ===

When you discuss designing and preparing projects for your CNC machine, the follow-on side of CAD is CAM, which stands for ‘Computer Aided Manufacturing’ or ‘Computer Aided Machining’. This is the part of the process where the geometry developed during the CAD design process are now used to create the instructions that will move your CNC machine to ‘manufacture’ or machine the part.

=== Collet ===

The collet assembly is the component on a router or spindle that holds the router bit securely and consists of a precision collet and a collet nut. The collet is precisely sized to hold the router bit shank and the collet nut applies a compressive, friction fit as it is properly tightened onto the router or spindle shaft. It is very important to keep the collets clean and well maintained and depending on use, they must be periodically replaced.

=== Gantry ===

The gantry is the part of a CNC machine that typically has one of the horizontal axes running along it and also moves along the other horizontal axis to create the X and Y movement for the tool. The Z axis is also typically mounted on the gantry.

=== G-Code ===

This is a generic term for the code which is sent to the machine with the instructions telling it how to move. Or, to put it in our context, the file that is saved from the software using the Post Processor to format it for the CNC machine. In reality it’s a particular type of data that a lot of CNC’s use a variant of – so G-code is not necessarily interchangeable to different machines. The name comes from the fact that many of the codes within in start with a G. For example G01 specifies a Feed Rate move and G00 specifies a Rapid move etc.

=== Pass ===

When you have a toolpath that is too deep, too wide or a combination of both for the router bit to remove all the material at one time, the toolpath is broken up into multiple ‘Passes’ with each pass removing a part of the material.

When the toolpath is too deep, a Pass Depth (see entry below) value for the bit will be set and used to indicate the maximum Z depth the tool should cut on each Pass. The amount of material a tool can remove will be determined by the tooltype, size, material being cut and many other parameters. Tooling manufacturers typically offer recommendations for these values.

=== Post Processor ===

There are hundreds of different brands and models of CNC machines currently in use. When it comes to controlling them, many have a lot in common, but there can and will be differences. So, if you look at this as each machine speaks a slightly different language, there has to be a way for a single CAD/CAM program to speak to each machine and this is accomplished by using an “interpreter” called a Post Processor, also sometimes simply referred to as ‘pp’ or ‘post’.

For example, you design a project to cut an exact size circle out of a piece of material and calculate a toolpath to do that. When you actually save that toolpath so it can be used at your CNC machine, the correct Post Processor will ensure the instructions for cutting that circle are prepared correctly so your CNC machine can read and understand them and accurately cut the circle as you intended.

=== Router Bed or Machine Bed ===

The ‘bed’ identifies the part of a CNC machine where the material being machined is placed and held securely in position. For best results, the bed needs to be flat and sturdy. In most designs the bed is stationary; however there are exceptions to this where the bed moves to provide either the X or Y axis movement.

=== Sacrifice Sheet / Spoilboard ===

The spoilboard is normally a sacrificial sheet of material placed on top of the machine bed and is intended to be replaced as necessary. It protects the machine bed and allows frequent surfacing which will help to keep a truly flat surface to mount material and help maintain accuracy. This allows the stock material to be screwed down to it and the parts drilled and cut all the way through the material thickness.

=== Stepover ===

The Stepover setting found for most router bits allows you to control horizontal movement when machining areas wider than the router bit. Physically, stepover is the distance the center of the bit moves horizontally for each pass.

The Stepover is shown in the programs as both a physical distance (0.025” or 0.5mm for example) and as a percentage of bit diameter (6%, 8%, 50%, etc.). You can enter either value and the software will automatically calculate the other one for you. Typically most users refer to Stepover by its percentage value as it is a simple whole number and can easily be translated to other tool sizes for a particular task, for example when finishing setting the Stepover to be 10% of the ballnose tools diameter normally creates a reasonably finish surface.

=== Toolpath ===

A toolpath is the path created during the CAM part of your project design and represents the instructions your CNC machine will use to make the router bit move to duplicate what you have designed. In the software it is typically displayed as a set of lines which show a virtual picture of the path the tool tip will move along when the toolpath is run on the machine.

=== Vector ===

Vector is the word used to describe a 2D line, arc or curve. A vector can be used to describe almost any 2D shape.

[[Equipment/CNC_Router/Hand_Controller|Hand Controller Look-up Guide]]

===Setting the Z Origin Using the Z0 Sensor===
''A tool that has an extremely narrow tip may break when it touches the tool sensor depending on which tool is to be used.''

1. Secure the workpiece on the bed, and place the Z0 sensor at the place where you want to set the Z origin on the workpiece. Face the surface of the Z0 sensor without the magnet facing upward.

[[image:Mill_z0.PNG]]

2. Use the handset to move the tool to the position above the sensor.

3. On the handset press OK + 8(Z-0). The tool slowly descend until it contacts the sensor. When the tool rises and stops, the setting operation is complete.

Note: It is important the tool is electrically conductive from tip to shaft, and the sensor is clean. Failure to check will cause damage to the tool and sensor.

4. Remove the sensor from the workpiece to a location where it will not interfere with future cutting operations.

==Software==

The standard software is Vectric's line of CAM software:

===VCarvePro===

[[image:Vcarvepro.png]]

VCarve Pro provides a powerful but intuitive software solution for 2D design and calculation of 2D and 2.5D toolpaths for cutting parts on a CNC Router.

The software can import 2D designs from other programs but also includes a full set of drawing and editing tools with advanced layout options such as True-Shape Nesting. The toolpath options cover all typical 2D routing operations such as Profiling, Pocketing, Auto-Inlays and Drilling as well as 2.5D strategies such as V-Carving, Prism carving, Fluting and even a decorative Texturing strategy. Each toolpath includes appropriate options to customize the settings and provide a high level of control for different types of operation. In addition all toolpaths can be previewed to show just how the part will look when it is actually cut, this allows instant feedback to allow toolpaths to be further optimized.

===Cut3D===

[[image:Vectric-cut3d.jpg|266px]]

Cut3D is a dedicated toolpath engine for CNC machining 3D models that have been designed using a 3D CAD or Graphics design product such as AutoCAD, Rhino3D, 3D Studio etc. or scanned using a laser or touch probe device. Cut3D's exceptionally easy to use interface leads you step-by-step through the process of loading a model, setting the size, interactively placing tabs to hold the job in place, calculating single, double or four sided roughing and finishing toolpaths, previewing the results and finally saving the CNC code to run on your machine.

3D Models that are too large / thick to machine because of gantry height, cutter length or limited material thickness can be 'Sliced' into separate pieces. Each slice can then be machined and the complete job assembled.

'''Training Resources''': http://support.vectric.com/training-material/cut3d

===PhotoVCarve===

[[image:Vectric-photovcarve.gif|266px]]

PhotoVCarve creates lines of grooves that vary in width and depth to represent the detail in a photograph or image. The quality of the finished result is very dependant upon a high level of contrast between the material surface and the machined grooves. This information is very important to remember when cutting designs using the PhotoVCarve software.

PhotoVCarve machines dark areas in a photograph with wide groove and the lighter areas to have narrower ones. The software automatically calculates the toolpaths based on the cutter selected and maximum depth of groove required.

== Tooling ==

=== Router Bits ===

Router bits (or cutters) are the most common type of cutter, they have two or more vertical cutting edges. These are good general purpose cutters that can be found in most DIY shops. They are the same type that you would use in a manual hand held router.

<gallery>
File:WP_20130813_025.jpg
File:WP_20130813_025.jpg
File:WP_20130814_002.jpg
File:WP_20130814_003.jpg
</gallery>

It is important to notice that the cutters are on the edge of the body only, they do not extend to the centre of the cutter. This means the cutter CAN NOT BE USED AS A DRILL. An holes that are made by these sorts of cutters must be made by ramping the cutter to the correct depth in a sloping or spiral motion.

<div style="background:#FADADD; border:1px solid #FFC0CB; padding:5px">
<b>NEVER USE ROUTER BITS THAT HAVE BEARINGS.</b> These types of cutters are designed for manual routers where you can feel the feed back of the bearing in contact with the material being cut. A CNC device has no such feedback and will press the bearing into the material has hard as it can until something gives, i.e. the cutter breaks or much worse the spindle breaks. People found using these types of cutters on the CNC router will be BANNED! Just use the version without the bearing.

<gallery>
File:WP_20130813_018.jpg
</gallery>

The cutting edges should always be the lowest part of the cutter.
</div>

=== End mills ===

'''Up Cut and Down Cut'''

Router end mills have two variants, up cut (left) and down cut (right); there is a third type, compression, but they are quite rare.

<gallery>
File:WP_20130813_015.jpg
</gallery>

Most cutters are up cut, which have the cutting service on the top of the flutes and as they rotate lift the chips up and away from the material being cut.

Down cut cutters have the cutting edge on the bottom of the flutes and push chips down towards the material being cut. This has the advantage of pressing the material being cut into the bed of the machine; this is especially useful for thin plastics. The other advantage is the top surface shows far less breakout and splintering, this is a big advantage for materials like laminates.

On image on the left has been cut with an up-cut end mill and the image on the right a down-cut.

<gallery>
File:WP_20130813_005.jpg
File:WP_20130813_007.jpg
</gallery>

NOTE: There is a very big disadvantage to down cut end mills, and that is that they do not clear there chips effectively in blind holes. This means they need larger ramping moves to get to the correct cutting depth and if used in pockets without enough clearance, the friction can lead to burning or melting of the material being cut.

Another down side to down-cut cutters, is that when cutting pockets, the bottom surface will not be as clean as that made with an up-cut cutter, which will do a far better job of clearing the waste chips that rub between the cutter and the material with a down-cut.

== Stock Tooling ==

In order to keep a small stock of cutters for general use, the CNC Router needs to have a means of generating money. Because there is no material provided for use with the CNC Router there is no way to bring in any funds for such things. Therefore, we ask that if you use one of the communal cutters please put 50p into the CNC Router Honesty Box. This will go towards funding for replenishing stock and also for the replacement of the sacrificial bed once it gets worn out. Please email the list if a communal cutter is broken or missing, so that they can replace it with one from stock.

There will likely be 1 or two of each of the following cutters available for use, however please do not count on this being the case:

* 2.5mm square cutter - single flute
* 1/8" square cutter - single flute
* 1/8" ball cutter - 2 flute

* 6mm square cutter - 2 flute
* 6mm ball cutter - 2 flute

* engraver 0.2 30deg 1/8" 30mm length (8 of)
* engraver 0.8 30deg 1/8" 30mm length (2 of)

* 22mm 2 flute straight
* 90deg x 32mm VBit

== Feeds & Speeds ==

What are feeds and speeds? Why are they important?

[http://www.youtube.com/watch?v=ip2jm_6aUyk&feature=c4-overview&list=UUivA7_KLKWo43tFcCkFvydw Milling machine tutorial - cutter selection, speeds and feeds]

[http://en.wikipedia.org/wiki/Speeds_and_feeds Wikipedia - Speeds and feeds]

The phrase speeds and feeds (or feeds and speeds) refers to two separate velocities in machine tool practice, cutting speed and feed rate. They are often considered as a pair because of their combined effect on the cutting process. Each, however, can also be considered and analyzed in its own right.

Cutting speed (also called surface speed or simply speed) is the speed difference (relative velocity) between the cutting tool and the surface of the workpiece it is operating on. It is expressed in units of distance along the workpiece surface per unit of time, typically surface feet per minute (sfm) or meters per minute (m/min). Feed rate (also often styled as a solid compound, feedrate, or called simply feed) is the relative velocity at which the cutter is advanced along the workpiece; its vector is perpendicular to the vector of cutting speed. Feed rate units depend on the motion of the tool and workpiece; when the workpiece rotates (e.g., in turning and boring), the units are almost always distance per spindle revolution (inches per revolution [in/rev or ipr] or millimeters per revolution [mm/rev]). When the workpiece does not rotate (e.g., in milling), the units are typically distance per time (inches per minute [in/min or ipm] or millimeters per minute [mm/min]), although distance per revolution or per cutter tooth are also sometimes used.

== Tips & Tricks ==

= Maintenance =

The maintenance of the CNC Router is carried out by the Owners, with some basic maintenance being carried out by Users on every job.

== Maintenance Schedule ==
Every job
* Vacuum cutting dust from bed and around machine
* Sand down high points created on sacrificial bed by cutting/screwing

As required, by users
* Empty extraction bin
* check for blockages in manifold box where extraction pipes meet

Monthly
* Inspect extraction hoses for splits/ wear
* Clean and oil guide rails
* Check level, condition and flow of cooling water and replace as necessary
* Inspect sacrificial bed, re-skim or replace as required
* Inspect cable from pendent to router
* Inspect ER11 collet nut for wear
* Inspect auto levelling probe wire
* check collet set for wear/damage
* Check USB socket on pendent and USB memory stick for splits/damage

Annual
* Check nuts on lead screws for excessive backlash and adjust if required
* Inspect all covers/structure for signs of damage, cracks etc
* Check tightness (or even presence) of screws holding covers in place
* Check CNC electronics (and PC) cabinets for dust build up and vacuum out if required
* Check feet/supports are all taking load and that the structure is level/flat
* Check motor cables aren't wearing/cracking

== Maintenance Log ==

Installed on 9th May 2013.

3/7/13: Lower spindle clamp bolts replaced with longer stainless ones, holes through tapped as original ones had stripped.

== Maintenance Shopping List ==

* Cutters
* Sacrificial Bed (1.2m x 1.2m 12mm MDF)

= Becoming an Owner/Trainer =

Becoming an '''Owner''' of a piece of Makespace equipment means that you will be responsible for the maintenance, upkeep and H&S of that equipment. You will also be responsible for running inductions and keeping the information banks (Wiki/Forum/Google Groups) maintained.

A '''Trainer''' is responsible for running inductions only but will be required to understand how the machine works in order to pass on the relevant skills. A trainer will not be required to maintain the machine but would be expected to keep an eye on its status and report any issues if they develop (as would be expected of any user).

== Steps to becoming an Owner or Trainer ==

* Step 1: Contact a current Owner who will talk you through the various responsibilities. [http://wiki.makespace.org/Equipment/CNC_Router#Owners Owners] or Forum: [http://makespace.org/forum/viewtopic.php?f=20&t=89 here]
* Step 2: Sign up to a 'Train the Trainer Training' session on Meetup. It is likely one will need to be set up specially in order for you to sign up but the owner you spoke to should take care of this.
* Step 3: Complete the training to the satisfaction of the Owner/s running the sessions.
* Step 4: Have your name added to the Trainers list and set up your first solo induction session.
* Step 5: Once you are a Trainer you are eligible to become an Owner of the CNC Router. To become an Owner will simply require one further meeting with one of the current owners. This will simply be to walk through the requirements and techniques of maintaining the machine along with any other responsibilites. If the other owners are happy, you can add your name to the [http://wiki.makespace.org/Equipment/CNC_Router#Owners Owners] list.

== Train the Trainer Training ==

The first session will be fairly informal, with a look to getting more familiar with the machine and how it operates. We will walk through the Induction cheat-sheet (located on the Wiki) and discuss methods of giving attendees the information they need to use the CNC Router safely.

The follow up sessions will be arranged during the first session. The second session will include a brief look at the software, Meetup and a full dry-run induction. The third session will be an observed induction where you will be left to train 2 people (with input if necessary). Once complete you will be free to arrange as many induction sessions as you are happy to do. Although you wont be an owner of the CNC Router, if you would like to become one at this point please ask.

= Laser Cutter Training =

This page documents the process for being trained on the Laser Cutter, and the list of members who have completed that training.

== Summary ==

Training takes place in three main steps:
* Group Training of 1-4 members, going through the equipment and how to use it (~1hr)
* Individual Training Task, where an individual member is set a task to complete to prove and improve understanding (~30min each)
* Project Oversight, where more experienced users oversee the projects being undertaken when cutting (first 2-3 projects)

Training on the Laser Cutter is run by the Laser Cutter Owners. The Laser Cutter Owners are a group of people responsible for maintaining and training on the laser cutter, and hence have been trained to train, and trained to perform the weekly and monthly maintenance on the laser cutter.

== Booking ==

Sessions are advertised on '''http://meetup.makespace.org'''
* For discussing training, or requesting additional slots if needed, use the mailing list thread: [https://groups.google.com/d/topic/cammakespace/vNrS07zVuY0/discussion Training : Laser Cutter]

Notes:
* You can only be trained if you have your name allocated to a slot (groups will be restricted to four at a time, so please don't make up additional spaces)
* You must do the group and individual training on the same day

* Member's name, "Focus Tool", keychain hole
* Should use full cut, surface cut, engrave
* Should demonstrate all steps, size, appropriate ordering, positioning

Steps
* Set individual to work, don't prompt but do answer questions (or pose if needed)
* Talk through design once done, question/check things etc
* Proceed to lasering (watch carefully all steps)
* Ask to stop job/restart, question escalation process

Assuming all ok:
* Get them to read the health and safety notes about operation and materials
* Add to the trained member list!

= Laser Cutter Training =

This page documents the process for being trained on the Laser Cutter, and the list of members who have completed that training.

== Summary ==

Training takes place in three main steps:
* Group Training of 1-4 members, going through the equipment and how to use it (~1hr)
* Individual Training Task, where an individual member is set a task to complete to prove and improve understanding (~30min each)
* Project Oversight, where more experienced users oversee the projects being undertaken when cutting (first 2-3 projects)

Training on the Laser Cutter is run by the Laser Cutter Owners. The Laser Cutter Owners are a group of people responsible for maintaining and training on the laser cutter, and hence have been trained to train, and trained to perform the weekly and monthly maintenance on the laser cutter.

== Booking ==

Sessions are advertised on '''http://meetup.makespace.org'''
* For discussing training, or requesting additional slots if needed, use the mailing list thread: [https://groups.google.com/d/topic/cammakespace/vNrS07zVuY0/discussion Training : Laser Cutter]

Notes:
* You can only be trained if you have your name allocated to a slot (groups will be restricted to four at a time, so please don't make up additional spaces)
* You must do the group and individual training on the same day

= Training Cheatsheet =

The training structure and prompt sheet. Please note, this is used by the Laser Cutter Owners as a prompt to ensure training is executed in a consistent and complete fashion is included on this page; this does not constitute and is not a substitute for the training itself.

== Group Training ==

The group training introduction structure, suitable for 1-4 members at a time in a 1 hr session.

Introduction of main components
* Laser
* Cutting Mechanics
* Water Cooler System
* Filter
* PC
* Materials (what it can cut, supply)

Checks for everyone to do
* Check in use, looks ok
* Check water bath, temperature

Powering Up
* Turning on filter (Tick = ok, Warning = tell the owners, Cross = don't use it and tell the owners)
* Turning on Laser and warmup, what to do if doesn't power up
* Turning on PC and starting software

LaserCut Project walkthrough (using M+S+text keyring example)
* Package function, drawing, import file types
* Bed dimensions
* Paths, yellow dots, 'united' shapes
* Blue dot, Immediate mode
* Layers and colours
* Through cut, surface cut and engraving, speeds and strengths
* Various steps to build keyring design (shapes, text, uniting, layers, alignment, scaling, layers)
* Job ordering
* Saving
* Download as immediate, delete, download current

Laser Operation
* Lid
* Control panel, escape
* Moving head XY, indicator laser, datum
* Moving Z
* Focus
* Start position and test
* Start, pause and emergency stop function
* Do job, pause/open lid, restart

Laser Hazards
* Process and progression for normal operation failure (fire) - pause, open, move, CO2
* Process for abnormal operation failure (mechanical/jam) - emergency stop, open, move, CO2
* Ensure confident of process

Power Down
* Switch off laser
* Switch off filtration
* Clean any residue from the bed or bottom tray
* Close lid

== Individual Training Task ==

The individual task to get familiar, prompt questions and check understanding:

Task
* Make a personalised focus tool
* Square acrylic of appropriate size
* Member's name, "Focus Tool", keychain hole
* Should use full cut, surface cut, engrave
* Should demonstrate all steps, size, appropriate ordering, positioning

Steps
* Set individual to work, don't prompt but do answer questions (or pose if needed)
* Talk through design once done, question/check things etc
* Proceed to lasering (watch carefully all steps)
* Ask to stop job/restart, question escalation process

Assuming all ok:
* Get them to read the health and safety notes about operation and materials
* Add to the trained member list!

== Project Oversight ==

For next 2-3 projects, ensure member will find another more experienced trained user to support them (second pair of eyes)

[[File:Makespace-laser-cutter.JPG|thumb|460px|right|Our LS6090 PRO Laser Cutter]]

= Summary =

We have two LS 6090 PRO Laser Cutters. Each has a working area of 900mm by 600mm, and is powered by a 60w CO2 Water Cooled Laser Tube that can engrave and cut through materials such as wood, plastic, card, leather, fabrics, up to about 10-15mm thick (note, it can not cut metal). The laser cut is approximately 0.15mm wide, and a job can take a few seconds through to tens of minutes depending on material thickness and design complexity.

We have dedicated PCs running LaserCut 5.3 software to import, prepare and download jobs to the Laser Cutter. It can import various formats, with DXF being the most commonly used, so various software packages can be used to create your designs.

Here are some examples of laser jobs we've run (please add a photo of yours any time you do a job!)

= Using the Laser Cutter =

The laser cutter is a great way to easily produce accurate and complex 2D forms in various materials, and can be designed for with limited experience in various drawing or CAD applications. At the same time, it is an expensive tool with real risk of injury and fire, so is very important you know how to use it to avoid damaging yourself and the machine. '''You must only use the laser cutter if you have been trained, and if you are ever in any doubt about something, please ask for assistance.'''

== Owners ==

The Owners are those who have volunteered to be in charge of the laser cutter, organising maintenance, responding to technical issues and generally being a point of contact. The current Owners of the Laser Cutter are:

* [[User:Mat-C|Mat Cook]]
* [[User:DianaProbst|Diana Probst]]
* [[User:stevancw|Stevan Wing]]
* Owners who are a little less current, but may still be able to help:
** [[User:Simon|Simon Ford]]
** [[User:Barhamd|David Barham]]
** [[User:Nickcadsoftuk|Nick Johnson]]
** [[User:Tmonca|Toby Moncaster]]

== Trainers ==

The Trainers are those who have volunteered to teach others to use the laser cutter and to promote good working practice. The current Trainers for the Laser Cutter are:

* Brian Starkey
* [[User:stevancw|Stevan Wing]]
* [[User:Mat-C|Mat Cook]]
* [[User:robv|Rob Voisey]]

* Currently slightly less frequent trainers are:

== Training ==

<div style="background:#FADADD; border:1px solid #FFC0CB; padding:5px">
<b>YOU CAN ONLY USE THE LASER CUTTER IF YOU HAVE BEEN TRAINED</b><br>
and have been added to the [[Equipment/Laser_Cutter/Training#Trained_Users|Trained Users]] list by one of the Owners
</div>

To get trained on the laser cutter and be added to the qualified user list, you will need to arrange for a training session with one of the Laser Cutter Owners.

If you'd like to arrange training, please see:
* [[Equipment/Laser_Cutter/Training|Laser Cutter Training]]

== Health and Safety ==

The laser cutter is a potentially dangerous piece of equipment which must only be operated by members who have received appropriate training and who take due care. The top things to always remember when using the laser cutter are:
* '''ONLY USE THE LASER CUTTER IF YOU ARE ON THE LIST OF TRAINED USERS'''
* '''NEVER LEAVE THE LASER CUTTER RUNNING UNATTENDED'''
* '''KNOW WHAT TO DO IF A FIRE BREAKS OUT'''
* '''NEVER CUT MATERIALS THAT YOU DON'T KNOW ARE SAFE'''

As a trained user, you should be very aware of the following risks and how to deal with them:

'''FIRE (under normal operation)''' - Cutting at the wrong speed or the wrong power can result in the material igniting
* You must watch the cutter at all times and be prepared to abort the job if problems occur
* Small flashes of flame that don't hang around for a fraction of a second are acceptable, but any more is rare and not acceptable
* If a fire does take, this is the process you should follow (from minor to major):
** Press "pause" (the same button you started the job with) - This will turn the laser off so no more heat enters, and assuming the flame goes out, you can press "start" for the job to continue where it left off
** Open the lid - With the job paused, you can open the lid to blow out the flame. Again, it is possible to re-close the lid and continue where you left off
** Move the material from under the laser head assuming safe to do so (so it doesn't damage the optics; alternatively send the laser to home/datum), and smother with a spare sheet of material or blow out
** Use the workshop CO2 extinguisher to extinguish the flame
* You should also make a note in the log if any of this happens with associated materials and settings so we can keep track of any particular materials/settings we should look at

'''FIRE (abnormal operation)''' - If the head gets stuck or something else goes wrong, ignition could happen much more suddenly or intensely
* You must watch the cutter at all times and be prepared to abort the job if problems occur
* If the head gets trapped (e.g. tomb-stoning of a piece, mechanical failure) or any other problem occurs that causes or could cause fire, this is the process you should follow:
** Hit the emergency stop
** Open the lid and move the material from under the laser head assuming safe to do so (so it doesn't damage the optics)
** Blow out, smother with a spare sheet of material, or use the CO2 extinguisher to extinguish the flame as appropriate
* Ensure a Maintainer looks at the machine before it is brought back in to action if it is not obvious what went wrong and all is ok
* You should also make a note in the log if any of this happens with associated materials and settings so we can keep track of any particular materials/settings we should look at

'''FUMES''' - The laser cutting process will release different smoke and fumes depending on the material.
* Never cut PVC or a material you are not sure is safe. When PVC is heated it releases chlorine gas, this mixes with the moisture in the air and the result is hydrochloric acid which is toxic to humans and corrosive to machines.
* Ensure the filter is on and the cutter lid stays closed for a while after a job to allow the fumes to clear.
* If you are feeling strange, think the fume build up is too much, or for any other reason you are unsure, stop the job.

'''TRAPPING''' - The head and bed of the cutter can be moved by the front panel menu or programs in the machines memory.
* Be careful when working inside the cutting area or with the lid open not to trap hands, hair, clothing or anything else.
* Always check the machine for unexpected items that may have fallen in before closing the lid.
* Do not attempt to climb into the machine!

'''LASER BURNS/LIGHT''' - A 60W laser can do real damage.
* The laser should be safe within the confines of the machine, and cut-off automatically when the lid is open (although this should not be relied upon). The top window is safe to look through during a job, but do not attempt to interfere with these windows or the laser or in any way invent some way to look at the laser.
* Do not tamper with the laser cutter, or any interlocks. All side panels of the laser should always be closed and locked whilst the machine is plugged in.
* Do not put metal in the laser cutter.

== Can I cut it? ==

If it's not on this list, the answer is "NO YOU CAN'T CUT IT AT MAKESPACE". Even if other people say it's ok. Bear in mind that we can't ventilate externally like other people can.

If it's something that isn't covered here, do ask on the forums and we'll look into it :)

*Woody things
** Wood: yes! (be careful of fire)
** Plywood: yes if it is "laser ply". Normal plywood has non-laser compatible glue
** MDF: no. Clogs up our filters and smells bad.
** LaserMDF: no. It produces perhaps 50% the gunk of MDF but still too much.
** Cork: yes. Let us know how it goes!

*Plasticy things
** Acrylic / Perspex: yes!
** PVC/Vinyl: absolutely not. Produces chlorine.
** Silicone: we tried it with very limited success. A mm or two perhaps, anything else chars and doesn't cut.
** White Delrin/Acetal: yes with great care. Make sure filters running well. Don't open lid too quickly. Check for fumes and fire.
** Black Delrin/Acetal: no. contains carbon black which can be toxic.
** Teflon: no (it is toxic)
** Nylon: no (consult an owner)
** Polythene/polyethylene: no (consult an owner)
** Lexan/Polycarbonate: no (consult an owner)
** Polypropylene: yes just. You must clean the bed. It will cut up to about 2mm. It's not a great quality cut, but just about doable. Fire risk.
** GPPS / Polystyrene / HIPS in thin solid sheet form: maybe. ask owner to help. NO FOAM (it's highly flammable)

*Papery things
** Card/Paper: yes! (be careful of fire)
** Tissue: yes if super super really careful (be REALLY careful of fire, have emergency procedure in place before you start)

*Metally things
** Metal of any thickness doesn't cut. The surface can be engraved with a paint application. LMM6000 Surmark/Thermark has been tested and is suggested for use, but expensive. The owners suggest a speed of 800 and maximum power.

*Exotics
** Fibre glass: no (unknown resin, glass particles)
** Carbon Fibre: no
** Slate: engravable for good effect

Good list of info here: http://inventionstudio.gatech.edu/wiki/Laser_cutter

== Instructions ==

To use the laser cutter, you must have been trained and have had your name added to the trained user list; these instructions are not a substitute for this training. See the training section to understand how you can become qualified to use the laser cutter.

Although not a requirement, it is recommended someone else trained is also present when using the laser cutter. Having two pairs of eyes helps avoid forgotten steps, allows for double checking, clarifications and discussions, and ensures a greater pool of experience is both present and being built up as the laser is used.

'''Power Up'''

Give the machine a quick visual check. Make sure that there is nothing left on the bed, the water reservoir of the chiller looks normal, and that the equipment has no obvious damage or signs of being out-of-action. If the bed looks like it has residue on it, give it a wipe with IPA and a cloth.

Turn on primary switch on the trunking marked 'Laser'. The air filter system to the right of the laser cutter should start as should the air pump and the chiller. It should power up, make a decent amount of noise, and the lights should indicate the filter is in good condition (i.e. no need for replacement).

Make sure the lid is closed. Turn on the laser using the key on the right hand side. The inspection lamp should come on, a satisfying hum start up, and the cutter go into doing its self-checks.

Before doing any job, the laser should be left to warm up for 4-5 mins. While the machine warms up, power on the adjacent PC and start the LaserCut application from the desktop. During this time the water temperature shown on the chiller should drop from ambient temperature to the usual setting of 18C.

'''Load your Design'''

The PC software has an import facility which seems to be happy taking AutoCAD 2004 DXF files and other formats. The workspace of the laser bed is represented as the workarea in the LaserCut software. If the import doesn't do what you want size-wise, you can select the whole image and then use the 'size' command from the drop down menu to set the dimension you want. Clicking on the three dots ... symbol will adjust the other axis in the same proportion (keeping the aspect ratio fixed). Selecting the 'centre on bed' option will locate your imported drawing on the centre of the machine's cutting bed.

'''Assign Settings to Colours'''

Each part of your drawing that is assigned a different colour can have a different cut action assigned. Each colour will appear on the menu on the right hand side of the screen with numbers related to power and speed of the laser which will be used for the colour.

The main options are to Cut (line) or Engrave (raster fill). A marking on the material is a Cut. For each material and cutting depth required, a corresponding speed and power must be entered. The handbook provided with the machine gives suggested values for various materials but these should be considered as a starting point for a test. See the '''Power and Speed Settings''' section for our guidelines and experiences for these settings.

'''Download to the Cutter'''

Your drawing will feature a blue dot which represents the starting point of the laser; this is by default on the top right corner. In general, you will want to use "immediate" mode, which means this point represents wherever the laser is positioned when you start the job. You can also run the job in absolute mode by unchecking the box, making the job use absolute positioning on the workspace.

To download, select Download and Download Current; the download option will by default call the file on the laser cutter 'LASER'.

'''Set the Focus'''

Before each job, the focus needs to be checked and set by adjusting the height of the bed, and thus the work piece, from the lens. The critical dimension here is 41mm and several gauges made of perspex will be left around the machine. This gauge needs to be a fit between the top surface of the material you intend to cut and the white plastic 'flap' on the lens piece. The height of the table is adjusted using the UP and DOWN buttons. Failure to set the distance correctly will result in an out of focus laser and much bigger (but lower powered) cut line. Always ensure there is clearance between the material and laser head before the head moves.

'''Aligning and Testing the Job'''

The cutter's menu will show the most recent downloaded file highlighted. Pressing the 'test' button will make the head travel along the square maximum extends of the cuts. This shows you that you have the material in the right place, and you have enough of it! You can do this repeatedly, moving the work piece by hand or the laser head using the arrow keys (after hitting ESC), until you are confident you have things where you want them.

'''Cut the Job'''

When happy with the location of the material, close the lid and press 'start' to start the cutter. Watch the head and at least at first be prepared to press the 'stop' button immediately if you find you are burning massive holes in your work piece! This goes back to doing some tests on a sample of your material and making sure you are happy with the cut speeds and power you have selected. You should stay near the cutter at all times and be prepared to pause it or stop it in the event of fire.

<span style="color:red">'''DO NOT EVER LEAVE THE CUTTER UNATTENDED'''</span>

'''Finishing'''

The end of the job is signified by a beep. Waiting a few moments for the exhaust pump to clear any remaining smoke is a good idea, especially with wood, and will limit the build up of smells in the rest of the workshop. Remove your work piece, ensuring that all parts are cleared from the bed of the machine.

'''Power Down'''

The cutter is turned off using the key switch, then the air filtering system with the green rocker switch. Shut down the PC and double check that everything is left in a safe state for the next user.

'''Clean the bed of debris using the soft brush, then wipe down the bed using IPA and a cloth.'''

If you have been cutting particularly 'dirty' materials, most notable MDF and Ply which leave a sticky residue then you will need to use the course side of one of the oven pads and lots of 'elbow grease'. Residue on the bed can impact the next persons' job so please make the effort to clean up and leave the cutter as you would wish to find it.

Go away excited by what you can make and come back with lots more drawings!

== Power and Speed Settings ==

In due time we will try to build up a large sample stock of materials and record the values which work best. Here are the sample material tests we have so far:

<gallery>
File:Laser-schmoo-3mm-acrylic.JPG|3mm Acrylic
File:Laser-schmoo-10mm-acrylic.JPG|10mm Acrylic
File:Laser-schmoo-9mm-mdf.JPG|9mm MDF (note: do not cut MDF - see above!)
</gallery>

Settings to get you started:
*3mm Acrylic: Speed 12, Power 100, Corner power 100
*5mm Acrylic: Speed 6, Power 100, Corner power 100
*Acrylic shallow cut: Speed 30, power 50, corner power 50
*Etching acrylic: Speed 400, Power 50, Spacing 0.05

To make your own material test, a test grid can be downloaded here: [[Media:Test grid.zip]]

== Tips & Tricks ==

* If the laser cutter's user interface does not seem to respond/do what you want, hit "ESC" to return to 'normal mode'.
* The opaque white acrylic needs slightly stronger settings for surface cuts as they are not as visible as in the transparent acrylic (i.e., for similar effect you need a deeper cut). Otherwise seems to cut equivalently to transparent acrylics.
* If you want a tight fit of pieces or very accurate sizing, keep in mind that the laser beam has a width of just over 0.1 mm (maybe 0.11 or 0.12 mm). So all exterior cut lines should be offset by 0.05 mm; you can do this very easily in the LaserCutter Software with the "Offset" tool (units are in mm, so enter '0.05' and select 'Outer').
* The DXF file format stores values only (not values and units). The internal units in the LaserCutter are in mm. If you set your document's units to mm in the exporting CAD system it should work fine, but generally it is a good idea to have a piece of geometry of known length, e.g. a line 100mm long, or a box of known size around your design. This makes adjusting the scaling a lot easier.
* If you want to export a DXF from Inkscape (which is a great, free vector drawing package), then make sure you do "Object to path" from the Path menu for the whole object and then during the export stage, enable "use ROBO-Master type of spline output". This should make sure all the curves and so on work. NB: in some cases the "ROBO-Master" option actually makes curves not work, and it should be disabled; see this [https://wiki.nottinghack.org.uk/wiki/Laser_cutter/Inkscape Nottinghack page]
* There's now a page to help with Inkscape and our laser at [[Equipment/Laser_Cutter_Inkscape]]
* If the jog buttons (arrow keys moving the laser head around) are only moving the head in small single steps rather than moving it continuously, make sure that the jog step size is set to 0.0mm in the Jog Settings section of the menu.

== Fixing up a job that went wrong ==

If you messed up a job and, for example, some cut lines weren't cut, you might try to run the job again after deleting all of the lines except the ones that didn't cut. This will work if the origin is in the same place but, depending on the design, it might not be once you delete some lines. To solve this problem, you can run the job with the power set to 1 for all your fix-up lines. This is so low that it will not even mark the material but will show you exactly where the lines will go when you run it again with the correct power settings. You can then line this up correctly before doing your fix-up. Perhaps even set the speed a little lower so you can tell the difference between travel and cut movements.

Alternatively, if you can, keep enough lines to ensure that the origin stays in the same place, then set these lines to power 1 if you don't need them.
Then you can run the job again and everything will be in exactly the same place, no adjustment needed. Alternatively, you could avoid deleting any lines and just set the unwanted lines to power 1. If you have lots of lines however, this might make the cutter spend lots of time doing nothing.

== Fixing strange issues ==

* Etching doesn't work
** Lines are not closed. LaserCut usually warns you about this. Ctrl-a to select all, then Tools->Unite Lines (0.001 should be fine).
** Two copies on top of each other. Copies on top of each other "cancel out" any etching. Delete one copy.
** Test with Menu->Laser->Simulate

* LaserCut will not download to the laser cutter
** Check laser cutter isn't in a paused state
** Restart LaserCut on the PC. (We've not had any usb issues nor needed to restart the laser since upgrading the PC summer 2014).

* Laser cuts things out 2+ times
** Check you don't have two copies loaded on top of each other
** Check it's not set to cut multiple times in LaserCut (this setting is right of the Cut/Engrave/Speed/Power settings)
** Check the laser front panel says "001" at the bottom. If not, press right arrow until the number is highlighted, then down to adjust back to 1, then press return.

* Laser will only cut at the top right of the bed
** Download again with Immediate Mode ticked
** On laser panel, press return (I think?) then right twice (should select the bottom left option), then press return (I think).

*You Hit Emergency stop
** E-M button needs twisting to re-activate
** If that fails - check the circuit breaker inside. From the back of the machine, you want to open the lower flap on the left side, which should be unlocked. Near to the back, there is a breaker board. Flip the flippy bit.

Mat-c: decommissioned

{{RedTool}}

[[Equipment|Equipment]] / PCB Mill

[[File:PCBMill.jpg|thumb|460px|right|PCB Mill]]

[[File:PCB_Mill_software.JPG|thumb|460px|right|PCB Mill software]]

= Summary: DECOMMISSIONED=

The PCB Mill is now decommissioned, do not use. Reason: poor bearings, low quality results, noone using it. Not worth maintaining.

The PCB mill is a computer controlled (CNC) tool that can be used to cut the tracks for printed circuit boards (PCB). Training is required before members use the equipment because it is easy for users to damage themselves and the tool. Maximum travel is about 300mm in the Y direction, about 190mm in X, and 35mm in Z.

Machine is a generic 'CNC 3020', easily searchable on e.g. youtube for videos of use and configuration:

* Configuration with LinuxCNC [http://www.youtube.com/watch?v=ewtDYvcFZZ4 video]

== Owners ==
* [[user:Zoomzoomluke|Luke Twydell]]
* [[user:RobCopcutt|Robert Copcutt]]
* Adrian van den Heever
* Mark Tillotson
* Alberto Santos

== Health and Safety ==
* Power supply to be switched off when changing tools.
* All cutting tools to be kept in their holders until they are required.
* Keep work area clear of waste material and offcuts.
* Check equipment for defects before each use to minimise the risk of possible electrical faults or fire.
* Carbon Dioxide extinguisher to be available for any electrical fires.
* Wear eye protection.

The risk assessment is at [[Equipment/PCB_Mill/RA]].

== Instructions ==
* '''Do not turn the black knobs on any of the three motors.''' Doing so may generate large voltages and damage the control board. Move only by command from the PC.

'''Initial Inspection'''
Check machine for clearance
Check X and Y axis for “Wiggle” - Indicative of under-tightened lead screw or loose grub screw on motor coupling

'''Tools Required'''
Allen Key
60 degree 0.1mm V-bit
0.8mm Carbide Drill
0.8mm Carbide 2flt End Mill (can also be used instead of the 0.8mm)
Spanners for Collet Lock Nut
Collet Lock Nut
3.175mm / 0.125"Collet

'''Procedure for Eagle BRD Files'''
This guide assumes you have your board design produced in Cadsoft Eagle.

* Have you BRD file in a subdirectory on a USB stick.
* With your eagle BRD file, drag it onto the eagle icon on the desktop.
* Within the board window, open the CAM processor (CAM Processor).
* Open the custom CAM job (File - Open - Job…).
* Open “Makespace_PCB_Mill-Eagle7.2.cam”.
You should not need to change any options unless you have an odd layout.
* Press the “Process Job” button and close the CAM processor when complete. ''Do not save the JOB unless you want to save your own copy onto removable media.''

You gerber files should now be with your BRD file.
* Drag the parent folder of your gerber files onto the “Make GCode” icon on the desktop.
Watch the output window for any errors.

''Common errors usually relate to bad outline. This is often caused by a component in eagle BRD has it’s layout on the dimension layer, causing overlapping / conflicting outlines.''

* Start PCBMill (LinuxCNC)

* When LinuxCNC has started, switch on the “Drive” switch on the mill.
* Ensure E-Stop is released.
* Press the “Power” icon in LinuxCNC.
* Press the “Home All” button to home the machine. Keep fingers, objects etc off the machine to prevent the head crashing into said objects. ''Be ready to hit ESC or E-Stop if you notice the cutting head on a path to destruction.''
* For 2 sided boards, place the PCB material on the right side of the bed on top of 2 tooling pins. Otherwise place the board to the left hand side of the bed.
* Secure the blank PCB material onto the machine bed using the appropriate clamps and with at least 5 pieces of copier paper under the board.
* First secure the bottom two hex bolts ensuring the probe wire is making contact with the copper board.
* Then secure the remaining clamps around the board with the black knobs.

'''Copper Engraving'''
* Open your top copper layer file (named “front.ngc”) (if 2 sided board - otherwise open "back.ngc")
* Press the “Change Tool” button to move the head to the tool change position.
* Fit the V-bit. Always use a new V-bit at the start of the job.
* Use the PC keyboard’s arrow keys to jog the head (hold SHIFT for jog faster) above where you would like the PCB to be cut. Ensure you stay clear of any clamps. You MUST leave at least 5mm gap from the edge of the PCB material or any tooling pins or clamps.
* For front.ngc this should be the bottom left of the area you wish to engrave, for back.ngc it should be the bottom right.
* Press the “Set Origin” button under the appropriate 1sided or 2sided tab. The tool will probe the PCB blank. Ensure what is about to be probed is conductive and connected to the probe otherwise you WILL break a tool.
* Press the Run button (Blue Forward Arrow or “R” Key)
* The following the onscreen instructions, the board will then be probed. DO NOT HAVE THE SPINDLE RUNNING!
* If while probing it looks like the tool head is going to hit a solid object like a clamp, press the ESC key!
* When probing is complete, follow the on screen instructions (Turn spindle on and at 100%). Then press “S <Resume>”
* When finished milling. Stop the spindle.

Repeat the above for the second side (if required) ensuring you flip the board over to the other side of the machine bed. Press the "Park Head" button to give you clear access to the board.

'''Drilling'''
* Load the “drill.ngc” file.
* Press “Change Tool”
* Fit a 0.8mm drill (or end mill if you prefer not to change tool again) The drilling may not be as sharp with the end mill but most times the results are acceptable.
* Press “Zero Tool (Workpiece)”
* Switch on spindle and press the Run button again.
* Follow any on screen instructions. Ignore any tool change requests and press S (or pause) to resume.
* When drilling is complete. Switch off spindle.

'''Outline Routing'''
* Load the “outline.ngc” file.
* Press “Change Tool” and fit a 0.8mm end mill if not already fitted.
* Press “Zero Tool (Workpiece)”
* Start spindle.
* Press the Run button.
* Follow any on screen instructions.
If board comes loose during outline milling, immediately press the ESC key and switch off spindle. A loose board can cause injury and machine damage.
*When outline milling complete. Switch off spindle.

'''Use a vacuum cleaner to remove dust from board BEFORE attempting to remove the board from the machine. DO NOT be tempted to “blow” the dust off the board at any point in the milling process.'''

* Press the "Park Head" button.
* Switch off drive switch and press emergency stop.
Remember to pay for your boards in the honesty box.
* Put the used V-bit into the box for recycling.
* Clean the machine thorougly.
If you are the last to use the machine, shut down the PC.

'''Prices'''
Single Sided
£4.00 per full board
£2.00 for half board
£1.50 for anything a quarter of a board or less.

Double Sided
£5.00 per full board
£2.50 per half board
£2.00 for anything a quarter of a board or less.

If you supply your own material, the tooling charge is 50p. You MAY use a used engraving bit for free (on your own material only) but your results may be less than optimal.

Equipment/Laser Cutter Inkscape

2015-09-02T01:49:35Z

Mat-c: /* Rounded rectangles */

=Inkscape tricks=

A selection of hints to get the best out of Inkscape with our laser cutter. This applies to Inkscape 0.48.4.x and later, if you have an earlier version you should upgrade.

==Page and grid setup==

Set the default units (file->preferences) to mm. Then design everything in mm. These are preserved in dxf (choose mm as the units when saving) and you won't have to resize in the laser software.

At the same point you can create a grid, I use a 1cm grid with 1mm minor lines - select the ''''Grids'''' tab and click ''''New'''' to create a new rectangular grid, for the one I use set units to mm, spacing to 1 and major grid line every 10. I change the colours so I can see the major grid lines even when zoomed in fully.

Now save your document as "MyDefaultInkscapeDocument" and use it to start every project you work on :)

This is a (zipped) default inkscape document (mm as default and 1mm/1cm grid) [[File:DefaultInkscape01.zip]]

==Version 0.91==

0.91 is latest and greatest. It very occasionally crashes (PC) compared to previous version (rock steady). Worth upgrading. Has newer image tracing options, but best of all, you can put formulae into its number boxes. So if your circle is as 0.543 mm and you want to move it right 1mm you can edit it to 0.543+1 mm and it sorts it all out for you. Also *2, /2, etc are handy for scaling.

==Preferences==

Find step and change it to something sensible like 0.5 mm. (Edit -> Preferences -> Behaviour -> Steps). Also change to inset/outset to 0.075 (ie half laser kerf). Now you have a 1mm grid and 0.5mm nudge increments. Shift-arrows give 5mm increments.

==General hints==
Use fill and don't use stroke (turn it off each time you create a shape). Stroke paths show the thick outline, and this confuses the sizing and bounding box for laser cut things. Fill mode for shapes makes everything work better. For shapes with holes, make it show self intersections as holes. This is closest to what a laser cutter will do. Menu: Object -> Fill and Stroke. Right hand side, click the "Fill" tab. Click the icon second from the right, looks a bit like a heart with a hole in it.

==Grids==

By default Inkscape won't actually use the grid, the buttons on the far right allow you to enable snap (first button from the top), to bounding boxes (second from top and subsequent four) and path nodes (the next group down). If you're not getting the snapping behaviour you expect play with turning these on. When snapping to path points it'll use the point closest to your mouse when you're dragging, so it matters where on the path you click!

I find it easiest to get a sense of how big the piece is going to be if I set the page dimensions to those of the laser cutting bed, i.e. 900x600mm. You can do this from ''''File->Document Properties...'''' then entering a custom size, remember to change units to mm.

==Outline mode==

Inkscape can be put into outline mode, allowing you to see objects which have neither stroke nor fill. This is great because adding a stroke changes the dimensions of the object (slightly, but potentially enough to matter) and adding a fill makes it hard to see what you're doing. Select from ''''View->Display Mode->Outline''''. As an alternative a default fill with opacity of 10% works nicely when creating compound objects.
Turning off stroke for each shape achieves the same result (make sure you give it a fill colour so you can still see it...)

==Text on a path==

Easy to do, create a path, create some text and use the ''''Text->Put on Path'''' menu item. With the text selected you can use the letter and word spacing controls to get the text to completely fill the path (I needed this for the plaque as we wanted the lists of names to butt up to each end of the shape). At this point the text and the path are coupled together, so while you can move the text away if you delete or change the path it'll alter. To get outlines ready for the cutter select the text object and do ''''Path->Object to Path'''', you can then delete the original path object used to flow the text.

==Rounded rectangles==

If you try to use these the cutter will largely ignore them. Use the ''''Path->Object to Path'''' to convert them into a generic path before exporting. Same for all boxes and circles.

Alternatively, enable the "use ROBO-Master type of spline output" (an option during saving) if your version of Inkscape supports it.

==Dashed paths==

The laser won't pay any attention to stroke styles you set in Inkscape. Recent versions, however, include an extension under ''''Modify Path -> Convert to Dashes'''' which will render whatever stroke style you've selected.

==Engraving text==

Regular fonts used by Inkscape and everything else are outline fonts, that is to say they're defined as a filled shape. When used by the laser cutter the laser will cut the outline of the font, which looks great for large characters but often very badly (and slowly) for small typefaces. There's an extension at http://www.evilmadscientist.com/2011/hershey-text-an-inkscape-extension-for-engraving-fonts/ which allows for the use of engraving fonts where the font is defined in terms of the path used by the cutting tool rather than an outline.

Note - the version of the library at that link is broken with modern (0.48.4) versions of Inkscape, I've fixed the problem and uploaded a patched version to https://dl.dropboxusercontent.com/u/70831580/HersheyText.zip

==Exporting==

In the latest version of inkscape you have an option from ''''File->Save As'''' to save as ''''Desktop Cutting Plotter (AutoCAD DXF R14)''''. With the default options this seems to work perfectly with the laser, dimensions are preserved etc. If you don't have this option upgrade your version of inkscape, it appeared some point over the last month or two.

Mat-c: /* Page and grid setup */

=Inkscape tricks=

A selection of hints to get the best out of Inkscape with our laser cutter. This applies to Inkscape 0.48.4.x and later, if you have an earlier version you should upgrade.

==Page and grid setup==

Set the default units (file->preferences) to mm. Then design everything in mm. These are preserved in dxf (choose mm as the units when saving) and you won't have to resize in the laser software.

At the same point you can create a grid, I use a 1cm grid with 1mm minor lines - select the ''''Grids'''' tab and click ''''New'''' to create a new rectangular grid, for the one I use set units to mm, spacing to 1 and major grid line every 10. I change the colours so I can see the major grid lines even when zoomed in fully.

Now save your document as "MyDefaultInkscapeDocument" and use it to start every project you work on :)

This is a (zipped) default inkscape document (mm as default and 1mm/1cm grid) [[File:DefaultInkscape01.zip]]

==Version 0.91==

0.91 is latest and greatest. It very occasionally crashes (PC) compared to previous version (rock steady). Worth upgrading. Has newer image tracing options, but best of all, you can put formulae into its number boxes. So if your circle is as 0.543 mm and you want to move it right 1mm you can edit it to 0.543+1 mm and it sorts it all out for you. Also *2, /2, etc are handy for scaling.

==Preferences==

Find step and change it to something sensible like 0.5 mm. (Edit -> Preferences -> Behaviour -> Steps). Also change to inset/outset to 0.075 (ie half laser kerf). Now you have a 1mm grid and 0.5mm nudge increments. Shift-arrows give 5mm increments.

==General hints==
Use fill and don't use stroke (turn it off each time you create a shape). Stroke paths show the thick outline, and this confuses the sizing and bounding box for laser cut things. Fill mode for shapes makes everything work better. For shapes with holes, make it show self intersections as holes. This is closest to what a laser cutter will do. Menu: Object -> Fill and Stroke. Right hand side, click the "Fill" tab. Click the icon second from the right, looks a bit like a heart with a hole in it.

==Grids==

By default Inkscape won't actually use the grid, the buttons on the far right allow you to enable snap (first button from the top), to bounding boxes (second from top and subsequent four) and path nodes (the next group down). If you're not getting the snapping behaviour you expect play with turning these on.

[[Equipment|Equipment]] / Warco Mill

[[File:warco_mill.jpg|thumb|460px|right|Warco Mill]]

= Summary =
(This machine has been purchased but not yet opened to users.)

The Warco mill can be used to machine objects from a wide range of materials. Training is required before members use the equipment because it is easy for users to damage it, and serious injuries, or fatalities, are possible. The machine has a table 660 x 152mm that can move 37cm in the X direction, 15cm in the Y and 34cm in the Z direction.

== Owners ==
* Diana Probst
* Mat Cook
* Roger Smith

== Health and Safety ==
* Power supply to be disconnected when changing tools.
* All cutting tools to be kept in their holders until they are required.
* Waste material/offcuts to be kept clear of work area.
* Equipment will be checked for defects before each use to minimise the risk of possible electrical faults or fire.
* Carbon Dioxide extinguisher to be available for any electrical fires
* Eye protection to be worn when using the equipment.
* Risk assessment: https://docs.google.com/viewer?a=v&pid=forums&srcid=MDgwNzUyNzQ4MjA0NjE0MDY2NDIBMTU4NTI2NjEyMjIzOTU5MDkyODQBdmpubUpFanBkTklKATAuMQEBdjI

<b>THE MILL CAN CAUSE SERIOUS INJURY. ONLY APPROVED OPERATORS ARE PERMITTED TO USE IT.</b><br>

To get the required training to become an approved operator please contact one of the owners.

The owners will help users make the best use of the mill but it must be emphasised that learning to take full advantage of all its capabilities takes months of practice. The owners have limited time so members will need to take responsibility for much of their own training. More details about the training can be found at

* [[Equipment/WarcoMill/Training|Mill Training]]

== Instructions ==

== Tips & Tricks ==

Use a conventional milling cut to get the part to approximately the final size. With a conventional cut the cutting surface and the work piece are moved in opposite directions. A climbing cut is where the cutting surface and the work piece are moved in the same direction. It produces a better finish but puts extra strain on the cutting tool AND IS MORE LIKELY TO BITE, TAKE UP THE BACKLASH, BITE FURTHER AND BREAK THINGS. Therefore only use conventional (opposing directions) cutting. (Climb cuts are only to be used for very small finishing pass operations, usually not in steel, where tool biting is not a concern).

When drilling, start with a spotting drill (centre drill at a push) to make sure that the hole starts exactly centre. It is usually OK to drill to a depth of 3 to 4 diameters in a single pass (less with a centre drill). After that withdraw the drill every diameter of cutting depth to clear the swarf. Use cutting fluid beyond a depth of about 2 diameters (and always in steel). Be aware that halving the diameter of a drill reduces its strength 8 fold. Small drills break very easily and broken tools present a hazard and are exceptionally difficult to remove. Much much less pressure is needed to drill small diameter holes. Use just enough pressure to create long curly chips. Look up the appropriate rotation speed for the drill. The Warco cannot spin fast enough for drills below about 2mm.

== Maintenance ==

* Clean away all swarf at the end of a work session with a brush or vacuum. Do not blow because this can send chips where they can damage the machine. Bare hands are very easily injured by the sharp surfaces.

== Further Information ==

Specification: [http://www.warco.co.uk/Warco%20Brochure.pdf]

Spindle: 3MT (we have the 3MT version). This is NOT compatible with the ML7 lathe headstock which is 2MT.

= Laser Cutter Training =

This page documents the process for being trained on the Laser Cutter, and the list of members who have completed that training.

== Summary ==

Training takes place in three main steps:
* Group Training of 1-4 members, going through the equipment and how to use it (~1hr)
* Individual Training Task, where an individual member is set a task to complete to prove and improve understanding (~30min each)
* Project Oversight, where more experienced users oversee the projects being undertaken when cutting (first 2-3 projects)

Training on the Laser Cutter is run by the Laser Cutter Owners. The Laser Cutter Owners are a group of people responsible for maintaining and training on the laser cutter, and hence have been trained to train, and trained to perform the weekly and monthly maintenance on the laser cutter.

== Booking ==

Sessions are advertised on '''http://meetup.makespace.org'''
* For discussing training, or requesting additional slots if needed, use the mailing list thread: [https://groups.google.com/d/topic/cammakespace/vNrS07zVuY0/discussion Training : Laser Cutter]

Notes:
* You can only be trained if you have your name allocated to a slot (groups will be restricted to four at a time, so please don't make up additional spaces)
* You must do the group and individual training on the same day

== Group Training ==

The group training introduction structure, suitable for 1-4 members at a time in a 1 hr session.

Introduction of main components
* Laser
* Cutting Mechanics
* Water Cooler System
* Filter
* PC
* Materials (what it can cut, supply)

Checks for everyone to do
* Check in use, looks ok
* Check water bath, temperature

Powering Up
* Turning on filter (Tick = ok, Warning = tell the owners, Cross = don't use it and tell the owners)
* Turning on Laser and warmup, what to do if doesn't power up
* Turning on PC and starting software

LaserCut Project walkthrough (using M+S+text keyring example)
* Package function, drawing, import file types
* Bed dimensions
* Paths, yellow dots, 'united' shapes
* Blue dot, Immediate mode
* Layers and colours
* Through cut, surface cut and engraving, speeds and strengths
* Various steps to build keyring design (shapes, text, uniting, layers, alignment, scaling, layers)
* Job ordering
* Saving
* Download as immediate, delete, download current

Laser Operation
* Lid
* Control panel, escape
* Moving head XY, indicator laser, datum
* Moving Z
* Focus
* Start position and test
* Start, pause and emergency stop function
* Do job, pause/open lid, restart

Laser Hazards
* Process and progression for normal operation failure (fire) - pause, open, move, CO2
* Process for abnormal operation failure (mechanical/jam) - emergency stop, open, move, CO2
* Ensure confident of process

Power Down
* Switch off laser
* Switch off filtration
* Clean any residue from the bed or bottom tray
* Close lid

== Individual Training Task ==

The individual task to get familiar, prompt questions and check understanding:

Task
* Make a personalised focus tool
* Square acrylic of appropriate size
* Member's name, "Focus Tool", keychain hole
* Should use full cut, surface cut, engrave
* Should demonstrate all steps, size, appropriate ordering, positioning

Steps
* Set individual to work, don't prompt but do answer questions (or pose if needed)
* Talk through design once done, question/check things etc
* Proceed to lasering (watch carefully all steps)
* Ask to stop job/restart, question escalation process

Assuming all ok:
* Get them to read the health and safety notes about operation and materials
* Add to the trained member list!

== Project Oversight ==

For next 2-3 projects, ensure member will find another more experienced trained user to support them (second pair of eyes)

= Laser Cutter Training =

This page documents the process for being trained on the Laser Cutter, and the list of members who have completed that training.

== Summary ==

Training takes place in three main steps:
* Group Training of 1-4 members, going through the equipment and how to use it (~1hr)
* Individual Training Task, where an individual member is set a task to complete to prove and improve understanding (~30min each)
* Project Oversight, where more experienced users oversee the projects being undertaken when cutting (first 2-3 projects)

Training on the Laser Cutter is run by the Laser Cutter Owners. The Laser Cutter Owners are a group of people responsible for maintaining and training on the laser cutter, and hence have been trained to train, and trained to perform the weekly and monthly maintenance on the laser cutter.

== Booking ==

Sessions are advertised on '''http://meetup.makespace.org'''
* For discussing training, or requesting additional slots if needed, use the mailing list thread: [https://groups.google.com/d/topic/cammakespace/vNrS07zVuY0/discussion Training : Laser Cutter]

Notes:
* You can only be trained if you have your name allocated to a slot (groups will be restricted to four at a time, so please don't make up additional spaces)
* You must do the group and individual training on the same day

= Laser Cutter Training =

This page documents the process for being trained on the Laser Cutter, and the list of members who have completed that training.

== Summary ==

Training takes place in three main steps:
* Group Training of 1-4 members, going through the equipment and how to use it (~1hr)
* Individual Training Task, where an individual member is set a task to complete to prove and improve understanding (~30min each)
* Project Oversight, where more experienced users oversee the projects being undertaken when cutting (first 2-3 projects)

Training on the Laser Cutter is run by the Laser Cutter Owners. The Laser Cutter Owners are a group of people responsible for maintaining and training on the laser cutter, and hence have been trained to train, and trained to perform the weekly and monthly maintenance on the laser cutter.

== Booking ==

Sessions are advertised on '''http://meetup.makespace.org'''
* For discussing training, or requesting additional slots if needed, use the mailing list thread: [https://groups.google.com/d/topic/cammakespace/vNrS07zVuY0/discussion Training : Laser Cutter]

Notes:
* You can only be trained if you have your name allocated to a slot (groups will be restricted to four at a time, so please don't make up additional spaces)
* You must do the group and individual training on the same day

[[File:Makespace-laser-cutter.JPG|thumb|460px|right|Our LS6090 PRO Laser Cutter]]

= Summary =

We have two LS 6090 PRO Laser Cutters. Each has a working area of 900mm by 600mm, and is powered by a 60w CO2 Water Cooled Laser Tube that can engrave and cut through materials such as wood, plastic, card, leather, fabrics, up to about 10-15mm thick (note, it can not cut metal). The laser cut is approximately 0.15mm wide, and a job can take a few seconds through to tens of minutes depending on material thickness and design complexity.

We have dedicated PCs running LaserCut 5.3 software to import, prepare and download jobs to the Laser Cutter. It can import various formats, with DXF being the most commonly used, so various software packages can be used to create your designs.

Here are some examples of laser jobs we've run (please add a photo of yours any time you do a job!)

= Using the Laser Cutter =

The laser cutter is a great way to easily produce accurate and complex 2D forms in various materials, and can be designed for with limited experience in various drawing or CAD applications. At the same time, it is an expensive tool with real risk of injury and fire, so is very important you know how to use it to avoid damaging yourself and the machine. '''You must only use the laser cutter if you have been trained, and if you are ever in any doubt about something, please ask for assistance.'''

== Owners ==

The Owners are those who have volunteered to be in charge of the laser cutter, organising maintenance, responding to technical issues and generally being a point of contact. The current Owners of the Laser Cutter are:

* [[User:Mat-C|Mat Cook]]
* [[User:DianaProbst|Diana Probst]]
* [[User:stevancw|Stevan Wing]]
* Owners who are a little less current, but may still be able to help:
** [[User:Simon|Simon Ford]]
** [[User:Barhamd|David Barham]]
** [[User:Nickcadsoftuk|Nick Johnson]]
** [[User:Tmonca|Toby Moncaster]]

== Trainers ==

The Trainers are those who have volunteered to teach others to use the laser cutter and to promote good working practice. The current Trainers for the Laser Cutter are:

* Brian Starkey
* [[User:stevancw|Stevan Wing]]
* [[User:Mat-C|Mat Cook]]

* Currently slightly less frequent trainers are:
** Martin de Selincourt

<b>YOU CAN ONLY USE THE LASER CUTTER IF YOU HAVE BEEN TRAINED</b><br>
and have been added to the [[Equipment/Laser_Cutter/Training#Trained_Users|Trained Users]] list by one of the Owners
</div>

To get trained on the laser cutter and be added to the qualified user list, you will need to arrange for a training session with one of the Laser Cutter Owners.

If you'd like to arrange training, please see:
* [[Equipment/Laser_Cutter/Training|Laser Cutter Training]]

== Health and Safety ==

The laser cutter is a potentially dangerous piece of equipment which must only be operated by members who have received appropriate training and who take due care. The top things to always remember when using the laser cutter are:
* '''ONLY USE THE LASER CUTTER IF YOU ARE ON THE LIST OF TRAINED USERS'''
* '''NEVER LEAVE THE LASER CUTTER RUNNING UNATTENDED'''
* '''KNOW WHAT TO DO IF A FIRE BREAKS OUT'''
* '''NEVER CUT MATERIALS THAT YOU DON'T KNOW ARE SAFE'''

As a trained user, you should be very aware of the following risks and how to deal with them:

'''FIRE (under normal operation)''' - Cutting at the wrong speed or the wrong power can result in the material igniting
* You must watch the cutter at all times and be prepared to abort the job if problems occur
* Small flashes of flame that don't hang around for a fraction of a second are acceptable, but any more is rare and not acceptable
* If a fire does take, this is the process you should follow (from minor to major):
** Press "pause" (the same button you started the job with) - This will turn the laser off so no more heat enters, and assuming the flame goes out, you can press "start" for the job to continue where it left off
** Open the lid - With the job paused, you can open the lid to blow out the flame. Again, it is possible to re-close the lid and continue where you left off
** Move the material from under the laser head assuming safe to do so (so it doesn't damage the optics; alternatively send the laser to home/datum), and smother with a spare sheet of material or blow out
** Use the workshop CO2 extinguisher to extinguish the flame
* You should also make a note in the log if any of this happens with associated materials and settings so we can keep track of any particular materials/settings we should look at

'''FIRE (abnormal operation)''' - If the head gets stuck or something else goes wrong, ignition could happen much more suddenly or intensely
* You must watch the cutter at all times and be prepared to abort the job if problems occur
* If the head gets trapped (e.g. tomb-stoning of a piece, mechanical failure) or any other problem occurs that causes or could cause fire, this is the process you should follow:
** Hit the emergency stop
** Open the lid and move the material from under the laser head assuming safe to do so (so it doesn't damage the optics)
** Blow out, smother with a spare sheet of material, or use the CO2 extinguisher to extinguish the flame as appropriate
* Ensure a Maintainer looks at the machine before it is brought back in to action if it is not obvious what went wrong and all is ok
* You should also make a note in the log if any of this happens with associated materials and settings so we can keep track of any particular materials/settings we should look at

'''FUMES''' - The laser cutting process will release different smoke and fumes depending on the material.
* Never cut PVC or a material you are not sure is safe. When PVC is heated it releases chlorine gas, this mixes with the moisture in the air and the result is hydrochloric acid which is toxic to humans and corrosive to machines.
* Ensure the filter is on and the cutter lid stays closed for a while after a job to allow the fumes to clear.
* If you are feeling strange, think the fume build up is too much, or for any other reason you are unsure, stop the job.

'''TRAPPING''' - The head and bed of the cutter can be moved by the front panel menu or programs in the machines memory.
* Be careful when working inside the cutting area or with the lid open not to trap hands, hair, clothing or anything else.
* Always check the machine for unexpected items that may have fallen in before closing the lid.
* Do not attempt to climb into the machine!

'''LASER BURNS/LIGHT''' - A 60W laser can do real damage.
* The laser should be safe within the confines of the machine, and cut-off automatically when the lid is open (although this should not be relied upon). The top window is safe to look through during a job, but do not attempt to interfere with these windows or the laser or in any way invent some way to look at the laser.
* Do not tamper with the laser cutter, or any interlocks. All side panels of the laser should always be closed and locked whilst the machine is plugged in.
* Do not put metal in the laser cutter.

== Can I cut it? ==

*Woody things
** Wood: yes! (be careful of fire)
** Plywood: yes if it is "laser ply". Normal plywood has non-laser compatible glue
** MDF: no. Clogs up our filters and smells bad.
** LaserMDF: no. It produces perhaps 50% the gunk of MDF but still too much.
** Cork: yes. Let us know how it goes!

*Plasticy things
** Acrylic / Perspex: yes!
** PVC/Vinyl: absolutely not. Produces chlorine.
** Silicone: we tried it with very limited success. A mm or two perhaps, anything else chars and doesn't cut.
** White Delrin/Acetal: yes with great care. Make sure filters running well. Don't open lid too quickly. Check for fumes and fire.
** Black Delrin/Acetal: no. contains carbon black which can be toxic.
** Teflon: no (it is toxic)
** Nylon: no (consult an owner)
** Polythene/polyethylene: no (consult an owner)
** Lexan/Polycarbonate: no (consult an owner)
** Polypropylene: yes just. You must clean the bed. It will cut up to about 2mm. It's not a great quality cut, but just about doable. Fire risk.
** GPPS / Polystyrene / HIPS in thin solid sheet form: maybe. ask owner to help. NO FOAM (it's highly flammable)

*Papery things
** Card/Paper: yes! (be careful of fire)
** Tissue: yes if super super really careful (be REALLY careful of fire, have emergency procedure in place before you start)

*Metally things
** Metal of any thickness doesn't cut. The surface can be engraved with a paint application. LMM6000 Surmark/Thermark has been tested and is suggested for use, but expensive. The owners suggest a speed of 800 and maximum power.

*Exotics
** Fibre glass: no (unknown resin, glass particles)
** Carbon Fibre: no
** Slate: engravable for good effect

== Instructions ==

To use the laser cutter, you must have been trained and have had your name added to the trained user list; these instructions are not a substitute for this training. See the training section to understand how you can become qualified to use the laser cutter.

Although not a requirement, it is recommended someone else trained is also present when using the laser cutter. Having two pairs of eyes helps avoid forgotten steps, allows for double checking, clarifications and discussions, and ensures a greater pool of experience is both present and being built up as the laser is used.

'''Power Up'''

Give the machine a quick visual check. Make sure that there is nothing left on the bed, the water reservoir of the chiller looks normal, and that the equipment has no obvious damage or signs of being out-of-action. If the bed looks like it has residue on it, give it a wipe with IPA and a cloth.

Turn on primary switch on the trunking marked 'Laser'. The air filter system to the right of the laser cutter should start as should the air pump and the chiller. It should power up, make a decent amount of noise, and the lights should indicate the filter is in good condition (i.e. no need for replacement).

Make sure the lid is closed. Turn on the laser using the key on the right hand side. The inspection lamp should come on, a satisfying hum start up, and the cutter go into doing its self-checks.

Before doing any job, the laser should be left to warm up for 4-5 mins. While the machine warms up, power on the adjacent PC and start the LaserCut application from the desktop. During this time the water temperature shown on the chiller should drop from ambient temperature to the usual setting of 18C.

'''Load your Design'''

The PC software has an import facility which seems to be happy taking AutoCAD 2004 DXF files and other formats. The workspace of the laser bed is represented as the workarea in the LaserCut software. If the import doesn't do what you want size-wise, you can select the whole image and then use the 'size' command from the drop down menu to set the dimension you want. Clicking on the three dots ... symbol will adjust the other axis in the same proportion (keeping the aspect ratio fixed). Selecting the 'centre on bed' option will locate your imported drawing on the centre of the machine's cutting bed.

'''Assign Settings to Colours'''

Each part of your drawing that is assigned a different colour can have a different cut action assigned. Each colour will appear on the menu on the right hand side of the screen with numbers related to power and speed of the laser which will be used for the colour.

The main options are to Cut (line) or Engrave (raster fill). A marking on the material is a Cut. For each material and cutting depth required, a corresponding speed and power must be entered. The handbook provided with the machine gives suggested values for various materials but these should be considered as a starting point for a test. See the '''Power and Speed Settings''' section for our guidelines and experiences for these settings.

'''Download to the Cutter'''

Your drawing will feature a blue dot which represents the starting point of the laser; this is by default on the top right corner. In general, you will want to use "immediate" mode, which means this point represents wherever the laser is positioned when you start the job. You can also run the job in absolute mode by unchecking the box, making the job use absolute positioning on the workspace.

To download, select Download and Download Current; the download option will by default call the file on the laser cutter 'LASER'.

'''Set the Focus'''

Before each job, the focus needs to be checked and set by adjusting the height of the bed, and thus the work piece, from the lens. The critical dimension here is 41mm and several gauges made of perspex will be left around the machine. This gauge needs to be a fit between the top surface of the material you intend to cut and the white plastic 'flap' on the lens piece. The height of the table is adjusted using the UP and DOWN buttons. Failure to set the distance correctly will result in an out of focus laser and much bigger (but lower powered) cut line. Always ensure there is clearance between the material and laser head before the head moves.

'''Aligning and Testing the Job'''

The cutter's menu will show the most recent downloaded file highlighted. Pressing the 'test' button will make the head travel along the square maximum extends of the cuts. This shows you that you have the material in the right place, and you have enough of it! You can do this repeatedly, moving the work piece by hand or the laser head using the arrow keys (after hitting ESC), until you are confident you have things where you want them.

'''Cut the Job'''

When happy with the location of the material, close the lid and press 'start' to start the cutter. Watch the head and at least at first be prepared to press the 'stop' button immediately if you find you are burning massive holes in your work piece! This goes back to doing some tests on a sample of your material and making sure you are happy with the cut speeds and power you have selected. You should stay near the cutter at all times and be prepared to pause it or stop it in the event of fire.

<span style="color:red">'''DO NOT EVER LEAVE THE CUTTER UNATTENDED'''</span>

'''Finishing'''

The end of the job is signified by a beep. Waiting a few moments for the exhaust pump to clear any remaining smoke is a good idea, especially with wood, and will limit the build up of smells in the rest of the workshop. Remove your work piece, ensuring that all parts are cleared from the bed of the machine.

'''Power Down'''

The cutter is turned off using the key switch, then the air filtering system with the green rocker switch. Shut down the PC and double check that everything is left in a safe state for the next user.

'''Clean the bed of debris using the soft brush, then wipe down the bed using IPA and a cloth.'''

If you have been cutting particularly 'dirty' materials, most notable MDF and Ply which leave a sticky residue then you will need to use the course side of one of the oven pads and lots of 'elbow grease'. Residue on the bed can impact the next persons' job so please make the effort to clean up and leave the cutter as you would wish to find it.

Go away excited by what you can make and come back with lots more drawings!

== Power and Speed Settings ==

In due time we will try to build up a large sample stock of materials and record the values which work best. Here are the sample material tests we have so far:

<gallery>
File:Laser-schmoo-3mm-acrylic.JPG|3mm Acrylic
File:Laser-schmoo-10mm-acrylic.JPG|10mm Acrylic
File:Laser-schmoo-9mm-mdf.JPG|9mm MDF (note: do not cut MDF - see above!)
</gallery>

Settings to get you started:
*3mm Acrylic: Speed 12, Power 100, Corner power 100
*5mm Acrylic: Speed 6, Power 100, Corner power 100
*Acrylic shallow cut: Speed 30, power 50, corner power 50
*Etching acrylic: Speed 400, Power 50, Spacing 0.05

== Tips & Tricks ==

* If the laser cutter's user interface does not seem to respond/do what you want, hit "ESC" to return to 'normal mode'.
* The opaque white acrylic needs slightly stronger settings for surface cuts as they are not as visible as in the transparent acrylic (i.e., for similar effect you need a deeper cut). Otherwise seems to cut equivalently to transparent acrylics.
* If you want a tight fit of pieces or very accurate sizing, keep in mind that the laser beam has a width of just over 0.1 mm (maybe 0.11 or 0.12 mm). So all exterior cut lines should be offset by 0.05 mm; you can do this very easily in the LaserCutter Software with the "Offset" tool (units are in mm, so enter '0.05' and select 'Outer').
* The DXF file format stores values only (not values and units). The internal units in the LaserCutter are in mm. If you set your document's units to mm in the exporting CAD system it should work fine, but generally it is a good idea to have a piece of geometry of known length, e.g. a line 100mm long, or a box of known size around your design. This makes adjusting the scaling a lot easier.
* If you want to export a DXF from Inkscape (which is a great, free vector drawing package), then make sure you do "Object to path" from the Path menu for the whole object and then during the export stage, enable "use ROBO-Master type of spline output". This should make sure all the curves and so on work.
* There's now a page to help with Inkscape and our laser at [[Equipment/Laser_Cutter_Inkscape]]
* If the jog buttons (arrow keys moving the laser head around) are only moving the head in small single steps rather than moving it continuously, make sure that the jog step size is set to 0.0mm in the Jog Settings section of the menu.

== Fixing strange issues ==

* Etching doesn't work
** Lines are not closed. LaserCut usually warns you about this. Ctrl-a to select all, then Tools->Unite Lines (0.001 should be fine).
** Two copies on top of each other. Copies on top of each other "cancel out" any etching. Delete one copy.
** Test with Menu->Laser->Simulate

* LaserCut will not download to the laser cutter
** Check laser cutter isn't in a paused state
** Restart LaserCut on the PC. (We've not had any usb issues nor needed to restart the laser since upgrading the PC summer 2014).

* Laser cuts things out 2+ times
** Check you don't have two copies loaded on top of each other
** Check it's not set to cut multiple times in LaserCut (this setting is right of the Cut/Engrave/Speed/Power settings)
** Check the laser front panel says "001" at the bottom. If not, press right arrow until the number is highlighted, then down to adjust back to 1, then press return.

* Laser will only cut at the top right of the bed
** Download again with Immediate Mode ticked
** On laser panel, press return (I think?) then right twice (should select the bottom left option), then press return (I think).

*You Hit Emergency stop
** E-M button needs twisting to re-activate
** If that fails - check the circuit breaker inside. From the back of the machine, you want to open the lower flap on the left side, which should be unlocked. Near to the back, there is a breaker board. Flip the flippy bit.

'''Reactive Maintenance'''
* 15th Jan 2013, Simon Ford: Laser cutter not powering up, with switching on via key gives no activity whatsoever. No recollection of it cutting out during a job (Alexis), so assume it just stopped turning on at some point. Filter box and power sockets confirmed OK. Diagnosis: RCD in right back panel of Laser reset to off, no obvious reason why. Switching back on brought everything back to life OK.
* 22nd, Simon Ford; 29th, Nicholas - same again.

* Apr 2014, Mat Cook and Diana Probst: after previous changing of chiller water (Roger et al) the pump was complaining of lack of flow. Changed water and filtered, removed small blockage from rubber hose on laser tube.

= Laser Cutter Training =

This page documents the process for being trained on the Laser Cutter, and the list of members who have completed that training.

== Summary ==

Training takes place in three main steps:
* Group Training of 1-4 members, going through the equipment and how to use it (~1hr)
* Individual Training Task, where an individual member is set a task to complete to prove and improve understanding (~30min each)
* Project Oversight, where more experienced users oversee the projects being undertaken when cutting (first 2-3 projects)

Training on the Laser Cutter is run by the Laser Cutter Owners. The Laser Cutter Owners are a group of people responsible for maintaining and training on the laser cutter, and hence have been trained to train, and trained to perform the weekly and monthly maintenance on the laser cutter.

== Booking ==

Sessions are advertised on '''http://meetup.makespace.org'''
* For discussing training, or requesting additional slots if needed, use the mailing list thread: [https://groups.google.com/d/topic/cammakespace/vNrS07zVuY0/discussion Training : Laser Cutter]

Notes:
* You can only be trained if you have your name allocated to a slot (groups will be restricted to four at a time, so please don't make up additional spaces)
* You must do the group and individual training on the same day

* Laser
* Cutting Mechanics
* Water Cooler System
* Filter
* PC
* Materials (what it can cut, supply)

Checks for everyone to do
* Check in use, looks ok
* Check water bath, temperature

Powering Up
* Turning on filter (Tick = ok, Warning = tell the owners, Cross = don't use it and tell the owners)
* Turning on Laser and warmup, what to do if doesn't power up
* Turning on PC and starting software

LaserCut Project walkthrough (using M+S+text keyring example)
* Package function, drawing, import file types
* Bed dimensions
* Paths, yellow dots, 'united' shapes
* Blue dot, Immediate mode
* Layers and colours
* Through cut, surface cut and engraving, speeds and strengths
* Various steps to build keyring design (shapes, text, uniting, layers, alignment, scaling, layers)
* Job ordering
* Saving
* Download as immediate, delete, download current

Laser Operation
* Lid
* Control panel, escape
* Moving head XY, indicator laser, datum
* Moving Z
* Focus
* Start position and test
* Start, pause and emergency stop function
* Do job, pause/open lid, restart

Laser Hazards
* Process and progression for normal operation failure (fire) - pause, open, move, CO2
* Process for abnormal operation failure (mechanical/jam) - emergency stop, open, move, CO2
* Ensure confident of process

Power Down
* Switch off laser
* Switch off filtration
* Clean any residue from the bed or bottom tray
* Close lid

== Individual Training Task ==

The individual task to get familiar, prompt questions and check understanding:

Task
* Make a personalised focus tool
* Square acrylic of appropriate size
* Member's name, "Focus Tool", keychain hole
* Should use full cut, surface cut, engrave
* Should demonstrate all steps, size, appropriate ordering, positioning

Steps
* Set individual to work, don't prompt but do answer questions (or pose if needed)
* Talk through design once done, question/check things etc
* Proceed to lasering (watch carefully all steps)
* Ask to stop job/restart, question escalation process

Assuming all ok:
* Get them to read the health and safety notes about operation and materials
* Add to the trained member list!

== Project Oversight ==

For next 2-3 projects, ensure member will find another more experienced trained user to support them (second pair of eyes)

= Summary =

We have two LS 6090 PRO Laser Cutters. Each has a working area of 900mm by 600mm, and is powered by a 60w CO2 Water Cooled Laser Tube that can engrave and cut through materials such as wood, plastic, card, leather, fabrics, up to about 10-15mm thick (note, it can not cut metal). The laser cut is approximately 0.15mm wide, and a job can take a few seconds through to tens of minutes depending on material thickness and design complexity.

We have dedicated PCs running LaserCut 5.3 software to import, prepare and download jobs to the Laser Cutter. It can import various formats, with DXF being the most commonly used, so various software packages can be used to create your designs.

Here are some examples of laser jobs we've run (please add a photo of yours any time you do a job!)

= Using the Laser Cutter =

The laser cutter is a great way to easily produce accurate and complex 2D forms in various materials, and can be designed for with limited experience in various drawing or CAD applications. At the same time, it is an expensive tool with real risk of injury and fire, so is very important you know how to use it to avoid damaging yourself and the machine. '''You must only use the laser cutter if you have been trained, and if you are ever in any doubt about something, please ask for assistance.'''

== Training ==

<div style="background:#FADADD; border:1px solid #FFC0CB; padding:5px">
<b>YOU CAN ONLY USE THE LASER CUTTER IF YOU HAVE BEEN TRAINED</b><br>
and have been added to the [[Equipment/Laser_Cutter/Training#Trained_Users|Trained Users]] list by one of the Owners
</div>

To get trained on the laser cutter and be added to the qualified user list, you will need to arrange for a training session with one of the Laser Cutter Owners.

If you'd like to arrange training, please see:
* [[Equipment/Laser_Cutter/Training|Laser Cutter Training]]

== Health and Safety ==

The laser cutter is a potentially dangerous piece of equipment which must only be operated by members who have received appropriate training and who take due care. The top things to always remember when using the laser cutter are:
* '''ONLY USE THE LASER CUTTER IF YOU ARE ON THE LIST OF TRAINED USERS'''
* '''NEVER LEAVE THE LASER CUTTER RUNNING UNATTENDED'''
* '''KNOW WHAT TO DO IF A FIRE BREAKS OUT'''
* '''NEVER CUT MATERIALS THAT YOU DON'T KNOW ARE SAFE'''

As a trained user, you should be very aware of the following risks and how to deal with them:

'''FIRE (under normal operation)''' - Cutting at the wrong speed or the wrong power can result in the material igniting
* You must watch the cutter at all times and be prepared to abort the job if problems occur
* Small flashes of flame that don't hang around for a fraction of a second are acceptable, but any more is rare and not acceptable
* If a fire does take, this is the process you should follow (from minor to major):
** Press "pause" (the same button you started the job with) - This will turn the laser off so no more heat enters, and assuming the flame goes out, you can press "start" for the job to continue where it left off
** Open the lid - With the job paused, you can open the lid to blow out the flame. Again, it is possible to re-close the lid and continue where you left off
** Move the material from under the laser head assuming safe to do so (so it doesn't damage the optics; alternatively send the laser to home/datum), and smother with a spare sheet of material or blow out
** Use the workshop CO2 extinguisher to extinguish the flame
* You should also make a note in the log if any of this happens with associated materials and settings so we can keep track of any particular materials/settings we should look at

'''FIRE (abnormal operation)''' - If the head gets stuck or something else goes wrong, ignition could happen much more suddenly or intensely
* You must watch the cutter at all times and be prepared to abort the job if problems occur
* If the head gets trapped (e.g. tomb-stoning of a piece, mechanical failure) or any other problem occurs that causes or could cause fire, this is the process you should follow:
** Hit the emergency stop
** Open the lid and move the material from under the laser head assuming safe to do so (so it doesn't damage the optics)
** Blow out, smother with a spare sheet of material, or use the CO2 extinguisher to extinguish the flame as appropriate
* Ensure a Maintainer looks at the machine before it is brought back in to action if it is not obvious what went wrong and all is ok
* You should also make a note in the log if any of this happens with associated materials and settings so we can keep track of any particular materials/settings we should look at

'''FUMES''' - The laser cutting process will release different smoke and fumes depending on the material.
* Never cut PVC or a material you are not sure is safe. When PVC is heated it releases chlorine gas, this mixes with the moisture in the air and the result is hydrochloric acid which is toxic to humans and corrosive to machines.
* Ensure the filter is on and the cutter lid stays closed for a while after a job to allow the fumes to clear.
* If you are feeling strange, think the fume build up is too much, or for any other reason you are unsure, stop the job.

'''TRAPPING''' - The head and bed of the cutter can be moved by the front panel menu or programs in the machines memory.
* Be careful when working inside the cutting area or with the lid open not to trap hands, hair, clothing or anything else.
* Always check the machine for unexpected items that may have fallen in before closing the lid.
* Do not attempt to climb into the machine!

'''LASER BURNS/LIGHT''' - A 60W laser can do real damage.
* The laser should be safe within the confines of the machine, and cut-off automatically when the lid is open (although this should not be relied upon). The top window is safe to look through during a job, but do not attempt to interfere with these windows or the laser or in any way invent some way to look at the laser.
* Do not tamper with the laser cutter, or any interlocks. All side panels of the laser should always be closed and locked whilst the machine is plugged in.
* Do not put metal in the laser cutter.

== Can I cut it? ==

*Woody things
** Wood: yes! (be careful of fire)
** Plywood: yes if it is "laser ply". Normal plywood has non-laser compatible glue
** MDF: no. Clogs up our filters and smells bad.
** LaserMDF: no. It produces perhaps 50% the gunk of MDF but still too much.
** Cork: yes. Let us know how it goes!

*Plasticy things
** Acrylic / Perspex: yes!
** PVC/Vinyl: absolutely not. Produces chlorine.
** Silicone: we tried it with very limited success. A mm or two perhaps, anything else chars and doesn't cut.
** White Delrin/Acetal: yes with great care. Make sure filters running well. Don't open lid too quickly. Check for fumes and fire.
** Black Delrin/Acetal: no. contains carbon black which can be toxic.
** Teflon: no (it is toxic)
** Nylon: no (consult an owner)
** Polythene/polyethylene: no (consult an owner)
** Lexan/Polycarbonate: no (consult an owner)
** Polypropylene: yes just. You must clean the bed. It will cut up to about 2mm. It's not a great quality cut, but just about doable. Fire risk.
** GPPS / Polystyrene / HIPS in thin solid sheet form: maybe. ask owner to help. NO FOAM (it's highly flammable)

*Papery things
** Card/Paper: yes! (be careful of fire)
** Tissue: yes if super super really careful (be REALLY careful of fire, have emergency procedure in place before you start)

*Metally things
** Metal of any thickness doesn't cut. The surface can be engraved with a paint application. LMM6000 Surmark/Thermark has been tested and is suggested for use, but expensive. The owners suggest a speed of 800 and maximum power.

*Exotics
** Fibre glass: no (unknown resin, glass particles)
** Carbon Fibre: no
** Slate: engravable for good effect

== Instructions ==

To use the laser cutter, you must have been trained and have had your name added to the trained user list; these instructions are not a substitute for this training. See the training section to understand how you can become qualified to use the laser cutter.

Although not a requirement, it is recommended someone else trained is also present when using the laser cutter. Having two pairs of eyes helps avoid forgotten steps, allows for double checking, clarifications and discussions, and ensures a greater pool of experience is both present and being built up as the laser is used.

'''Power Up'''

Give the machine a quick visual check. Make sure that there is nothing left on the bed, the water reservoir of the chiller looks normal, and that the equipment has no obvious damage or signs of being out-of-action. If the bed looks like it has residue on it, give it a wipe with IPA and a cloth.

Turn on primary switch on the trunking marked 'Laser'. The air filter system to the right of the laser cutter should start as should the air pump and the chiller. It should power up, make a decent amount of noise, and the lights should indicate the filter is in good condition (i.e. no need for replacement).

Make sure the lid is closed. Turn on the laser using the key on the right hand side. The inspection lamp should come on, a satisfying hum start up, and the cutter go into doing its self-checks.

Before doing any job, the laser should be left to warm up for 4-5 mins. While the machine warms up, power on the adjacent PC and start the LaserCut application from the desktop. During this time the water temperature shown on the chiller should drop from ambient temperature to the usual setting of 18C.

'''Load your Design'''

The PC software has an import facility which seems to be happy taking AutoCAD 2004 DXF files and other formats. The workspace of the laser bed is represented as the workarea in the LaserCut software. If the import doesn't do what you want size-wise, you can select the whole image and then use the 'size' command from the drop down menu to set the dimension you want. Clicking on the three dots ... symbol will adjust the other axis in the same proportion (keeping the aspect ratio fixed). Selecting the 'centre on bed' option will locate your imported drawing on the centre of the machine's cutting bed.

'''Assign Settings to Colours'''

Each part of your drawing that is assigned a different colour can have a different cut action assigned. Each colour will appear on the menu on the right hand side of the screen with numbers related to power and speed of the laser which will be used for the colour.

The main options are to Cut (line) or Engrave (raster fill). A marking on the material is a Cut. For each material and cutting depth required, a corresponding speed and power must be entered. The handbook provided with the machine gives suggested values for various materials but these should be considered as a starting point for a test. See the '''Power and Speed Settings''' section for our guidelines and experiences for these settings.

'''Download to the Cutter'''

Your drawing will feature a blue dot which represents the starting point of the laser; this is by default on the top right corner. In general, you will want to use "immediate" mode, which means this point represents wherever the laser is positioned when you start the job. You can also run the job in absolute mode by unchecking the box, making the job use absolute positioning on the workspace.

To download, select Download and Download Current; the download option will by default call the file on the laser cutter 'LASER'.

'''Set the Focus'''

Before each job, the focus needs to be checked and set by adjusting the height of the bed, and thus the work piece, from the lens. The critical dimension here is 41mm and several gauges made of perspex will be left around the machine. This gauge needs to be a fit between the top surface of the material you intend to cut and the white plastic 'flap' on the lens piece. The height of the table is adjusted using the UP and DOWN buttons. Failure to set the distance correctly will result in an out of focus laser and much bigger (but lower powered) cut line. Always ensure there is clearance between the material and laser head before the head moves.

'''Aligning and Testing the Job'''

The cutter's menu will show the most recent downloaded file highlighted. Pressing the 'test' button will make the head travel along the square maximum extends of the cuts. This shows you that you have the material in the right place, and you have enough of it! You can do this repeatedly, moving the work piece by hand or the laser head using the arrow keys (after hitting ESC), until you are confident you have things where you want them.

'''Cut the Job'''

When happy with the location of the material, close the lid and press 'start' to start the cutter. Watch the head and at least at first be prepared to press the 'stop' button immediately if you find you are burning massive holes in your work piece! This goes back to doing some tests on a sample of your material and making sure you are happy with the cut speeds and power you have selected. You should stay near the cutter at all times and be prepared to pause it or stop it in the event of fire.

<span style="color:red">'''DO NOT EVER LEAVE THE CUTTER UNATTENDED'''</span>

'''Finishing'''

The end of the job is signified by a beep. Waiting a few moments for the exhaust pump to clear any remaining smoke is a good idea, especially with wood, and will limit the build up of smells in the rest of the workshop. Remove your work piece, ensuring that all parts are cleared from the bed of the machine.

'''Power Down'''

The cutter is turned off using the key switch, then the air filtering system with the green rocker switch. Shut down the PC and double check that everything is left in a safe state for the next user.

'''Clean the bed of debris using the soft brush, then wipe down the bed using IPA and a cloth.'''

If you have been cutting particularly 'dirty' materials, most notable MDF and Ply which leave a sticky residue then you will need to use the course side of one of the oven pads and lots of 'elbow grease'. Residue on the bed can impact the next persons' job so please make the effort to clean up and leave the cutter as you would wish to find it.

Go away excited by what you can make and come back with lots more drawings!

== Power and Speed Settings ==

In due time we will try to build up a large sample stock of materials and record the values which work best. Here are the sample material tests we have so far:

<gallery>
File:Laser-schmoo-3mm-acrylic.JPG|3mm Acrylic
File:Laser-schmoo-10mm-acrylic.JPG|10mm Acrylic
File:Laser-schmoo-9mm-mdf.JPG|9mm MDF (note: do not cut MDF - see above!)
</gallery>

Settings to get you started:
*3mm Acrylic: Speed 12, Power 100, Corner power 100
*5mm Acrylic: Speed 6, Power 100, Corner power 100
*Acrylic shallow cut: Speed 30, power 50, corner power 50
*Etching acrylic: Speed 400, Power 50, Spacing 0.05

== Tips & Tricks ==

* If the laser cutter's user interface does not seem to respond/do what you want, hit "ESC" to return to 'normal mode'.
* The opaque white acrylic needs slightly stronger settings for surface cuts as they are not as visible as in the transparent acrylic (i.e., for similar effect you need a deeper cut). Otherwise seems to cut equivalently to transparent acrylics.
* If you want a tight fit of pieces or very accurate sizing, keep in mind that the laser beam has a width of just over 0.1 mm (maybe 0.11 or 0.12 mm). So all exterior cut lines should be offset by 0.05 mm; you can do this very easily in the LaserCutter Software with the "Offset" tool (units are in mm, so enter '0.05' and select 'Outer').
* The DXF file format stores values only (not values and units). The internal units in the LaserCutter are in mm. If you set your document's units to mm in the exporting CAD system it should work fine, but generally it is a good idea to have a piece of geometry of known length, e.g. a line 100mm long, or a box of known size around your design. This makes adjusting the scaling a lot easier.
* If you want to export a DXF from Inkscape (which is a great, free vector drawing package), then make sure you do "Object to path" from the Path menu for the whole object and then during the export stage, enable "use ROBO-Master type of spline output". This should make sure all the curves and so on work.
* There's now a page to help with Inkscape and our laser at [[Equipment/Laser_Cutter_Inkscape]]
* If the jog buttons (arrow keys moving the laser head around) are only moving the head in small single steps rather than moving it continuously, make sure that the jog step size is set to 0.0mm in the Jog Settings section of the menu.

== Fixing strange issues ==

* Etching doesn't work
** Lines are not closed. LaserCut usually warns you about this. Ctrl-a to select all, then Tools->Unite Lines (0.001 should be fine).
** Two copies on top of each other. Copies on top of each other "cancel out" any etching. Delete one copy.
** Test with Menu->Laser->Simulate

* LaserCut will not download to the laser cutter
** Check laser cutter isn't in a paused state
** Restart LaserCut on the PC. (We've not had any usb issues nor needed to restart the laser since upgrading the PC summer 2014).

* Laser cuts things out 2+ times
** Check you don't have two copies loaded on top of each other
** Check it's not set to cut multiple times in LaserCut (this setting is right of the Cut/Engrave/Speed/Power settings)
** Check the laser front panel says "001" at the bottom. If not, press right arrow until the number is highlighted, then down to adjust back to 1, then press return.

* Laser will only cut at the top right of the bed
** Download again with Immediate Mode ticked
** On laser panel, press return (I think?) then right twice (should select the bottom left option), then press return (I think).

== Material Stock ==
For the stock we hold, please see the [[Equipment/Laser_Cutter_Stock|Laser cutter stock]] page.

== Maintenance Log ==

For full log, see laser cutter wall sheet

'''Reactive Maintenance'''
* 15th Jan 2013, Simon Ford: Laser cutter not powering up, with switching on via key gives no activity whatsoever. No recollection of it cutting out during a job (Alexis), so assume it just stopped turning on at some point. Filter box and power sockets confirmed OK. Diagnosis: RCD in right back panel of Laser reset to off, no obvious reason why. Switching back on brought everything back to life OK.
* 22nd, Simon Ford; 29th, Nicholas - same again.

* Apr 2014, Mat Cook and Diana Probst: after previous changing of chiller water (Roger et al) the pump was complaining of lack of flow. Changed water and filtered, removed small blockage from rubber hose on laser tube.

* 16 Apr 2014, Toby and Diana: changed laser tube, refilled chiller. Laser cutter fully working.

* 25 Oct 2014, Mat and Diana mended lid spring brace. Cutter working fully.

'''Regular Maintenance'''

* 19 May 2014, mirrors cleaned, earthing wire on lid tightened. Diana (and Mat's screwdriver)
* 21 May 2014, cleaned lens with Mat Cook. Diana
* 02 Jun 2014, removed and cleaned laser bed
* 14 Sep 2014, cleaned lens and mirrors, realigned. Diana and Brian Starkey

* 30 Jun 2014 Fitted microswitches in series with the magnetic "lid closed" detector. Magnetic detector still in operation, but with additional cutouts in series. (ie Magnetic open OR left side open OR right side open).
Risk assessment: increase in lid safety because it's in series with existing system. Tested that each detector individually will cut out the laser. Low electrical risk (low voltage and not near fingers). Mechanical components designed to not be sharp / protruding overly.
This additional system can be bypassed by determined operators and the reliability of the exiting cutout system is unknown although presumed to be reliable. We feel that the microswitches are an additional safety layer and no existing safety system is compromised. We do not believe there is any additional "perceived safety" causing more risky user behaviour.
The microswitches are operated by plastic affixed to the lid. The position/depth of these may need to be adjusted with time.
