== What is in Makespace? ==

* '''[[Equipment|Our Equipment]]'''
* [[Equipment Status]] (experimental page; may not be accurate)
* [[Infrastructure]]
* [[Things and stuff]] --- locator for smaller items

== How does Makespace work? ==

The space is great for individuals wanting to experiment, startups or companies wanting access to prototyping equipment, companies in the business who can come and do training and provide services beyond Makespace, and groups that want space to meet. Anyone who could benefit from a shared space focused on making things.

At its core is a membership-based structure; the price of membership is £40/month inc VAT for full membership for 24/7 RFID access, or £33/month inc VAT for full student membership (no access outside of Cambridge university terms).

It is a community run space; see:

* [http://makespace.org Makespace Main Website]
* [[Induction|Membership and inductions]]
* [[Useful makespace info for Members]]
* [[Policies]] - ie how stuff works
* [[Latest member news]] - a great place to start if you want to find out what's been happening lately or what's coming up
* Non-exhaustive [[People|list of people]] currently or previously involved.

== Getting involved ==

* Some information about other groups around the world that may be of interest can be found on the [[Links|Links page]].

* Some projects may need external [[Service Suppliers]] for things we can't do in-house.

== Regular groups ==

There are regular meetings open to non-members on a variety of subjects. Or if not actually regular, at least repeated.

* [[Family Makers]]
* [[Raspberry Pi-makers]] and home automation
* [[Arduino and Cake]] --- now merged with Raspberry Pi and home automation group
* [[Robo-makers]] (is this still going?)
* [[Things that fly]] --- quadcopters etc (is this still going? might be summer only)

== Social Meetings ==

There are always socials - and meetups and other things! The canonical means of arranging these is via Meetup: http://www.meetup.com/Makespace Check out [[Events policy|how to run an event in Makespace]].

== Formal Meetings ==
There are write-ups of planning and member meetings at [[Makespace/Meetings | Meetings]].

== External meetings, conferences etc ==

We list some [[external events]] that may be of interest to Makespace members.

== Sponsorship and Donations! ==
we're grateful to the founding sponsors who helped set Makespace up. Most current running costs are met from membership payments but we gratefully receive any donations, however small, that can help with developing, running and improving Makespace for everyone. Contact management (at) makespace (dot) org. Thanks!

Events policy

2017-04-24T18:11:56Z

Markw:

== About this policy ==
Any Makespace member can book the classroom for events, talks, workshops, etc that are broadly related to making. Events must conform to this Events Policy. If you are a member, and have read this policy, contact the administrator or management to be added to Makespace's Meetup group, which is used for booking the space (as well as for enabling signups, if needed).

Related document: [[HostingSpeech|What hosts should tell people at the start of an open meeting]]

= Steps to run an event =

'''0. Be a member'''

'''1. Follow the rules below'''

'''2. Check at http://www.meetup.com/Makespace/events/ that the classroom is free at the desired time, and book your event there so others know it's happening and won't book the space at the same time'''

You can use meetup to advertise the event, or just use the Meetup calendar function to book the time. If your event is advertised by another group then just use the calendar (http://www.meetup.com/Makespace/events/); it gets confusing when there are two meetup events for the same meeting, and makes it hard to limit numbers to the maximum capacity.

State clearly which bit of space you are booking: Main room, Classroom, Workshop or Upstairs.

* If you're booking a meetup event, select the correct location (Makespace main room, Makespace classroom, etc).
* If you're just using the calendar, please state the location information in the event name.
* The classroom absolute maximum capacity is 60 seated, or 30 if you want tables; the main room holds around 100 standing. It is a good idea to limit meetup signup slots to reflect that.

Note: you'll need to have organiser role for the Makespace meetup group to be able to edit the calendar. If you're not, either ask on the Google group to be made one, or find someone who is already an organiser.

== General principles, or, how to host an event ==

* '''All members are welcome to organise an event at Makespace, and hosting an event is free of charge to members'''

* '''Booking of rooms is generally handled via the makespace Meetup group.'''

Say whether you are using the: main space; classroom; workshop; or cafe

* If you aren't a member and you want to organise an event in Makespace, you either need to persuade members to host your event (by asking on the google group), or become a [http://makespace.org/membership member] yourself!'''

* We strongly recommend that at least '''two''' members are happy to host an event, as this makes the event more likely to be a success.

* If you have questions on how to host an event, the place to ask them is the makespace [https://groups.google.com/forum/?fromgroups#!forum/cammakespace mailing list].

=== Notes ===

* '''For any event open to non-members, the usual rules about guests in the space apply.'''

* '''Event organisers/hosts are always responsible for what happens at events.''' In other words, the members organising the event are responsible for the people attending and must be ready to handle emergencies, escort them out in case of fire, and if anything goes wrong (kit is broken or stolen, etc) the member(s) running the event will need to deal with the consequences as they will be held responsible.

''If a member brings in a few guests to show them around, have a meeting, work on a project etc, that's not an event, because it's all people the member knows and is escorting in the space - that's normal Makespace stuff :) ''

'''Children''' attending the space should always be accompanied by a responsible adult; no more than 1 child per adult member or visitor (as it isn't always possible to supervise more than 1 child in a workshop situation).

'''If you are NOT the organiser of an event''' you should NOT let non-members into the space unless the organiser has requested it of you directly.

== If you want to run an event in Makespace and you are NOT a member ==

Only Members can host events, so if you want to run an event you'll need one or more members to be willing to act as hosts. You could ask on our [https://groups.google.com/d/forum/cammakespace Google group] to see if anyone is interested in helping you, but we can't guarantee that anyone will be.

Or, consider becoming a makespace member yourself!

== Event types ==

Events are either:

* Members only
* Open to the public (which may optionally include the opportunity to Meet Makespace, ie have a tour and ask questions about membership)

'''Events listed on Meetup.com/makespace should clearly indicate whether they are Public, Members-only, or Meet-Makespace'''. Not all public events are ones where non-members can come and see the space and ask questions about membership and we need to clearly indicate those!

=== Members only events ===

These events are organised by one or more members.

* because everyone attending is a member, things are fairly straightforward
* event may be anywhere in the space
* if most of any one room in the space will be used and it won't be possible/nice/easy for other members to do stuff in that room whilst the event is happening, then the event should book the room(s) in advance on the calendar.
* the event can be free or subject to a charge (the funds could pay for materials and/or a trainer's time or travel expenses etc, or could be donated to Makespace). If the event has a charge, the member(s) organising it are responsible for collecting the money and making any payments.
* The event can be open to all members or restricted to just some members (for example, only members who have been trained on the 3D printer; only a fixed number of members; only specific members for some other reason).
* '''No event should allow more than 100 people into the space at once.''' It may be useful to count people in on the door so you know when to stop admitting people.

=== Events open to the public ===

These events are organised by one or more members but non-members are able to attend.

* It's useful to run some sort of '''RSVP system''' so you aren't overwhelmed with people turning up unexpectedly. Whether you do or don't get an idea of numbers in advance, if more people turn up than the organisers or space can handle, the organisers MUST close the doors and not permit more people in.

* remember, if you're the sole organiser, you have to be there or your event can't take place! You might want to make sure you can notify attendees if you are ill or unable to attend at the last minute.

* We encourage events to be open to members if at all possible, and that members who happen to be in the space can attend events if possible. However we understand that sometimes this isn't possible, as some events may be restricted to just some members (for example, only members who have been trained on the 3D printer) or other limits may apply (such as a training event where the trainer can only work with up to 8 pre-booked learners, or a meeting is only open to people who have paid to attend, or where preparatory work is required).

* Events may be free or subject to a charge (which may be either formal, eg "£5 per person", or informal, eg "please chip in a couple of quid if you can"). ''It is totally fine and even good to charge non-members more than members.''

'''Numbers of guests'''

Depending on the number of people attending, there are requirements on how many members must be organising and attending the event.

* For up to 10 guests, one member can organise the event '''but we strongly recommend at least two members organise any public event''' because it's really hard to keep an eye on everything when hosting an event; for up to 20 guests, two members; for up to 30 guests, 3 members, etc.

* '''No event should allow more than 100 people into the space at once.''' It may be useful to count people in on the door so you know when to stop admitting people.

* If the space feels overcrowded, immediately close the front door and do not permit more people to come in.

'''Hosting a public event'''

* Non-members attending your event should be encouraged to read the Visitors rules (posted at the internal door of makespace (NB not posted quite yet)) and to sign in the Visitors Book (if we have one) and to sign in on any sign-in sheet (see below).

* Encourage non-members attending your event to take a Makespace card and consider becoming a member :)

* If there are more than 10 non-members present, the organiser should give a brief housekeeping intro at the start of the event, pointing out fire exits, and potentially also other useful info (toilet location, first aid or other safety information that may be needed). See [[HostingSpeech]]

* If your event is one where it's possible to Meet Makespace, please indicate that clearly. You'll need to either offer a tour before or after the main bit of your event (if it's something like a talk or demo), or have Members available to show people around throughout your event (if it's something like Maker Night). '''Note that this is time consuming and you should ensure you have plenty of Members involved in organising the event, so the event can happen as well as tours and questions!'''

'''Doors'''

* Beware - we often have non-members turning up FORTY minutes before an event is due to start! If you are NOT the organiser of an event, and you answer the doorbell, please DO NOT let people in unless the organiser has asked you to do so directly. Otherwise (and this has happened several times) an organiser who is still setting up ends up responsible for a bunch of non-members who have been let in far too early when the space isn't ready for them.

* The exterior front door should not be propped open unless you have a member waiting in the foyer at all times

* For larger events you may want to open the inner front door so that guests can let themselves out. DO NOT DO THIS if the exterior front door is propped open, or anyone could just walk into Makespace!

* there is an access token in the cafe which can be used to give access to the toilets. for big events you might want to relocate the token to the corridor just outside the cafe so anyone returning from the toilets can let themselves in. If you do that when your event ends YOU MUST BRING THE TOKEN BACK IN TO MAKESPACE.

== Big events and regular events and tracking attendance ==

Knowing who attends our events is important for Makespace to demonstrate its reach, which both meets the criteria of our bootstrap grant funding and is likely to unlock future funding opportunities. In particular we have a target to get 500 people each doing 6 hours of Makespace stuff!

So, if your event is 6 hours or longer, '''please ensure you have a sign in sheet where everyone signs in with their full name and signs to confirm they are attending a 6+ hour event'''. Once you have this sheet completed please scan it or email an electronic copy to management@makespace.org, so we can report to our funders.

If your event is less than 6 hours long but forms part of a series, for example, a course of 6 or more 1-hour talks or workshops, where you expect many people to attend the whole series, you will want to have a sign in sheet where it's easy to see how many events each person attended. You could use a matrix where each person signs in once and then ticks or signs for subsequent events. Again, once the course is complete (or you have lots of people who have done 6 hours of stuff) please scan it or email an electronic copy to management@makespace.org, so we can report to our funders.

The target is 6 hours in total of engagement and this can be made up of one 6 hour block, several shorter blocks of time, whatever.

== Publicity for events ==

* Events open to Members only can be advertised on the google group and/or on the Meetup group. It's essential that the event clearly indicates that it's members only.
* Events open to the public can be advertised on the Meetup group

You should only have one calling notice (i.e. Meetup event or similar) for each meeting:

'''If it's a Makespace event''', the calendar entry will happen automatically when you create the event on the Makespace meetup group (you need to be a limited owner of the makespace group to be able to control the more subtle aspects of event registration).

'''If the event is being organised by another group''', theirs should be the meetup group (or Eventbrite, or whatever else they use) publicising the event. The room in Makespace should be reserved by adding a calendar entry directly on the calendar tab of the Makespace events page. When you make the calendar entry, include the following information:
* The event name
* The start and end time
* Your name/contact details
* A link to the meeting's calling notice (if appropriate)

For more details see [[MeetupEvent]]

== Signage ==

If you are using the classroom or main space and you don't want other members wandering through make sure there's a sign outside to say what the event is and apologising for the inconvenience! If you are using the main space it's almost impossible for people not to wander through.

== Space ==

* Whichever room the event is held in should be returned to its usual layout after the event.
* '''Events are strongly preferred to take place in the classroom/meetspace''', especially if there's more than 10 people attending. Obviously some events may need to be in the main space (eg a 3D printer demo) but remember that use of the main space is more likely to inconvenience other members. (the same applies to events which use specific kit!) As a rule only general interest events which are agreed on list should use the whole main space. If in doubt use the classroom.
* Make sure tables and chairs don't block the fire exits or the paths to them. If you are using the main space, ensure other members can still move between the workshop, cakespace etc.
* Organisers are responsible for cleaning up after events and this should be done immediately after the event, not later in the day or the next morning. If you get food supplies in (e.g. pizza delivery to a hackathon) please take the packaging out to the large external recycling bins (outside the back door of the main space, and up the steps to your right) immediately after the event.

'''The classroom''' has a set of folding tables and stacking chairs, and a projector mounted to the ceiling.

'''Optionally we could alter this policy for all events to be in the classroom unless the google group or the directors agreed otherwise.'''

== Food and drink ==

* Makespace doesn't provide catering.
* Organisers can arrange food and drink, or use existing honesty box snacks and tea/coffee facilities.
* Alcohol can only be served at events with the prior permission of the Directors. This applies even if there happens to be beer in the kitchen.

== The Events calendar ==

We generally divide each day into morning/afternoon/evening and book time against these slots but more specific times can be used if that helps. Please try to allow at least 30 minutes between two events to let one clear down and the next set up.

Recurring events can occur:
* every day at the same time
* every week at the same time
* every month at the same time ''defined by day of the week'' (eg 7pm on the second tuesday of each month)

One-off events are also fine of course :)

For now we will use the [http://meetup.makespace.org/events/calendar/#calendar Meetup group] to schedule events. (We also have a Google calendar but that's not currently in use for community run events)

== Contention for space ==

In the first instance it's first come first served!

If you cannot find a good slot for your event, or there is already an event planned for the slot you want, contact the event organiser (this should be easy to do as they should be identified on the meetup.com listing for the event), and see if you can agree between yourselves who should have which slot.

if you cannot find a slot for your event (for instance, you need an evening slot every 2 weeks and they are all full), email the Google group, and we'll discuss what should happen. If the group doesn't quickly reach a decision, the Directors may arbitrate between groups and may make a final decision if needed.

Events are more likely to receive good slots if they:

* are for members OR are training/outreach for potential new makespace community members
* are makespace ish (see image at bottom of [http://makespace.org/index.php/space/principles/ Guiding Principles])
* will pay money to makespace for the event

If contention becomes endemic we will look at ways to manage this but we won't tackle this unless it's a problem.

== If events cause you problems... ==
If an event means you can't use the space or some kit you want to use, or otherwise is a notable inconvenience, or if people attending an event behave in a way which you feel is unsafe or abusive in any way, please let us know on the Google group or by emailing management@makespace so we can figure out if we need to alter this policy or take other action.

Markw:

Hello all,

Spring is here, and with it another roundup of news from Makespace.

== Report from the Science Festival ==

There were three Makespace events in the recent Cambridge Science Festival, all a great success. At our fourth birthday party and showcase, members of the public came round to see a range of recent members' projects on show and see some of our kit in action. There were lots of exciting things on show, so thanks to everyone who brought something or helped with the event in other ways. David's event teaching kids to program robots, and Sophie's knit-a-neuron event, were both fully booked and very popular, so thanks to them too.

As a result of these events lots of new people are aware of Makespace and there will hopefully be a steady stream of new members over the next couple of months, so if you are a trainer on any equipment, and have a couple of hours to spare, please think about running some equipment inductions.

== Run an event at the Festival of Ideas ==

On a related note, the Cambridge Festival of Ideas will run from 16-29 October 2017, focused around the arts, humanities and social sciences. If you would be interested in running an event at Makespace for the Festival, get in touch. The closing date for submitting proposed events is 29 May.

== Free SolidWorks demo ==

Cadtek, who are a SolidWorks reseller, are running a free introduction to Solidworks at Makespace on Wednesday 24 May, 10am-3pm. Sign up [https://www.meetup.com/Makespace/events/239035402/ here].

== Classroom update ==

The classroom has recently been repainted, quite a lot of junk removed - thanks to many members for working on this. In addition an electrician has installed trunking with power sockets around the walls. Please run interesting makery events there!

== Lease update ==

We are hoping to sign a new lease with the University in the near future. The Directors have been working to address a number of health and safety concerns to make this possible. This work is now mostly done, with a small number of outstanding matters (concerning e.g. fire procedures, fire door auto-closers, gas bottle permission & notice, and storage). The legal negotiations are complete and the University will sign the lease when the outstanding actions are closed.

Please help keep on top of safety by keeping the space clean and not storing materials where they may obstruct fire exits or constitute a fire or safety hazard.

== Darkroom plans ==

We expect that the signing of the lease will finally enable us to add a darkroom to Makespace. There will be a meeting to discuss the plans for a darkroom on Wed 26 April at 7.30pm in the Classroom. If you'd like to get involved, sign up [https://www.meetup.com/Makespace/events/239011618/ here].

== Safety, fires and lasercutters ==

A small fire was started by one of the lasercutters recently while cutting 5mm perspex sheet. The member concerned immediately hit the emergency stop and removed the workpiece, and there were no further problems. Our lasercutter training emphasises that the cutters must be supervised at all times, and this incident shows why! Please remember that fires can start with any material, and be vigilant. More generally, remember that lots of our equipment can be dangerous if wrongly used, and follow the safety procedures you have been trained in. If you aren't sure you remember them, ask the equipment's trainers or owners. Thanks to all our trainers and users for continuing to keep Makespace safe.

== Science Makers and other happenings ==

A reminder that many wondrous things happen at events in the Classroom that you can sign up for. See the Meetup [http://www.meetup.com/Makespace/events/ calendar] for a list. One regular is the monthly Science Makers meetup, where at [https://www.meetup.com/Makespace/events/239035726/ May's meeting] you can come and build a spectrometer.

Dear Makers,

Makespace is having a public birthday party, open evening and show-and-tell on Thursday 16 March from 6.30pm. It's been published in the Science Festival programme so there are likely to be quite a few visitors. You can help!

* Do you have something cool you've made at Makespace that you could bring to show visitors on the 16th?
* Could you help with demonstrating a piece of kit? It would be good to have demos of lots of different things.
* Are you available to be around on the evening to help with showing people around and answering questions? Or earlier to help set things up?
* Or is there some other way you could help out?

If the answer to any of these questions is 'yes', please let us know.

* Please tell your friends and relations about the event, and tweet and facebook it to smithereens!

== Classroom tidying this Saturday ==

There will be some tidying and hopefully painting in the Classroom this Saturday, 4 March, from 2pm. If you are free, please come and lend a hand.

Dear all,

There will be a [https://www.meetup.com/Makespace/events/235905503/ Makespace Christmas Party] on Tuesday 20 December from 7.30pm. Come and make those last minute Christmas gifts and decorations, bring some festive food or drink to share, and bid farewell to those foolish members who are going away for Christmas while you stay and have the run of the place to yourself or vice versa. Meet new members and old timers and get ideas for projects to make in the new year.

This will replace the normal monthly social on the last Thursday of the month.

Other news from Makespace is below. Note in particular the Trove survey - please take five minutes to respond!

== Trove survey ==

The idea has been floated in the past of converting the Trove to more workshop space, perhaps adding a mezzanine and retaining some storage
as well. We'd like to hear how members are using the Trove and what they'd like to see there. Please take five minutes to complete [https://www.surveymonkey.co.uk/r/LC8QY6V this survey] - all answers are anonymous.

== Network improvements ==

We have been making a number of changes to the network and internet access at Makespace. Over the last 6 months, we have upgraded the WiFi access in the space to provide more reliable WiFi coverage of the Classroom and main space - this supported by a more capable EdgeRouter and firewall and most recently, an upgraded Virgin Media broadband connection.

The network is now monitored from both outside and inside Makespace so that we know when something has gone wrong, know how loaded the network is (we recently had over 100 devices simultaneously connected inside the network) and what it is being used for.

The latter aspect has made us aware that there are a small number of members who are using the Makespace network for P2P sharing and torrenting activities. In addition to reducing network performance and availability for other users, these activities are often associated with illegal downloading and could result in Makespace being fined and prevented from operating an internet connection. The Makespace management will take all neccesary steps to prevent this from happening.

== Theft prevention ==

For some time Makespace has been experiencing a series of thefts of small amounts of material, equipment and cash from the honesty boxes in the space and, more recently, from the office.

After the most recent theft, a decision was taken to setup a CCTV camera covering an area inside the office and not accessible to the general membership. Withing 6 hours of installing and commissioning the camera a (now former) member was observed breaking into a filing cabinet. The matter has now been handed over to Cambridgeshire Constabulary for investigation and probable criminal prosecution.

A small number of positive outcomes did emerge from the spate of thefts:

* The Makespace community now has a bank account that both keeps funds safe/secure and makes buying stock for equipment and the kitchen much easier

* The funds in the various honesty boxes are regularly trimmed back and moved to the bank account

* Makespace now takes ePayments - including contactless! These funds go directly to the community bank account and iZettle keeps track of what the money was used to pay for.

To ensure that we don't have a shortage of materials and snacks, Makespace Cambridge Ltd. has replace the stolen funds. While we hope and expect that this is the end of the problem, remember that, of course, anything left at Makespace is stored at the owners' risk.

== Fire safety and Health & Safety ==

Most of you will appreciate the considerable improvements made to the space in the last few months. Many thanks those members who put in long hours and so much effort cleaning, organizing and building. Part of the reason for doing this has been to bring Makespace closer to full compliance with the Fire and Heath & Safety standards set by the University, who are our landlords. Please help us to:

* Manage fire doors - if not kept open by an auto-release device that will allow the door to close if the fire alarm sounds, then keep the door closed. Do not jam or prop any fire door open.

* Look for and help remove Fire and H&S risks

* Keep the bins emptied and avoid having excess material lying around or stored in the space

* Remember that in the case of a fire your primary responsibility is to get yourself, and (if possible without additional risk to yourself) others, out of the building and then call the fire service.

* We still have some work to do to be fully compliant and will be looking for regular members to attend various fire safety training events.

== Date for your diary ==

Makespace's fourth birthday will fall during the Cambridge Science Festival, and to celebrate, there will be an Open Evening and birthday party on the evening of 16 March. More details nearer the time, but save the date - bring along something you've made to show, or you can help out in other ways before or on the day, such as helping get the space ready or showing visitors around.

Dear all,

Makespace is holding an Open Day on Saturday 29 October. Please tell your friends, tweet about it, Facebook it to smithereens, and come along yourself - bring a current or finished project to show off, or demo some equipment, or just be on hand to talk to people about Makespace.

Also, don't forget there is a community clean-up the previous weekend, on Sunday 23 October. Details of both events and other news is below.

== Forthcoming events ==

=== Cambridge TV, 20 Oct ===

Cambridge TV will be in the space from 4-8pm this Thursday, 20 October. They hope to get material for one and possibly two items about Makespace (for different programmes). They'd love to meet any members who are happy to talk on camera about a project or their use of the space, or be filmed using equipment. Of course the space will also be open as normal and there's no obligation to be filmed!

=== Grand clean-up, 23 Oct ===
Come and help clean, tidy and organise the space, from 11am on Sunday 23 October. Free pizza for all helpers! Just turn up or sign up [http://www.meetup.com/Makespace/events/233797150/ here].

=== Open Day, 29 Oct ===

There will be an Open Day on Saturday 29 October, 12-6pm. Please publicise it and come along if you can - for this to be a success we need lots of visitors and lots of members to help demonstrate equipment, show projects and point the way to the toilets :-) The event is part of the Crafts Council's Make:Shift:Do programme, so it is one of over 30 on the same day at maker spaces across the country. Jo Brook is organising the day, and if you are bringing something to show or can demo some equipment it would be great if you let her know. Please also e-mail photos of things you've made here! More details
[http://www.craftscouncil.org.uk/listings/makeshiftdo-at-makespace-cambridge here] or
[http://www.meetup.com/Makespace/events/233532721/ here].

== Makespace in the media ==

=== MagPi 50 ===

The MagPi (the Raspberry Pi magazine) recently celbrated its 50th issue and the 10 millionth Raspberry Pi with a list of the 50 best Pi projects ever. Not one but two Makespace projects made the list - Tom Oinn's robot Triangula, and Brian Corteil's wonderful Digital Zoetrope. You can download the whole issue [https://www.raspberrypi.org/magpi/issues/50/ here].

=== Smartbell on TV ===

Makespace regular Jose Chitty and his business partner were interviewed on Cambridge TV about their startup Smartbell, which makes smart wearables for cows. You can see the interview at the link [http://www.cambridge-tv.co.uk/cambridge-entrepreneurs-ep16-smartbell/ here] (including a shout-out to Makespace at 03:10).

== Storage and fire risk ==

A recent Health and Safety inspection highlighted the problem with lots of junk lying around - both as a fire risk and where it could impede people leaving in an emergency. Jonathan Woolf has done heroic amounts of work clearing out junk, putting up new racking, and throwing things away. By an amazing coincidence the place is also looking much nicer as a result.

Please can you remove or move anything you have in the hallway that is not in your named box. Anything still there in a few weeks may be unceremoniously thrown away. If you don't have a box and need one, get in touch! There will be more racking going up soon so there will be space for everyone who wants one to have a box.

== Reminder: answering the door ==

Please ALWAYS follow the rules when answering the door. If someone wants to come in who isn't known to you, you are under no obligation to let them in. If you do, *they are your guest*, no matter how much they tell you they are a member who has forgotten their fob. You must not leave the space while they are still in it.

It is up to you to decide whether to answer the door when in the space, but if you are expecting visitors, please do answer it, rather than waiting for someone else to let your visitors in, unless you are running a machine that you really can't pause or leave.

Markw: Created page with "Dear all, Here's the latest news from Makespace. == Forthcoming events == === Clean-up, Sun 23 October === It's about time we had [http://www.meetup.com/Makespace/events/2..."

Dear all,

Here's the latest news from Makespace.

== Forthcoming events ==

=== Clean-up, Sun 23 October ===

It's about time we had [http://www.meetup.com/Makespace/events/233797150/ a big clean-up], so come along from 11am and help sweep, clean, tidy, arrange, and throw away. Thanks in advance for your efforts, which will be rewarded with pizza.

=== Open Day, 29 October ===

There will be an [http://www.meetup.com/Makespace/events/233532721/ open day on Saturday 29 October] from 12 noon. Activities, exhibits and helpers are sought! Have you made something you're pleased with that you'd like to show off? Can you help demo a piece of kit on the day? Or would you like to just generally help out? Contact Jo Brook to get involved.

== Equipment ==

=== Electronics owner ===

The electronics workbenches are well used but not so well looked after. They have only one owner at the moment, Rob K, who would welcome help in the form of additional owners. If you are interested, e-mail electronics (at) makespace (dot) org.

=== CNC owners/trainers ===

There are quite a lot of people asking to be trained on the CNC router. But at the moment, only Robin is running inductions, and he can't keep up with demand. Can anyone else take on doing some training? You should have used the router but don't need to be an expert. Robin or another owner can meet up and go over how to run an induction with you.

=== Wood lathe open for business ===

The wood lathe is now commissioned and its new owners are running inductions. Check [http://www.meetup.com/Makespace/events/ Meetup] or ask on the [https://groups.google.com/group/cammakespace mailing list] if you'd like to be trained.

== Bits and bobs ==

=== Adjustable height table ===

At the suggestion of the city council's Accessibility Officer, we've got an adjustable height table, which is now in the bank of tables in the main space. There's a plastic cap at each end (please don't lose them) which, if removed, reveals a crankshaft. There's a crank handle (don't lose this either) in the drawer of the adjacent desk.

=== Honesty boxes ===

Cong kept some records for the kitchen honesty box which revealed that, unfortunately, there was money regularly going 'missing'. Replacing the box with a locked box with a slot seems to have fixed this problem. The other honesty boxes will shortly also be replaced with lockable ones. This does have the downside that it is not possible to take change. Apologies for this. If you have a suggested solution, please shout - meantime, remember to stock up on change when coming in to Makespace.

=== Community bank account ===

There is now a bank account for community funds from the various honesty boxes. If you want to buy consumables, get the agreement of a relevant owner (who should check that the relevant kitty has enough funds as well as that the purchase is sensible), and then e-mail signatories (at) makespace (dot) org to arrange repayment.

=== WEEE disposal ===

Cambridge Computer Recycling recently came and collected a huge supply of waste electrical and electronic equipment (WEEE). WEEE can't be thrown in the bin so it's great that they do this - they do it without charge as a commercial venture and then recover as many parts as they can. Apparently they have a warehouse of unlikely and elderly components, so if there is something you're looking for you could try contacting them! If you do have any WEEE to get rid of at Makespace, please find someone who can put it in the office, and when another pile has built up we'll call them back.

Dear members,

Here is the latest roundup from Makespace. Are you sitting comfortably?

== Recent events ==

=== Radio interview ===
Jonny Austin, one of the founders and directors, recently spoke about Makespace to local community radio station Cambridge 105. It's a nice interview - have a listen, or pass it on to such of your friends, relations and Twitter followers as may want to know more about Makespace. It starts at 28:02 [http://cambridge105.fm/best-of-the-guests-18-07-2016/ here].

== Forthcoming events ==

=== Game jam, 27-8 Aug ===
Want to help to design and produce a game in a weekend? If that sounds interesting, [http://www.meetup.com/Makespace/events/233350049/ this] is probably for you.

=== Continuing education ===
The University of Cambridge's Institute of Continuing Education offers various part-time [http://www.ice.cam.ac.uk/courses/certificates-and-diplomas postgrad courses]. The deadline for 2016-17 courses is 5 September. They are not particuarly maker-ish but might interest some members - especially the Astronomy diploma, judging by the number of bits of astronomical kit made here from time to time.

=== SME Growth challenge taster event, 12 Sep ===
This programme at the Judge Business School, on growing small businesses, previously had a closing date in August. But it seems there are still places as the JBS is now offering [http://insight.jbs.cam.ac.uk/events/sme-growth-challenge-taster-session-and-networking-event/ this free 'taster' and networking afternoon], which might be of interest whether or not you are thinking of joining the programme.

=== Serious impact===
[http://seriousimpact.co.uk/ More free support] for local startups including mentoring, workspace, networking etc is available from this non-profit scheme funded under the Local Enterprise Partnership.

Quacky Races, 18 Sep: This might interest some members - [https://www.facebook.com/events/1797500730485419/ enter a competition] to make a sustainably powered duck.

== Equipment ==

=== Knitting machine ===
The knitting machine, after a period of neglect, has had some tender loving care and some new owners, and training is available. It can take your computer-specified design and help you turn it into a piece of knitting. If you would like to be trained, contact knittingmachine(at) makespace (dot) org. Note that the training is one-to-one and takes about two hours, so please only ask for training if you are going to use the machine.

=== Wood Lathe ===
The wood lathe also has new owners and the commissioning process is just being finalised. Training for new users will be offered soon! Watch or ask on the mailing list for details.

=== Jewellery books ===
Following a recent training session for new users of the fine metalwork equipment, we've acquired some books on jewellery making, which trained users might want to use to refresh their memories or get new ideas. They're currently on the fine metalwork bench.

== Odds and ends ==

=== Financial hardship ===
Following a long discussion online and a proposal from an open meeting, the Directors have decided to trial a half-price membership rate in cases of genuine financial need. This will help towards realising one of Makespace's guiding principles, of being accessible to all regardless of means. To be eligible, members or prospective members will need to contact membership (at) makespace (dot) org and sign a declaration of financial hardship, and to renew this declaration (if it is still applicable) at three-month intervals.

=== First Aid ===
Jenny recently ran an introduction to First Aid for Makespace members. It was very useful and she is happy to run it again if there is demand. Shout on the mailing list if you'd be interested. Speaking of First Aid, please remember that we need to keep an accident record, so if you have an accident in Makespace, however minor, you must report it to management (at) makespace (dot) org. If you use any First Aid supplies, or if it seems something is missing or running low, please (also) report it to firstaid (at) makespace (dot) org.

=== Organising events ===
Remember that as a Makespace member you can use the classroom, and/or equipment where practicable, to organise events, meetings, workshops etc which are loosely related to making. See the [http://wiki.makespace.org/Events_policy Events Policy] for details.

When the classroom is booked for a meeting or event, it is not available other than to attendees of the event. All bookings are noted on the [http://www.meetup.com/Makespace/events/ Meetup calendar].

Minutes of members' meeting 21 July 2016

2016-08-23T08:38:24Z

Markw:

Thanks to all those who came to the Makespace members' meeting last Thursday. There were over 20 members present and a lot was discussed (and many kilos of pizza eaten). There are full notes below, but please note in particular:

OWNERS WANTED for WOOD LATHE and KNITTING MACHINE!

The wood lathe has no owners, and the main owner of the knitting machine will be leaving soon. If you would like to use either of these machines and are prepared to help keep them at Makespace, please get in touch. Ideally there will be 2-3 owners for both machines, so you will not be on your own. You do not already need to know how to use them, but you must be prepared to commit some time to help manage them. If no owners come forwards they will be disposed of. For details see items 3 and 4 below.

== 1. Finances ==

The board gave a presentation on Makespace's finances, income and budgeting, and the possible options for a 'Makespace 2.0' when the lease on our current premises expires (expected in 2019).

== 2. New 'exec' ==

There used to be something called the 'Exec' (it hasn't been active recently), a group of members who'd volunteered to take on extra responsibilities for helping to run Makespace. The board would like to restart something similar, with members taking on specific responsibilities and associated budgets - so that, for example, spare parts for a machine that are within a set budget can be bought without needing to wait for a director's authorisation. More details will be announced soon. It was suggested at the meeting that 'Exec' is not a very good name as it sounds remote and similar to a board of directors - other names suggested were 'Co-ordinators' or 'Facilitators'.

== 3. Wood lathe ==

Despite calls on the mailing list no-one has come forward to help 'own' the wood lathe. It was agreed that, if we are to keep the wood lathe, two new active owners are needed by the end of August. If two owners have not come forward by then, we will ask Kim (who donated the lathe) to take it back. At present it is just occupying space that we could use for other equipment.

Volunteers to own the lathe would be welcome. The job of an owner includes getting the machine commissioned, putting a training programme in place, and dealing with problems as they arise. Previous lathe experience would be great but is not necessary as someone can be found to train you if you volunteer.

On a few occasions previously people have volunteered to own the wood lathe but then left or become too busy, so it was also agreed that if owners do come forward, we will look again in December. If there are no active owners then, we will take that as a sign that there is not enough sustained interest in wood turning and will dispose of the lathe.

== 4. Knitting machine ==

The owners of the knitting machine are Tom Myers and Rachel Rayns. Rachel is now very busy and Tom is leaving the country at the start of September. However, having recently finished exams he has spare time at the moment and is keen to find and train up new owners, as well as to train up any other members who would be interested in using it.

If you'd like to be trained on the knitting machine, ask on the [https://groups.google.com/d/forum/cammakespace Google group]. If you would be prepared to become an owner and help keep it running, please get in touch or e-mail Tom directly at knittingmachine (at) makespace (dot) org.

== 5. Dark Room ==

Our lease is being renewed and we've been offered the small space adjacent to the classroom in addition to our current space. It's small but there would be room to create a dark room, for creating photographic screens for screenprinting and potentially also for traditional development of photographs. Some members have volunteered to arrange this and it was enthusiastically agreed to by the meeting.

== 6. Community account ==

It was unanimously agreed to set up a bank account for the members' community, to handle money that is used to buy consumables and repaid through the honesty boxes (for food, laser stock, etc). This will have many advantages over the current system of keeping all the money in cash. The account will be opened with the Metro Bank with Mark Wainwright (the administrator), Jonathan Woolf and Cong Cong Bo as signatories. As a matter of policy no signatory will authorise a payment over £200 without agreement from another signatory, or make any expenditure that would lead to an overdraft. A spreadsheet will keep accounts for the different honesty boxes separate.

This will mean we have better tracking of how community money is received spent, can repay for expenses by bank transfers, and do not need to have cash kept on the premises. The account is free to operate.

== 7. Other business ==

=== Lathe ===
The owner of the Myford metal lathe (which has been on long-term loan to Makespace) plans to sell it. After discussions among the directors and lathe owners and on the list, the replacement decided on is a [http://www.warco.co.uk/metal-lathes-metalworking-lathe-machine/26-gh1322-gh1330-lathe.html Warco GH1330] with digital readout.

=== Tiered membership ===
A recent open meeting made a proposal for trialling a low-cost membership for people experiencing financial hardship. This is with the directors who will make an announcement soon.

=== Woodworking ===
One member was keen that we should have more woodworking capability and offered to make some suggestions for how this could be done without needing much more space.

=== Tell the world ===
A PLEA: If you do something great at Makespace, please tell the world about it! We are not good at this but it is important, especially as we look for support for a 'Makespace 2.0' when we have to move. As a minimum, it would be great to tweet a picture of your Cool Thing to [http://twitter.com/cammakespace @cammakespace on Twitter]. If anyone would like to co-ordinate a more sophisticated way of documenting the many amazing things that come out of Makespace, please volunteer!

Thanks to all those who came to the Makespace members' meeting last Thursday. There were over 20 members present and a lot was discussed (and many kilos of pizza eaten). There are full notes below, but please note in particular:

OWNERS WANTED for WOOD LATHE and KNITTING MACHINE!

The wood lathe has no owners, and the main owner of the knitting machine will be leaving soon. If you would like to use either of these machines and are prepared to help keep them at Makespace, please get in touch. Ideally there will be 2-3 owners for both machines, so you will not be on your own. You do not already need to know how to use them, but you must be prepared to commit some time to help manage them. If no owners come forwards they will be disposed of. For details see items 3 and 4 below.

Markw: July members' meeting

Latest member news 14 July 2016

2016-08-23T07:22:04Z

Markw: Created page with "Dear all, Here is another round-up of news from Makespace. Please note especially the members' meeting on Thursday 21 July. This will be an important opportunity to hear from..."

Dear all,

Here is another round-up of news from Makespace. Please note especially the members' meeting on Thursday 21 July. This will be an important opportunity to hear from the board and make your views heard on a variety of subjects. It will also take the place of the normal monthly social for July. Please come along if you are free!

== Members' meeting ==

As announced last month there will be a [http://www.meetup.com/Makespace/events/231694752/ members' meeting] next Thursday, 21 July, at 7.30. This will be both an opportunity to meet fellow members and discuss Makespace (and eat pizza). There will be a presentation by the the board on Makespace's organisation and finances, and discussion of any subjects anyone would like to raise. Some probable subjects for discussion:

* Exec: the board would like to breathe new life into the idea of a Makespace 'Exec', of members who volunteer to take on part of the running of Makespace. We'd like to establish clearer individual exec responsibilities and budgets.

* Wood lathe: There have been repeated calls on the mailing list for interest in the wood lathe but no-one has come forward to get it commissioned, working, users trained up, etc; there does not seem to be much interest in it. This meeting could decide to get rid of the wood lathe to make space for other equipment.

* Dark room: Our lease is being renewed and we have been offered the small space adjacent to the classroom. Some members have offered to use it or part of it to set up a dark room - come and discuss or hear more.

* Bank account: It would be good to open a bank account for community money (such as cash from the honesty boxes for the kitchen and lasercutters). This probably won't need much discussion but we need a formal meeting decision to show to a bank.

If you have anything you'd like added to an agenda please get in touch.

== Forthcoming events ==

=== First Aid ===
Our First Aid supremo Jenny Molloy is running an [http://www.meetup.com/Makespace/events/232368448/ introduction to First Aid] on 1 August. This is not an offical training course so there is no certificate, but Jenny is an experienced First Aid trainer and it will be good to have more members who know a bit about First Aid if the need arises. If the course is popular, Jenny has offered to run another session.

=== Hacklab courses ===
[https://www.thehacklab.uk Hacklab] are running short courses over the summer (some of them in Makespace) for people aged 8-16. The courses cover various aspects of making and coding, and you can sign up for one or two days or a week. There's a 10% discount for Makespace members if you use the code MAKESPACE10. See.

=== SME Growth Challenge ===
The Cambridge Judge Business School is running [https://www.jbs.cam.ac.uk/entrepreneurship/programmes/sme-growth/ this programme] to develop the management capability of small and medium-size enterprises. It will run in September and the deadline for applying is 1 August.

== Recent events ==

=== Megaprocessor talk ===
James Newman gave a well-attended talk on the Megaprocessor - the microprocessor he has been building from scratch out of hand-soldered transistors. If you missed it (or even if you didn't) you can see some pictures and more info at [http://www.megaprocessor.com www.megaprocessor.com].

=== Dorkbot ===
Another entertaining recent talk was a Dorkbot meeting showcasing various projects on the intersection of art, design, science and engineering - including a digital zoetrope and a robot artist. For future events follow [http://twitter.com/dorkbotcam @dorkbotcam] on Twitter.

== Waste wood etc ==

Diana and I and a few others have thrown away the huge pile of rubbish in the corner by the back door. If you have rubbish, do not leave it there - please throw it away. The main bins are just outside the back door - wood goes in the 'General waste' bins.

We used to have an arrangement with a company that would make regular collections of waste wood which they could recycle, but they went out of business some time ago.

== Internet connectivity ==

Thanks to heroic efforts by Adrian, Lee, and others, we hope that the problems with internet connectvity are mostly a thing of the past. There are now two reliable WiFi access points, one in the classroom and one in the main space. Both have 2.4GHz and 5GHz channels - you can connect using the generic 'Makespace' network name, or use 'Makespace-2G' or 'Makespace-5G' if you are finding one channel better for any reason. There are also improvements planned to enable easier access to the printers, etc. See Adrian's [https://groups.google.com/forum/#!topic/cammakespace/kDK6vWoQ-qU full message] on the Google group.

There are still some problems with the cable modem, which are being addressed. The networking equipment has been partly moved down from its high cupboard, so it can be worked on more easily when needed, and we are exploring the possibility of a single button "Internet, repair yourself!" fix as well as an auto-failover to a secondary internet connection. Meantime do shout if you have any problems.

Hello! we hope you're enjoying the sunshine but don't forget to come and make things too. Here is the latest news from Makespace.

== Members' meeting ==

It is quite a while since there has been a Makespace Members' Meeting, and it seems like a good time to have another one. So this will be held on Thursday 21 July, at 7.30pm, in the Classroom. This is a good opportunity to raise questions to the directors, discuss what is working well and what could be changed, thrash out proposals for new equipment, as well as meet fellow members and eat pizza. This meeting will replace the July social which would normally be on the 28th.

All members are welcome, and there is no need to sign up, but for estimating quantities of pizza it would be helpful to do so [http://www.meetup.com/Makespace/events/231694752/ here].

If you have any items you'd like added to the agenda for the formal part of the meeting, please send them to admin@makespace.org. You may wish to discuss them in advance on the Google group to enable everyone to contribute.

== New director ==

We are very pleased and lucky to be able to welcome Ward Hills onto the Makespace board, filling the void left by Laura's recent departure. Ward is a director, entrepreneur and investor who is actively involved with a number of technology start-ups. His interests include self-driving vehicles, remote sensing, rapid prototyping, signal processing, and more. He is an Entrepreneur in Residence at Cambridge University's Judge Business School.

Ward first joined Makespace in May 2013 to bring his daughters to Family Makers events, and has since become a familiar member of the community. He is currently collaborating professionally on various projects with partners that he's met through Makespace, and in his spare time is building a Raspberry-Pi-based telescope out of parts printed on the Ultimakers and some bits of bathroom tubing.

Ward says: 'What I love about Makespace is the attitude people have, that there's nothing that isn't possible.' Ward's management expertise will help keep Makespace on a secure and sustainable footing and ensure that even fewer things are impossible. He becomes the fourth member of the board, alongside Jonny Austin, Simon Ford and Adrian van den Heever.

== Forthcoming events ==

=== Megaprocessor talk, June 9 ===
James Newman has built a 16 bit processor from scratch - out of transistors. It's featured in the Register which noted that the finished circuitry will weigh about half a ton. He will be giving a talk on how and why he did it on June 9 at 7.30pm. All welcome but please [http://www.meetup.com/Makespace/events/231296582/ sign up].

=== Building a business, 16 June ===
A free morning event at the [http://hauserforum.com Hauser Forum], the University's centre for entrepreneurship. [https://www.eventbrite.com/e/b3-at-the-hauser-forum-tickets-25905181094 Booking required].

=== Startupbootcamp IOT accelerator ===
Startupbootcamp is running [http://www.startupbootcamp.org/accelerator/iot-connected-devices/ an accelerator programme] that provides IoT hardware startups with $15K in cash and mentoring, partners, manufacturing support, etc. It is in London and runs for three months from September. The deadline for applications is 13 June.

== Contacting Makespace ==

If you have an administrative problem or query, contact admin (at) makespace (dot) org. Mark, the administrator, will be away for two weeks at the end of June but the admin@ e-mail address will still be monitored (anything sent to Mark's personal address, and other non-urgent queries, will wait till he is back). For any concerns or problems about the space, purchase requests, etc, as usual contact management (at) makespace (dot) org.

== Reminders ==

=== No alcohol ===
Please remember that Makespace's rules do not allow alcohol in the space at any time, except at events (normally including the monthly socials) where it has been explicitly authorised by the Directors. Machinery must never be used after drinking alcohol on or off the premises.

=== Storage ===
Space for the boxes is running tight, so if you have anything stored on the shelves, please ensure that it is limited to one standard 35-litre box. If you do not have a box and need one, get in touch.

Larger projects that are being actively currently worked on may be stored temporarily in the Trove, if there is space for them. Anything stored in the Trove should be clearly marked with your name, a phone number or e-mail address and a date by which you expect it to be gone. Anything unmarked in the Trove is up for grabs for another project, so make sure your label is securely attached, otherwise someone might cannibalise your world-changing invention and turn it into a bit of their latest robotic chocolate teapot.

== Data protection ==

In response to a recent question about member's personal data and the UK Data Protection Act (1988): Makespace is committed to and compliant with the requirements of the act (and will be making all necessary changes over the next 24 months to ensure that we will be compliant with the act's pending replacement - the General Data Protection Regulation). Makespace only collects information about and from you that is needed to manage and operate Makespace Cambridge Ltd. Most of this personal data is managed directly by Makespace. To meet the UK/EU/International requirements needed to accept payment by credit card, Makespace makes use of a PCI-DSS compliant merchant service provider to process card payments - Recurly. In order to keep your credit card data safe, Recurly's data security standards meet and in most cases exceed industry requirements. To process the periodic card transactions and provide Makespace with the service it requires, Recurly transmits and stores your credit card and necessary associated information to its PCI-DSS compliant server infrastructure in the USA. Recurly does not store any additional personal information about members on behalf of Makespace.

Markw: Remove ex-members from listed owners

{{RedTool}}

[[Equipment|Equipment]] / WoodLathe

[[File:??.jpg|thumb|420px|right|Our woodworking lathe]]

= Summary =

We have a woodworking lathe kindly donated to us on indefinite loan by Kim Spence-Jones. It is a quality machine in fair condition but it is capable of causing severe injury so it must only be used by those trained to operate it safely. The 'owners' are responsible for training new users and ensuring that it is maintained in a safe condition.

=== To do before it's usable: ===

* Fit emergency stop switch, -- '''DONE'''
* and safety cut-out on pulley guard. -- '''CONSIDERED UNNECESSARY'''
* Re-wire/tidy cable grommet/re-PAT-test -- '''DONE'''
* Clean off rust, and re-paint as necessary -- '''DONE'''
* Find permanent location and bolt down -- '''LOCATION FOUND, HEAVY BASE CONSTUCTED'''
* Risk assessment -- '''DONE'''
* Training course syllabus
* Add essential extra tools & accessories
* Acquire Tormec wet grinder?
* Document the speed settings

''(The lathe is now usable by owners)''

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

= Using the woodworking lathe =

The lathe is a wood turning lathe capable of machining circular cuts in material up to about 30cm (12 inches) in diameter for bowls (20cm for spindles) and about 125cm (4') long. At the moment we only have centres; faceplates can be used, and will be added to the accessories later. The lathe is solidly built so with care excellent results can be obtained. We currently have three lathe tools, which should allow most basic woodworking operations to be undertaken.

This lathe has five speeds, it cannot be run in reverse.

== Safety ==

The workpiece is spun at high speed with great force. Clothing or hair caught in the workpiece will not slow the motor! Before starting take time to check there is nothing likely to be caught in the machine.

Chips can be thrown off the workpiece at high speed so eye protection is important.

Unbalanced workpieces can shake loose and fly in any direction. Take care when mounting your job.

To achieve real safety operator attitude is key. Trying to achieve unrealistic goals in limited time is the prime cause of accidents. Please take the time to plan your work and gain sufficient knowledge to perform it safely.

Dust from many woods can cause allergic reactions in some individuals, and some woods have been identified as carcenogenic. There is a book in the library ("Wood for Wood Turners" by Mark Baker) which documents possible health risks for 150 different woods.

The live centre is sharp. When you're not using it, take it out so you don't spike yourself with it.

== Owners ==

The owners are experienced users who have volunteered to ensure members know how to safely operate the lathe before they become approved users. Their next responsibility is to ensure the lathe is in a safe usable condition. Time permitting, they will advise users on how to make best use of the lathe.

So far the owners are;
* [[user:Kim_SJ|Kim Spence-Jones]]
* [mailto:m.greenwood70@btinternet.com Matt Greenwood (Matt the Carpenter)]
* Louis Kovalevsky

== Training ==

<div style="background:#FADADD; border:1px solid #FFC0CB; padding:5px">
THE LATHE IS PROVISONALLY APPROVED ONLY FOR USE BY OWNERS. Training material has not yet been created.

THE LATHE CAN CAUSE SERIOUS INJURY. ONLY APPROVED OPERATORS ARE PERMITTED TO USE IT.
</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 lathe but it must be emphasised that learning to take full advantage of all the capabilities of it 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

{{Note|This page is not maintained and is probably of only historical interest.}}

Below are a list of projects; some completed, some dead and some only twinkles in our eyes. Please add your project to the list (only good things come from sharing). If you have an idea for a project but are not sure how to get started then posting here or on the [https://groups.google.com/forum/#!forum/cammakespace Google group] is a great way to find helpful people.

== Communal projects ==

[[WorkbenchLinks|Workbenches]]- we need a horizontal surface to make things on, and people are keen to start making the makespace by building benches. See some suggestions for DIY workbench designs.

[[AutomatedStorageProposals|Automated storage/retrieval]]- a long-term crazy idea to build some sort of storage robot in the half-height storage area under the kitchen which will retrieve a member's storage box when they swipe their RFID tag. If you have a fleshed-out idea for how it ought to work, write up your proposal and link it from this page.

[[AncientMachines|Restoration / Fiddling with 'ancient' computers]] - a page to document the current status and work required on the old machines we have been gifted.

Eliminate the iron core and use just air. Use fine wire for the coils to keep eddy current losses down. Such machines would be ideal for many projects including Visventis and electric vehicles. Tools such as good laser cutters and CNC mills are important for making some of the parts. Let's talk.

| LED lights have numerous advantages except for cost. I am interested to make replacements for fluorescent tubes, but buying LEDs in the quantity to build 1 is not economical. If I design one it makes sense to share the learning and build 20. As soon as we have sufficient interest the LEDs can be ordered and construction can begin.

| Monitoring of home mains power usage by current clamp. The clamp circuit is wired to an Arduino which monitors the current and totals up energy usage. Data is sent to a remote server via an ethernet shield every five minutes ([http://pvoutput.org/intraday.jsp?id=3214&sid=2484 live data])
The system also monitors PV generation and temperature. Future plans include adding logging to an SD card for finer analysis, integration with home-automation system.

Markw: More accurate version of warning

{{RedTool}}

== WARNING ==

There have been problems with the CNC router when used at higher speeds than the manufacturer's recommended maximum of 3000mm/s. Steps can be missed and the height can get wrong, resulting in head crashes.

Users should not exceed the recommended speeds and should wear safety goggles. Using expensive or precious materials in the router is at the user's risk!

[[File:WP_20130509_005.jpg|thumb|460px|right|CNC Router]]

== 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

* [[Equipment/CNC_Router/Training|CNC Router Training]]

== 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.

== Instructions ==

[[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.

= 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.

== 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.

===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 guide rails (Don't oil them, it makes dust stick)
* 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.
23/12/15: complete maintenance checklist completed. controller cable slightly frayed at machine end, collet nut could do with being replaced. otherwise, everything fine.

== Maintenance Shopping List ==

* Cutters
* Sacrificial Bed (1.2m x 1.2m 12mm MDF)
* ER11 collet nut
* controller cable

= 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.

[[Equipment|Equipment]] / Laser Cutter

[[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:

== 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

== 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.

== 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.

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

'''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.

There are a number of honesty boxes for consumables in Makespace, including for the [[Things_and_stuff#The_kitchen_(Cakespace) | kitchen]], [[Equipment/Laser_Cutter_Stock | lasercutters]], [[Equipment/3D_Printer | 3D printer]], [[Equipment/CNC_Router | CNC router]], [[Equipment/Vinyl_Cutter | vinyl cutter]], metalwork area ([[Equipment/Lathe | lathe]] and [[Equipment/WarcoMill | mill]]), and [[Equipment/VacuumFormer | vacuum former]].

Rules regarding what must be paid for and how much will be made clear when you are inducted in the relevant equipment, and will probably also be displayed near the equipment or on its wiki page (see links above). If you are not sure, contact the owners or ask on the mailing list. Do not use consumables without paying.

Note that you must pay for wasted material, not just your finished product. This is particularly relevant for the 3D printer. It is annoying to set up a print which goes wrong through no fault of your own, but you still need to pay for the filament used.

In the case of the CNC router, although there is no communal stock, please remember that you still need to pay into the honesty box for using the communal cutters.

== Ownership ==

Money in the honesty boxes belongs to the Makespace community. It is up to the community and equipment owners to review whether the system is working and covering its costs, decide what to buy and when, etc. Consumables are not paid for by Makespace Ltd, but if there is a need for a new supply - e.g. a stock of consumables for a new piece of equipment - Makespace will usually 'seed' this with a one-off purchase or injection.

Owners and others who pay for stock are an essential part of helping Makespace to run and should not end up out of pocket as a result. To help the system run:

* always pay what you owe for your usage
* check with owners before purchasing stock
* if you nevertheless find you are out of pocket, contact the owners and the management to sort the problem out.

== Overflow float ==

Most of the honesty boxes have corresponding 'overflow' boxes in the office, and notes from the boxes in the main space are regularly emptied in order to avoid leaving significant amounts of money lying around.
