It is worth noting that these instructions were written with the [[Silvertail A0 Laser cutter]] and [[Greyfin A2 Laser Cutter]] in mind, these are now defunct and are different to our current laser, [[Boxford_BGL1390_Laser_Cutter|Boxford BGL1390 Lase Cutter]]. Whereas common things such as cost, induction requests, and bookings will remain the same, specifics around setup, operation, software, and troubleshooting may vary, this will be updated soon now that the Boxford BGL1390 is fully installed and opertational.

*'''Don't ever exceed the 85% power setting. We put this rule in place to extend the life of the laser tube which is expensive to replace.'''
 
*'''When the laser is in operation it is very important you keep an eye on it and you do not leave the laser area. Whilst it is very rare for materials to catch fire whilst cutting or engraving, this can happen and has occurred at times.'''


The Hackspace held a successful pledge drive and purchased an A0 laser cutter from Just Add Sharks early 2014, which was installed later that year in May. The project information related to that is [[New_Laser_Cutter_Project_2014|available on the wiki]] if you are interested in the decision making and pledge drive.
*'''Be familiar with the location of the CO2 / powder fire extinguisher in the laser area.'''


=== Inductions and Training ===
=== Inductions and Training ===


You need to have had [[/Inductions|an induction]] on the laser cutter to use it; this costs £20. Only inducted Nottinghack members are authorised to use the machine; it is not available for use by the public. Once inducted you will have 24/7 access to the laser and be able to use the online booking system through HMS.

You need your [[Nhtools|RFID access card]] to use the machine. RFID cards will only work if they have been activated during a laser induction. Please do not let other people borrow your card; you will be held responsible if anything goes wrong - and of course the usage charges would be applied to your account balance!

Please do not let other people borrow your card; you will be held responsible if anything goes wrong - and of course the usage charges would be applied to your account balance!


A booking system for people who have had an induction is available on [[HMS]] which also allows you to track laser time against your Nottinghack budget - it can go up to £20 in debt and you are emailed with instructions on how to pay it off. No money can be taken at the machine itself.
A booking system for people who have had an induction is available on [[HMS]] which also allows you to track laser time against your Nottinghack snackspace account. You will only be able to turn the laser on with a positive snackspace balance. If funds available in your account drop below £0 during usage, it will continue to function but you will not be able to turn it on again once you remove your RFID card. No money can be taken at the machine itself, you will need to top up by payment card on [[HMS]] or use the payment machines in upstairs [[Members Storage]].


=== Costs ===
=== Costs ===
 
The A0 laser cutter costs £3 per hour; it will be charged to the nearest penny. Your normal HMS account will be used to track and pay for this. Credit should be added in advance to your Snackspace account via the HMS web page. Note, that the laser won't turn off when you reach £0 (this allows a laser cut to complete), but you won't be able to put your card on the laser to turn it on again.
The A0 laser cutter costs £3 per hour; it will be charged per penny. Your normal HMS account can be used to track and pay for this up to the limit of £20, or credit added in advance using methods in the space. Note that the laser won't turn off when you reach your limit but you won't be able to put your card on the laser to turn it on again.


Anyone who pledged will have been given their pledge amount in laser credit (separate from the costs for vending machine items or other things).

The charge is to encourage users to prepare their files in advance to keep the unit as free as possible. Money paid will contribute towards the provision of laser-related supplies such as replacement laser tubes and lenses. A booking system is available to book slots on the laser for up to 2 hours at a time, see above.

If the laser isn't cutting cleanly (and your settings are correct), check the focus with the guide. It should be at or slightly (e.g. 1mm) inside your material. If you're cutting 6mm or thicker, you may need a second pass. In this case it may be worth raising the bed, but usually not.

Occasionally the laser will report an error on the control panel screen, this will give an indication of the problem e.g. Y slop over" which means that the project will be outside of the bed in the Y Axis.
 
If this does not help, the try to power off the laser and power it on again.
 
If the suggestion above does not work, try repeating the process with a different file (e.g. different size, date made, program made in etc.)


Occasionally someone will report a "Soft Stop". At present there is no definition for this, but is usually considered to be the laser attempting to cut unsuccessfully before the head resets to datum.  
If you believe the laser cutter is broken, or there is an issue, please email laser@nottinghack.org.uk!


First, check the file you are trying to cut is within the laser-bed simulation in LaserCut. You can zoom out using the wheel on the mouse or by holding Ctrl and pressing + or -. If the drawing is not within the boundary, move it to within the boundary. If it doesn't fit, you can't cut it as it is too large. You need to break it down into smaller parts.
=== Software ===


If this does not help, the following is a suggestion of what might be done to alleviate a problem:
==== Lightburn ====


# Close LaserCut5.3
Lightburn is our primary laser cutter software. See the [https://docs.lightburnsoftware.com/index.html documentation] for more information on how to use it. A PDF manual is also available for offline viewing.
# Switch the laser cutter off (removing your RFID card and allowing the machine to shut down is fine)
# Reset LaserCut5.3 to factory settings
# If possible, re-save your file in whichever program it was created in
# Open LaserCut5.3 and reimport file
# Switch the laser cutter back on
# Open the Download window in Lasercut5.3 and clear any files (Delete all). Next, "Download Config file". If successful, the laser will emit a second-long "beeeep". Otherwise, close and reopen the download window and try again.
# Upload your file to the Laser cutter and try again


If the suggestion above does not work, try repeating the process with a different file (e.g. different size, date made, program made in etc.)
'''To get a discounted licence email laser@nottinghack.org.uk'''


If you believe the laser cutter is broken, or there is an issue, please email maintainers@nottinghack.org.uk with the word [laser] in the subject line!
It is installed on the laser PC and on the PC in the [[Blue Room]].

This page contains information about operating the space's Laser Cutter. It is located in the Laser Area and requires an induction to operate. It also needs you to book a time slot in HMS prior to use. The laser is the Boxford BGL1390 Laser Cutter.

Laser Cutter Guidance

Note Important note:

It is worth noting that these instructions were written with the Silvertail A0 Laser cutter and Greyfin A2 Laser Cutter in mind, these are now defunct and are different to our current laser, Boxford BGL1390 Lase Cutter. Whereas common things such as cost, induction requests, and bookings will remain the same, specifics around setup, operation, software, and troubleshooting may vary, this will be updated soon now that the Boxford BGL1390 is fully installed and opertational.

Note Important note:

  • Don't ever exceed the 85% power setting. We put this rule in place to extend the life of the laser tube which is expensive to replace.
  • When the laser is in operation it is very important you keep an eye on it and you do not leave the laser area. Whilst it is very rare for materials to catch fire whilst cutting or engraving, this can happen and has occurred at times.
  • Be familiar with the location of the CO2 / powder fire extinguisher in the laser area.

Inductions and Training

You need to have had an induction on the laser cutter to use it; this costs £20. Only inducted Nottinghack members are authorised to use the machine; it is not available for use by the public. Once inducted you will have 24/7 access to the laser and be able to use the online booking system through HMS.

If you have not been inducted, please do not attempt to use the laser yourself or borrow someone's card. If you are inducted, You may offer to run the laser for someone else, but you will be responsible for anything that may go wrong.

Usage

RFID cards go here to activate machine.

You need your RFID access card to use the machine. RFID cards will only work if they have been activated during a laser induction. Please do not let other people borrow your card; you will be held responsible if anything goes wrong - and of course the usage charges would be applied to your account balance!

A booking system for people who have had an induction is available on HMS which also allows you to track laser time against your Nottinghack snackspace account. You will only be able to turn the laser on with a positive snackspace balance. If funds available in your account drop below £0 during usage, it will continue to function but you will not be able to turn it on again once you remove your RFID card. No money can be taken at the machine itself, you will need to top up by payment card on HMS or use the payment machines in upstairs Members Storage.

Costs

The A0 laser cutter costs £3 per hour; it will be charged to the nearest penny. Your normal HMS account will be used to track and pay for this. Credit should be added in advance to your Snackspace account via the HMS web page. Note, that the laser won't turn off when you reach £0 (this allows a laser cut to complete), but you won't be able to put your card on the laser to turn it on again.

Anyone who pledged will have been given their pledge amount in laser credit (separate from the costs for vending machine items or other things).

The charge is to encourage users to prepare their files in advance to keep the unit as free as possible. Money paid will contribute towards the provision of laser-related supplies such as replacement laser tubes and lenses. Prior to use you will need to book usage slots on the laser (max 2 hours at a time) see above.

For guidelines these are the costs over an hour, since larger jobs can take a long time especially if engraving.

Time Cost
10 Minutes £0.50
20 Minutes £1.00
30 Minutes £1.50
40 Minutes £2.00
50 Minutes £2.50
1 hour £3.00

Problems

Remember, it's always worth trying a test-cut before attempting to cut something - a small circle or square can be drawn in Lightburn if necessary.

If the laser isn't cutting cleanly (and your settings are correct), check the focus with the guide. It should be at or slightly (e.g. 1mm) inside your material. If you're cutting 6mm or thicker, you may need a second pass. In this case it may be worth raising the bed, but usually not.

Should anything go drastically wrong, the first people to speak to should be one of the laser inductors or someone on the Laser Team. They can be contacted in person or via email (laser[at]nottinghack[dot]org[dot]uk) or on Discord.

Occasionally the laser will report an error on the control panel screen, this will give an indication of the problem e.g. Y slop over" which means that the project will be outside of the bed in the Y Axis.

If this does not help, the try to power off the laser and power it on again.

If the suggestion above does not work, try repeating the process with a different file (e.g. different size, date made, program made in etc.)

If you believe the laser cutter is broken, or there is an issue, please email laser@nottinghack.org.uk!

Software

Lightburn

Lightburn is our primary laser cutter software. See the documentation for more information on how to use it. A PDF manual is also available for offline viewing.

To get a discounted licence email laser@nottinghack.org.uk

It is installed on the laser PC and on the PC in the Blue Room.

If you would like a copy of the latest Lightburn Materials Library it vccan be downloaded here - File:Hackspace Library.zip

Inkscape

Inkscape is one of the most useful SVG tools and available for free on any platform (the Mac version however is hard to install). The help here on the wiki shows the best export settings and the different tools that help create a perfect laser cut file to import!

Adobe Illustrator

Illustrator by Adobe is a high-end paid-for vector graphics software tool. The Laser Cut program will import Adobe Illustrator files (given certain save options - no compression!). The main issue is that the Laser Cut program doesn't seem to export colour, but DXF export is still available - use R14 settings, but we had some issues testing this.

If anyone is able to add some notes (as to settings, such as using mm sizes!) and screenshots of save settings in the future that would be welcomed.

Notes: When designing in Illustrator work in millimetres as your unit. On export as DXF, select AUTOCAD Version: R14/LT98/LT97. The artwork scale will show 1mm = 1Unit(s). Change the unit from millimetres to points. The scale should now read 2.8346 points = 1 Unit(s). See the screenshots below.

Draftsight

Draftsight is a free suite of software that can plan out diagrams, and save to DXF format. More information to come. It runs on Windows, Mac and Linux. Update (2019): DraftSight is no longer free, and the 2019 edition installer attempts to prevent you from running one of the earlier free versions on your computer ever again. They have also announced that all free versions of DraftSight (2018 and previous) will cease to work on 2019-12-31. Be cautious.

Laser Cutter materials

Types of materials

You can have a look at what materials work well on the laser at what settings, and where to buy materials.

Main laser materials are wood, certain plastics and paper. Other materials may work, depending on what they are made of. Please note however that the laser cutter will not cut metal. You can see a reasonably complete list of what is laser safe here and here and a list is also kept on the whiteboard next to the desktop PC.

Materials available at the space

There may be some scrap material available to cut on the racks by the machine.

Acrylic of different colours and sizes can be purchased from the solids vending machine in slots F1 (30p), F2 (£1.20) and F3 (£2.70). F1 is for 10x10 cm pieces, F2 is for 20x20 cm and F3 for 30x30 cm. Once purchased you can collect your sheet from the shelving near the laser.

Rotary Tool

The laser cutter has a rotary tool that allows cutting and etching of cylinders/cones/radially symmetric things. It is stored under the laser PC table.

It has a separate wiki page.

History

The original red A4 laser cutter has now been removed and is no longer available for use.

The Hackspace held a successful pledge drive and purchased an A0 laser cutter from Just Add Sharks early 2014, which was installed later that year in May. The project information related to that is available on the wiki if you are interested in the decision making and pledge drive.

In 2023 the Hackspace held a successful pledge drive for a newer Boxford A0 laserr cutter. It was installed in early 2024.
