===== Current Status =====

<WRAP safety half round>
=== Usable ===

Machine is usable, but requires supervision or induction by a supervisor.
</WRAP>


===== Usage =====

<WRAP round info half>
**This machine <wrap hi>requires induction</wrap>.**
</WRAP>
==== Induction ====

In order to get inducted on the laser cutter, you need to go to the following Eventbrite event and book a place for yourself on one of the available dates.

{{https://www.eventbrite.com/e/co2-lasers-induction-tickets-526927202447|CO2 Lasers induction}}

Inductions happen fortnightly.

=== Things to keep in mind ===

  * Inductions signups close 3 days before the event start. This allows volunteers to organise their life.
  * If no one has signed up for the date before it closes, the induction is cancelled.
  * If the induction is on (because people signed up in time), but the time has passed, you can always ask in discord if you can get into the induction.


=== Not Familiar with Lightburn? ===

You can find all sorts of information on [[https://docs.lightburnsoftware.com/index.html|LightBurn Software Documentation ]] 
 
You can watch all the tutorials [[https://lightburnsoftware.com/pages/tutorials| HERE]] 

=== Induction booklet ===

This is the documentation we use to give the inductions. It's always being updated and you can always find the latest version [[https://docs.google.com/document/d/1DxntbjFMqvW6n99LQBxf3kxHRsMhvC38AW4aCORk6-g/edit?usp=share_link|here]].
==== Recommended PPE ====

==== Guidelines ====

  * When operating this machine, **under absolutely NO circumstances must it be left unattended**.
  * If anything goes wrong, your first port of call is to always bang the big, red Emergency Stop button. It's there for a reason, don't be afraid of using it. Even the resident laser cutter experts have to hit it every so often, because things happen. 
  * Try to avoid staring at the cutting point. We know it's pretty & oh-so-mesmerising to watch, but it's very bright & you'll end up with temporary spots in your vision.
  * Only cut approved materials that are known to be safe. If you disobey this rule, you will create toxic fumes potent enough to put you in hospital and/or you'll generate gaseous forms of very strong acids which will literally eat away & dissolve the machine's insides.
  * The nearest fire extinguisher is by the door to this room. Don't use the fire extinguisher unless it's necessary, but if the situation calls for it don't hesitate for one second because a fire will spread //very// quickly inside the machine. Having to thoroughly clean & align a laser cutter is a pain but it's //far// better than having to replace a burnt-out shell of an ex laser cutter.

===== Workflow =====

  - Load machine material
  - Turn on the machine
  - Turn on the air compressor
  - Complete preflight checks
  - Set the focus
  - Export the job to the laser cutter
  - Ensure all machine doors are closed and the cutting area is clear.
</WRAP>
<WRAP third column>
==== Using Laser ====
  - Start the job at the control panel
  - Put money in the donation tin

<WRAP warning round>
===== What materials can’t be cut / engraved =====
Some materials when they are cut can catch fire really easily and some of them release harmful dust and gases that can damage the machine and even endanger yourself. As well some of them cut poorly leaving gooey residue behind. These are the reasons why the following material can’t be cut.

^ Material ^ Notes ^ Warning | 
|Metal |It simply doesn’t cut or engrave any metal of any thickness. | |

|Polycarbonate/Lexan/Makrolon  |Cuts poorly, melts and discolours, almost impossible to cut |Catches on fire | 
|Polystyrene, including Polystyrene foam |This is the #1 material that causes laser fires |Catches on fire | 
|Nylon |Melts and burns |Catches on fire | 
|ABS |Melts and burns |Produces cyanide gas with high fire risk. | 
|HDPE (Milk bottle plastic) |Melts |Catches on fire | 
|Epoxies such as those found in resins or glues, including epoxy-coated items | |Toxic fumes | 
|Fibreglass and carbon fibre |Thin carbon fiber mat can be cut, with some fraying - but not when coated. |Toxic fumes | 
|Cutting printed circuit boards (FR4 and other material types) | |Toxic fumes |

===== Maintenance =====
Caution – use of controls, adjustments, performance of procedures other than those specified here in may result in hazardous laser radiation exposure. Before starting cleaning or maintenance work always switch off the device at the interlock level.
Always keep the system clean, as flammable parts in the working area or exhaust area rise the fire hazard.

The cleaning interval strongly depends on the material that is being processed and the operating time of the device. Please bear in mind that only a clean machine guarantees optimal performance and reduces our service costs.

Cleaning the Laser Machine

^ Interval ^ Task ^
| Daily | Thoroughly remove all loose dirt particles and deposits in the interior of the machine |
| Daily | Clean out anything under the bed with the dustpan |
| Daily | Wipe down all the bars, the side & rear walls, the Aluminium rails, the underneath area. |
| Daily | Clean the viewing window with a cotton cloth. Do not use paper towels as they could scratch the acrylic  |
| Daily | Brush the air extraction grill if necessary  |
| Daily | Keep the Digifab room as free from dust as possible, vacuum it if it has not been done within the last fortnight  |
