Machine is usable, but requires induction.

This machine requires induction or supervision to use.

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.

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 LightBurn Software Documentation

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 here.

  • 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.
Recommended Please wear goggles or a face shield

Material Notes Warning
Most woods Avoid oily and resinous woods Oily/resinous species might catch fire and dirty the laser optics
MDF You may experience a higher amount of charring
Plywood Get plywood that's laser safe Don’t use marine ply. Doesn't cut nice, burnt edges. High fire risk
Paper/cardboard Be careful, watch it closely. Fire risk
Cork Quality of the cut depends on the thickness and quality of the cork Engineered cork has a lot of glue in it, and may not cut as well.
Cloth/cotton/felt Only used natural fiber fabrics
Natural leather/suede/nubuck Can be cut if thin, or engraved at any thickness Do no use artificial leather, or chrome-tanned natural leather
Ceramic tiles, stone, marble, granite and similar Engraving only Must be covered in painter's tape first
Glass Engraving only Must be covered in painter's tape first. Be careful with the glass dust
Polyester (PES), Polyethylene (PE), Polyurethane (PUR) FOAM Check MSDS from supplier Do not use Polystyrene or PolyPropylene foam

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.
Any materials containing halogens (fluorine, chlorine, bromine, iodine and astatine), epoxy or phenolic resins Contains chlorine and other harmful chemicals that are released when cut Toxic fumes
PVC Contains chlorine Toxic fumes
Vinyl Contains chlorine Toxic fumes
Artificial leather, pleather, moleskine etc, as well as chrome-tanned natural leather Contains chlorine Toxic fumes
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
PTFE/Teflon Produces hydrofluoric acid Toxic fumes

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
