If you're using this laser cutter for the first time, and you've been trained on the previous machine, please read the Upgrade Notes.
Training
You must not use the laser cutter without being trained. The laser cutter is unlikely to hurt you, but you can easily hurt it without training. For more information about laser cutter training, see the Lasercutter Training page.
Costs
- Training - £5 per person (payable to the trainer for that session)
- Usage - £6/hour
- Consumables - Bring your own and/or use what is in the off cuts bin, but always ensure (rather than assume) it's laser safe.
Safety information
- Never leave the laser cutter unattended while cutting: your material may ignite, and an unchecked fire in the laser cutter could be both dangerous and costly. We've also seen mirrors go out of alignment and cut into the cables, This is what a laser cutter fire does to a laser cutter:
- In case of fire: use the CO2 extinguisher by the laser cutter first. Do not use the powder extinguisher unless you feel that you can't control the fire. Put it in the logbook and tell the Mailing List: tiny flames while cutting are normal; anything more must be reported.
- Never cut PVC or chlorinated plastic: you should always know what material you are cutting, and chlorinated plastics should be avoided because they release chlorine gas when cut. Guidelines for how to test materials.
- You can't cut metal in the laser cutter: if you wish to mark the metal, please use Thermark / Cermark, or use anodised aluminium.
