- Cut some 1.5mm neoprene fairly successfully - needs high power and it's a bit smelly. (Settings in the book.)
- Circle issue is fixed. It was a problem with the tension on the frontmost X drive belt.
- Did some awesome etching onto black anodised aluminium - 450mm/sec, 90% power.

Safety information
*** Please don't touch or fiddle with the laser cutter unless you've had permission from either Russ or Jonty. ***
- Please don't affect the cooling system without consultation - overheating or rapid cooling can damage the laser.
- Never leave the laser cutter unattended - Your material may ignite, and an unchecked fire in the laser cutter could be both dangerous and costly.
- In case of fire - Use only the CO2 extinguisher positioned by the cutter.
- 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.
- Do not try to cut metal in the laser cutter - If you wish to mark the metal, please use "Thermark Laser Engraving Spray / Paste", or use anodised aluminium.
