I have recently bought a 40W laser and have now got it installed and working! I have tried various different materials for cutting and engraving, and have had various degrees of success. I thought I would open a new thread for non-technical Q&A about cutting and etching.
I have various questions, and may be able to offer some help with other peoples problems.
When all my kit arrived the air-assist pump was wired for 110V and as I live in the UK it needs to be 240V:violin:. While waiting for a transformer to be delivered I decided to experiment with various materials. Engraving was fine, but I cannot cut through 4mm plywood without it charring badly. Is this because the compressor is not attached, or could it be something else?
