Dialing in the laser cutter settings for cutting out Hack-E-Bot chassis. I have to re-trace a few parts to get the settings right. The multiple passes produced flames in some spots.
The goal was to get the machine to cut the chassis as fast as possible with 1 pass. Unfortunately the cutter was not fine tuned and only cutting with about 50% power.
After some major work with aligning the mirrors and cleaning the lens, we got it up to almost full power in the end.
