The other issue is that to cut nicely, you need an air assist to blow the debris out of the cut line.

This is a mod that I will add to mine at some point, cheap air pump and some means of directing the jet of air to the cut area of the laser beam. People are printing 3D versions and there are a couple of after market add on's.
Thanks Chris. I had not considered using multiple passes to make the cuts. Maybe I'll take the plunge since the price is pretty reasonable.
