Thanks Marty,

I was aware that it can't be too healthy, I have an enclosure over my cutter and a vaccuum bed that sucks all the fumes outside. I leave the blower running with the lid closed for about ten minutes for the fumes to disipate before removing the parts. I did try cutting polycarbonate once and that did not go over so well, ther was a lot of yellow smoke so I shut the laser off and vacated! I cut mostly wood parts for myself and others when they need it, helps feed the jet fuel addiction!
