I'm having trouble engraving and cutting clear acrylic sheet. I'm getting some blow-off residue on the surface that looks a lot like smoke residue after engraving wood, except it is a frosted clear color. This is on 1/8 sheet acrylic, and it remains next to both engraved and cut lines.
After experimenting to find the right settings, this is what I am using: engraving 100/40 and cutting 15/85/5000. This is with the exhaust fans running and with air assist running. I got similar results after trying again with the air assist off.
I haven't had this issue before with acrylic. Does anyone have any ideas or suggestions?
Thanks,
Ric
