I have had my Glowforge for several years now, and cut wood and acrylic mostly. Up until the last couple of months I have NEVER had a problem with the masking paper catching on fire, but now it is happening literally any time I cut wood or acrylic (engraving is ok)–even on the materials I have had for a long time and were previously not problematic.
My lens is clean, the crumb tray is clean, the mirrors are clean. This was never a problem, and now is ALWAYS a problem. Did something change with the software? Anyone else having similar problems?
I have a Plus (circa Spring 2019), converted to an additional air assist and a 6" duct in early 2020. The fires did not start until September of this year, and very suddenly. I’m stumped.
