I’ve been using Chemcast acrylic using the relevant PG settings with success for several weeks (“thick PG acrylic” for this particular piece).
…this morning I just ran a file using a piece of acrylic I’d cut before, so I know that the PG settings were successful on this exact piece of material six times in the past.
The laser nearly set fire to the paper mask, didn’t cut all the way through, and moved MUCH more slowly than usual. Seems like significantly reduced power and travel speed combined for a terrible result.
Has anyone else noticed a sudden change in PG acrylic cut behavior?
