So i am trying to do a custom photo frame using the Glowforge to cut the openings for the photos. Not trying to do anything fancy with a bevel. When I cut without a mask, there is smudgy burn marks that I can’t get off even with denatured alcohol or acetone. I tried masking with blue painter tape and the tape ends up taking up the top layer of the mat board when I peel it off. I got a special “frog tape” low tack tape for delicate surfaces but this is doing the same thing, even when I try to make it even less sticky by sticking it to my tshirt first. Anyone got any ideas for how to either make a not-too-sticky mask, or settings that don’t leave char marks on cream colored mat board?
I did have success with engraving captions for the photos, which was the whole point of the project, so now I am being nit picky about not having the char marks. thanks!
