I have an SVG file made in Inkscape with a number of counters. Everything prints fine except for the design in the upper left (as well as all the copies of that art like the two on the upper right.)
The Cultist art prints very, very lightly or not at all.
I’ve tried comparing the object to the other objects in the file, but I can’t find what the difference is.
I had that happen to an svg with 3 words of text from Illustrator - outlined and merged as compound paths. One of the 3 words didn’t cut even though it showed up in the GUI as if it was going to, and was part of the same layer/color/etc. as the other two words!
I took a look at your file in design software and noticed that the designs that aren’t printing well have two layers that overlap. Your Glowforge won’t print overlapping vector designs. I’d suggest removing one of the layers and trying the print again.
