I decided to use my Glowforge to make components for a tabletop game I’m making. So I used it create the box, inserts for the box and some of the game pieces. I’m really pleased with how this has turned out so far.
The only challenge with it has been focusing on the EVA foam, for some reason the Glowforge reports that I can’t do that so the positioning is always off a bit, which means I have to leave a fairly large margin of error.
Sounds like a neat project. You could manually put the thickness in, so that the GF doesn’t need to focus. I’m assuming you’ve cleaned the camera… Maybe the lighting is off… What if you masked it with some tape? It might focus then.
The mask sticks to sticky stuff far easier than any other. I use masking tape, or a larger piece of masking if I have it and drag it across the parts needing weeding. if an edge curls just a bit It will weld onto the passing sticky and be easily pulled off
