I just finished cutting my first complicated project, and it failed pretty miserably after about 10 hours of cutting. I’ve attached some pics below. It’s a picture frame with lots of silly cutouts.
You can see it cut through a couple places in the middle (two small pieces fell out), but mostly just scored through to the bottom here and there.
The material is 6-mm Baltic birch ply, cut 7 passes at 100%, pass depth of 1 mm, starting at 18 mm (6 mm material, 2 mm glass, 10 mm cutting mat) at 100 mm/min with air assist. Each pass took about 1.5 hours, and I ran them two at a time over three days, cleaning the lens after every 2 passes, and lowering the start height to match the progressive pass depth (i.e., two passes at 18 mm, two at 16, two at 14, one at 13).
Any idea what I did wrong here or how to improve? Is this just the way it is with plywood, or am I getting the height or something else wrong?
Thanks for any advice you can offer!
