Hey Guys, I may have already figured out the issue, but I wanted to ask for other’s thoughts and advice and maybe to confirm our theories.
We’ve been having a lot of trouble lately cutting through our 1/8" baltic birch. It seemed to work for awhile, but maybe we got lucky with better pieces early on.
I’ve got the cut settings set to 155/full and set the height using digital calipers. We’d find a lot of stuff wouldn’t fully cutout, so we’d run another pass again, and still no progress, what the hell?
We are getting tired of using exacto knives to try and slice things up to finish the job. On our latest design we noticed a distinct lack of scorching mark around the edge of the circle (on the front of the board, not pictured), like it wasn’t even cutting, although it did at least score somewhat. We also investigated a triangle after having to exacto it out and noticed the fill in the middle layer was missing right where it kept failing to cut!
We assume it must do a cut through the first of the 3 layers, then fail if the center is missing and then even on a second pass it can’t focus or is tricked or something so it doesn’t cut through the final bits.
Are we just unlucky with bad wood and we stumbled onto the real issue, or is there something else we should be doing as well? It doesn’t seem like slower cuts make any difference.
You can see on the back of the design where it failed to cut.
