So, I’ve been through this before, and never got it resolved. (View inside appears to resize) I stepped away from cutting boards for a while because it was making me crazy. I’ve done other non-PG materials like Ikea Cork Trivets, non PG acrylic and slate coasters with no problem. So here I am, today, feeling confident that I can make my cutting boards work, after doing a couple more cork trivets with auto focus, no problem. I had done them with no crumb tray but propped up to just about exactly where PG medium materials would be. Then I did auto focus. I did two types of cutting boards, and the result was exactly the same (even though the boards were slightly different thicknesses). They shifted up about 1/2 inch. I didn’t take a picture of the first one, which was a small Ikea bamboo cutting board, but here’s a small beechwood paddle board.
I’ve cleaned my machine, I’ve calibrated it, and what ever other standard trouble shooting steps there are. Why does my machine hate cutting boards???
