Though, I just ran this on some painter’s tape I put on the crumbtray. The head hit the front door down in the right corner.
Caused the head to pivot off the magnet mount a bit, and redirected the laser forward. It was traveling from back to front at that point. When it traveled to the left, it snapped back into place.
At least now I have a nice visual indicator on the crumbtray to tell me where the cuttable area is.
Too bad it doesn’t match up to the GUI:
