When I’m cutting with a 1/2 inch MDF board directly on the waste board the z-axis starts out at the correct depth then starts cutting above the workpiece about 2 inches away. This issue does not exist when I stack two 1/2” MDF boards though. I ran the test calibration pattern to almost perfect depth across the whole cut when the board is raised that extra 1/2”.
Any help would be greatly appreciated. Thank you!
