Is the correct depth set in the file? Check zeroing bottom/zeroing top.
Possible Causes:
The value of the thickness of the Z zero plate is not set correctly in the zeroing routine, which causes the Z to not zero to the correct location. “TS” to fix, follow prompts.
Run z-zero routine, sent the Z axis to zero and verify that the bit reaches the top of the material. Then, mark the shank of the bit where it meets the bottom of the collet, now run a test cut below 0 and see if the bit moves up in collet during the cut. If it does, the bit has slipped, replace the collet and collet nut and ensure proper installation.
