I’m using a Bit Zero V1 and all of my cuts seemed to be off? I did some testing and it seems to be off consistently by -0.014"? I place the bit zero on top of the material (not on the corner) and probe Z using a 1/4" end mill. It touches and retracts so the Z position is 1.220". I then moved the bit down to zero and checked with paper. At 0.00" the paper moved freely. Had to move it to -0.014" before it put pressure on the paper. I duplicated this on the waste board without material and got the same results. Any suggestions?
Thanks,

Which Z-axis do you have?
Do you have a set of calipers? Could you measure your BitZero?

Hi Will, it’s a belt drive and the Bit zero measures 0.9865" full depth & 0.867" to the cut out.
Those dimensions are quite close and deviate from what’s expected by much less than the error you’re seeing
Have you calibrated for belt stretch?
Try setting
$102=39.9433141Thanks Will. It worked. I had to play around with the number, but I’m almost dead on at 0.001". I might have to get one of those $250 z-plus z axis someday?
Thanks for your help.
