But even so... If your probe ends up in slightly different positions... If you don't have the probe going up and down for each point it should produce pretty consistent results. Going up and down for each point would not be ideal. Do you have the probe retracting and re-engaging for each point? If so, I think you want to put a stop to that!
Hi Roxy,

The probe only goes up and down once. After it finishes the G28 it retracts, and then extends right before G29. This is unnecessary, how do I stop this from happening?

I think you are right, even if it overshoots a little bit, it shouldnt account for a change 3 or 4mm in offset. It is so strange.
