I have had the Auto Zero probe for a couple of years and it has generally functions as expected. XY zero was always set at the center of the bit (both with auto and entering bit diameter). With the latest version of Gsender my XY is set with the edges of the bit lining up with the edge of the material.
I supposed I can jog in either direction 1/2 the diameter of the bit and reset zero but not sure why the change in results.
I have an Xcarve running GRBL 1.1h

I have tried with $13=0 with the same results and the same whether probing XYZ or XY only.
