I presume because there is a diamond at the end of the bit, that explains why I cannot use my XYZ probe, because the diamond in not conducive, therefore cannot complete the circuit. Does this have to be done manually? or is there another option?
Use a different bit to do the xy 0 then the diamond bit just lower it till it just touches a piece of paper or even the material itself. When you get close use the screen control .1 to lower it slowly to the point of touching. Then you are good to go.
Many thanks… You are a star.
