Mach3 Auto Tool Zero help

[piper1]

Hi Gerry thank you for the reply.
I have tried to enter the sensor thickness in the DRO (Z axis) on the front screen but it cancels out when i select the GOTO button.
I also tried entering it in the VB Script “Call SetDro (2,GageH) 'DRO(2)=Z DRO”
To be honest i don't have a lot of knowledge in the subject
