setting tool probe

[thegreatwaldo]

I have a 42 mm high tool sensor. When I press the probe button the cutter comes down touches the switch pulls up comes down stops and then keeps going for about 27 mm. What am I doing wrong. Is there a setting to input the touch sensor height ? Help

Cheers

The probe button calls the M31 macro. The macro is coded in the M31 macro file in the UCCNC/Profiles/Macro_Yourprofilename/M31.txt.
Open the probing macro with a screen editor and you can then edit the macro freely.
Everything about the probing button action is coded in that macro like if it makes a single or dual probing movement, the probing feedrates, the retract distance etc.
