tool height probe diving after back off

[thegreatwaldo]

Hi Balasz
I'm not sure what is happening with my tool height probe. When I press probe the z axis moves down touches the sensor pulls back a little bit comes down again , stops very shortly and then continues down about 27 mm and stops. Any idea what might be wrong ?

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 text 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.

Hi Balazs

Thanks for that I will check that out.

i had something like this when i re wrote my original probing code.
i fixed it by making all moves after the first downwards probe move incremental (g91) controlled then by + or - values to the movements
this ensured it could only go the correct direction
never a problem since

a nice touch was to add a "system beep" just after probing- so i knew it had hit the probe

I attached a small buzzer on the probe input. It's very useful!
