probing isnt working

[danielchindea]

Hello,

I am new to uccnc. Just bought the axbb-e.
Everything runs smoothly except probing. I cannot make probing to work as expected, either using the default macro button or probing plugin.
If I home the machine and probe using a simple touch probe, it works. If I hit probing again it works. If I move the Z axis then it's not working as it should. It comes down by a random amount and turns back+ retract. I cannot use it at all like this.

What should I do? Actual probe (hardware) is working ok. I've checked it using the debug plugin and it triggers when it should. It drives me completely nuts as I have work to do.

Thank you,

Daniel

Either of the two MDI commands works erratically, moving down from 2 to 20mm with apparently no logic.
No false probing is happening as I monitor the pin.

Any ideas?

Got it to work. No fault on UCCNC.
I reversed the wires going to my touch probe (clamp and plate). Although I cannot meter any voltage or continuity between any of them and the spindle house. Do you have any explanation for this?

Thank you,

Daniel
