I installed ohmic3 comp.
Put the Hal file into the config folder of my machine and edited the ini file and added the ohmic Hal file.
Linuxcnc starts now without any error messages.
Probe test works.
But if I press ohmic test nothing happens.

Between 2 and 25 volts.
If I touch the torch with the negative cable from the power supply that is supposed to go to the workpiece I get a stable voltage of about 25 volts. If I put the same cable into the water I also get stable 25 volts.

it was some dirt that accumulated between the torch nozzle and the Shield.
after cleaning the voltage dropped drastically. Between 2 and 10 volts.
after this I put a pull up Resistor between positive in and negative in of the Thad.
that put the fluctuation to below 5 volts
Now it looks like ohmic probing works perfectly.

In halshow I can see that the machine reads them. But that’s all if I press the white button that is configured to start a cycle nothing happens. Are there more things that I need to configure so that the button will work?
Is there any tutorial about adding physical buttons?

Could I move the appropriate lines for these buttons from my Hal file to the postguy halfile. And just replace the pins that pncconfig created with the appropriate Qtplasmac external Hal pins?

PNCconf has not been taught anything about the external HAL pins.So basically pncconfig does not do configurations that are specific to qtplasmac.
Yes, that should work fine.Could I move the appropriate lines for these buttons from my Hal file to the postguy halfile. And just replace the pins that pncconfig created with the appropriate Qtplasmac external Hal pins?
