the other problem i had was that my ohmic probe was by default trigged.
after i invert the pin for ohmic probe, it works.
thanks you so far.

My OHmic Probe circuit is connected to parport.0.pin-16-out.
As i wrote in one earlier post, the circuit is still activated when i start plasmac.
When i turn it off in the RUN Panel then my circuit is stays on.
I have measured PIN16 and GND and get no stabel voltage and there is no differents
when i turn probe on or off.
But, when i measured pin16 and pcgnd on the BOB then i get 5V. And this turns on and off when i trigger the checkbox in the RUN panel. My circuit GND is connected to the powersupply.
Any one can help?

parport.0.pin-16-out should be connected to plasmac.ohmic-enable, this is then used to enable your ohmic circuit.So next step

plasmac.ohmic-probe needs to be connected to the parport.0-nn-in that your probe is connected to.
pin16 should change state while probing.

If you look at my diagram. I connect physically PIN16OUT to my circuit and probe with IN PIN. Probe works fine.
You write that "Pin16 out" change when i probe?
I thought that i can enable or desable it by hand over the run panal. But this doesn't work.

The Ohmic Probe Enable only enables plasmac to do ohmic pribing, it does not change the output. The output only comes on while plasmac is probing.

I'm confused.
which way would you suggest to check the machine for correctness?
Is there a test routine to ensure correct functionality for the whole machine?

Sorry, it may be the way I am explaining it.hhmmm
I'm confused.
Unfortunately not, it is a matter of testing one thing at a time.which way would you suggest to check the machine for correctness?
Is there a test routine to ensure correct functionality for the whole machine?
EDIT: can you post your complete config.
