I am using a Hyperterm 105
I also should say if I use the float switch as probe, it goes down hit the switch, goes up and starts cutting as per the program. So inputs are ok. getting arc and cutting drawings with no THC or ohmic.

You have not connected "ohmicsense.ohmic-on" to anything.
Adding this to your ohmic3_cfg.hal file should do the trick:
I had to debounce the output from the ohmic3 comp file to get it to work reliably, so this does that for you. I'm sure someone will chime in that it's not necessary, but I found it to be. 5mS works fine, it will add a little "pressure" to the sense. That said, I can detect aluminum foil without deforming it.
If you don't want it debounced, change db_ohmic.delay to 0 in the tn1_connections.hal file. I recommend HalScoping the output and figuring out what's necessary for your setup.
For the THC, your tn1_config.cfg file shows that you've not set the arc-voltage-offset. So I imagine your Arc Voltage is not displaying correctly, if at all. The PlasmaC manual tells you how to set that. Further, you can verify it by hooking up a known DC power source (say a 9 volt) to it and verifying it actually reads 9 volts.

Thank you. This is what I was looking for. I had offset in the config but it showed -30 volts in the gui so I removed it. and it shows 0.
I'll stick 9vdc on it and see if it shows up on screen

OK so I set that line in the ohmic3_cfg.hal file and still does nothing. Pressing the Ohmic test should start the torch going down?

No, ohmic test turns on the ohmic circuit, so you can test for a shorted tip (by looking at the ohmic LED) which sometimes happens from dross, or water from a water table.
You want to click Probe Test. If ohmic is working you’ll see the ohmic LED light up.
As for the THC, use the calculator link in the docs. Sounds like you don’t have something quite right. With the correct numbers it should be ~0v

I am just trying to get ohmic working now. After I will tackle thc.
Roger on the ohmic test button.
I don't see where my signal in from thcad is the hm2_7i92.0.encoder.00.velocity. I cant find that int he config and this is where the ohmic signal first hits linuxcnc.
I tried this: net plasmac:ohmic-probe hm2_7i92.0.encoder.01.velocity => db_ohmic.in in connections.hal and it didnt like it cause it needed a different input type.
But there is nothing with encoder.01.velocity, so I would thinkl that is where an issue lies.

It is in my Ohmic3_config.hal
net ohmic-vel ohmicsense.velocity-in <= hm2_7i92.0.encoder.01.velocity
So that's not the issue.

I thought I saw it in your ohmic3 Hal file?
And no, dbounce wouldn’t like velocity, it requires a bit input (on or off). Velocity is a float.
Have you tried clicking probe test yet?

Yes, it goes down and hits the float switch and the ohmic probe led dont turn on in the gui, counts down from 24 then moves up.
I found the encoder connection. It is in my files.
