I must be missing something. plasmac.arc-voltage-in voltage-out, as well as hm2_7i96.0.encoder.00.velocity don't show anything, all zero.
Is there another component I need to load?
The thcad is blinking, and blinks faster when I put voltage on the input. I tried F/1 and F/32. Also, the bipolar/unipoler jumper is confusing referencing the silkscreen vs the manual.

Yes, the THCAD wires into encoder AAll I know is i'm to wire into encoder A
- run LinuxCNC
- open halshow and watch plasmac.arc-voltage-in and plasmac.arc-voltage-out
- set Voltage Scale in the Plasma Config tab to 1
- set Voltage Offset in the Plasma Config tab to the value read from plasmac.arc-voltage-in
- apply a known voltage to the TCHCAD input
- set Voltage Scale in the Plasma Config tab to (known-voltage / plasmac.arc-voltage-out)
you could probably keep tweaking to fine tune further.
Basically:
Voltage Offset sets the displayed voltage to 0 when there are zero volts present.
Voltage Scale set the voltage to the correct value for a known voltage.
Cheers, Phill.

if hm2_7i96.0.encoder.00.velocity shows zero then you must be missing a connection, you need 0V, +5V, FO- to ENCA- and FO+ to ENCA+ (that is to my 7i76E at least)I must be missing something. plasmac.arc-voltage-in voltage-out, as well as hm2_7i96.0.encoder.00.velocity don't show anything, all zero.
You shouldn't need anything else.Is there another component I need to load?
I have mine at F/32 (recommended by PCW)The thcad is blinking, and blinks faster when I put voltage on the input. I tried F/1 and F/32.
Yes, I see what you mean, mine is set as on the silkscreen, W1 is up for UnipolarAlso, the bipolar/unipoler jumper is confusing referencing the silkscreen vs the manual.

I did get my torch start problem figured out. I had the arc voltage set to to high so sometimes it would not hit that voltage and would error out.

I disagree with Phill here. you don't need to put a voltage on the input as you have the calibration data from mesa so you know what it will be reading at 10 volts.
Make sure the board is set to 1/32 divide mode on the link on the THCAD. Divide both values on the board by 32 and write them down. Work out what will be the actual volts indicated. Say you have a 30:1 divider and full scale frequency is 28000. 10 volts x 30 = 300 volts. So your scale is 300/28,000 = 0.0107 and your offset will be 1/32 of the 0 volt frequency you wrote down earlier (probably around 3800)
The 1/32 setting is better for LInuxCNC's servo thread speed and allows more accurate sampling by the THCAD via some kind of averaging algorithim in the chip.

Speaking of barebone config, the last hal component I need to hook up is the torch voltage. I'm running a 7i96 and a thcad10. What lines do I need to get the thc hooked up? Right now the only hal config I have in regard to this isBut it's just a placeholder to get the config to load until I figure out what it's supposed to be. All I know is i'm to wire into encoder A and somehow calibrate with the sticker on the back of the thcad card. I know the THCAD manual has a simple formula for converting the frequency to voltage with these calibration figures, but when I was looking through plasmac.comp I didn't see where I use these.net plasmac:arc-voltage-in hm2_7i96.0.encoder.00.velocity => plasmac.arc-voltage-in

Here is my THCAD connection pinouts. Ignore the numbers in brackets. Theu are specific to my machineI must be missing something. plasmac.arc-voltage-in voltage-out, as well as hm2_7i96.0.encoder.00.velocity don't show anything, all zero.

Thank you rod, I actually found your pinout chart a little while ago. That's when I decided I better use the frequency divider.
Anyway, I figure troubleshooting my THCAD may be getting off topic here. I've posted some more info over here: forum.linuxcnc.org/27-driver-boards/3659...6-and-thcad?start=30

Thanks John,
I managed to find LMDE2 and made a new virtual machine last night, loaded all the dependencies, cloned plasmac and built LinuxCNC.
The colors work fine, I really don't know where to go from here...
Did you guys try the mod to the glade file?
Cheers, Phill.

You guys think a THCAD calibration setting calculator like this would be a useful addition to something like the configurator?
jscalc.io/calc/NTr5QDX6WgMThBVb
[edit]
I hope it works right because I can't figure out how to get back in to edit the stupid thing.. anyway I figure
scale = thcad_model_voltage * frequency_divider * plasma_divider_ratio / (max_voltage_frequency - zero_voltage_frequency)
offset = zero_voltage_frequency / frequency_divider
where max_voltage_frequency and zero_voltage_frequency are from the calibration sticker x1000
