QtPlasmaC stops immediately after probing when Torch On Enable is active — no error, just motion halt
Description:
I’m using QtPlasmaC with a Mesa 7i92 and emulating both the arc voltage (via encoder.00) and ohmic probe (via HAL comp comparing encoder.00.velocity-rpm to a threshold).
Arc voltage scales correctly: ~285 V when torch is far from metal, drops to ~0 V on contact.
Ohmic probing (IHS) works fine — Z stops at contact and lifts to CUT_HEIGHT.
If "Torch On Enable" is OFF, the G-code runs to completion (no THC, as expected).
If "Torch On Enable" is ON, the program stops immediately after IHS and torch ignition — no error message, just motion halt and GUI power-off.
THC is enabled in material (THC = 1), and Auto Volts is ON, so THC should use the sampled voltage after probing.
Not sure who posted this but it wasn't likely the 'PCW' we know. Seems like something went wrong somewhere so whoever it was please feel free to reregister.
