I have THC module plugged in to correct ports but machine is not controlling z axis during cutting and is not recognized on machine tab but i can manually control it and cut a program if i manually lower z with the software.
May be unrelated but sometimes torch stays on when moving from one cut to another.
Torch Height - Post the first 30 lines of your G-code from one of your cut files so the more advanced can have a looksee. My money is on IHS and or THC is turned off in the post processor.
Torch stays on - What plasma cutter are you using? If you have a 2T / 4T option, make sure it is on 2T.
