Here is mine settings. Does works for me. Touch off (+ Pierce delay / high ..) only. No THC

Not good logic in previous file.. Z2 may be better.

I am no expert but try to achieve the same (touch off - no THC) I have learned that; It is important to check that the M03 starts the plasma cutting routine and runs it as expected. Insert the M03 command into MDI and run it. For my part I have set target volt the same as analog volt input register value. And has put an input pin so THC ON is always on. Although manual mode is what is used. (the plasma help document in the Mach4 folder is mandatory reading) If it works that way, then the post processor in Sheetcam should be as minimalist as possible (since Mach4 takes care of pierce height, etc.) In fact, newer Sheetcam have post processor named for Mach4 (probably Mach3 plasma_noZ could almost be used) But as I see it, Mach4_PlasmaPost has a weakness in that they do not lift the torch between cutting (rapid move?). I have therefore tried to edit it in a way that, in theory, I think it can work. Haven't tested it yet.
