@TomWS Lead-in, cut starting point, and cut direction are set/managed by LB feature and editing.
Torch Probing, Pierce Height, Pierce Delay, Initial Torch Height, are set in the custom VIM macro.
And because of the THC design/model that I have, I also use a preRetract Delay after the cut; the reason for this delay is to allow time for the THC to switch Z control back to the CNC controller.
I edit the custom VIM macro file for adjusting to different material types and thicknesses. Crude but effective Most of my cutting involves artsy crafty projects using 18ga - 10ga mild steel, and I’ve found the PH, ITH, and PD to be good enough at a common setting for all. Soon I’ll be cutting some 0.250 mild steel, and I suspect some of that may change a bit.
Notable point: The Proma SD THC has a settable Delay parameter, which I find works best at 3.0 seconds. This means the THC won’t switch the Z control wires to internal for that delay period, which is why the PH to ITH transition works, but this delay also keeps Z from moving in short cuts where the plasma arc voltage can fluctuate somewhat and where the cut material is not likely to have warped yet from the heat.
I suppose one could plasma cut without a THC or the per-cut torch touchoff routine, in which case LB’s Cut-Through feature would suffice as the pierce delay, but there would be no Z moves for transition from PH to ITH.
