So im some what having the same issue but im not as experience as you fellas.
Can you guys help a bro out maybe?
I built a plasma table with touch off head as well...all pins are correct in the software, using mach 4, sheetcam and i have an ess smooth stepper. Aaaaaaallllll i want to do is just include the touch off sequence at every cut start........and im loosing my mind here! Should there be a specially made post processor (sheetcam) for this to work? Do i have to download something from warp9 (ess) to work properly with mach 4? Or is there something im not doing correctyl in mach 4?
Any way you guys can explain this process thouroughly? 😭
