Hi, i 've install my new thc from proma . I wired all wire and when i try "test mode " thats work perferctly , my z axis works up and down . When i try to cut some piece, the torch pierce and stay at this position . I have to e-stop .... and i saw that the thc doesn't reed any voltage from the plasma cutter. I've test with multimeter and i have +/- 130v. I dont use 1/16 or 1/50 voltage , im connect direct to the leads . Anyone can help me ?
-
I find why thc doesnt resd voltage, I reverse the 2 wires. Work peace clamp are the + and the torch are - . I still have the proplem when the torch pierce, the programe stop and stay at this point. On mach configuration , i enable thc on setting and input works on test mode ,so they are ok !? If I desactivate thc botton on mach screen, i can cut completely the part but thc not works

In Setup - motor tuning - mill options, is Allow THC movement even if not in THC mode checked? It should be unchecked.
