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 … I’ve test with multimeter and i have +/- 130v. I dont use 1/16 or 1/50 voltage , im connected direct to the leads . Anyone can help me ? I use sheetcam with mach3 plasma post processor . Many peaple say that if I d’ont have floating head, i can use mach3 plasma post processor with my thc … hope you can help me !

I am afraid I can’t help with diagnosing your problem but the ‘Mach3 plasma’ post is the right one to use if you don’t have a touch-off switch.
Does the Proma THC show the correct voltage when the torch is on?
Yes he show the correct voltage , i’ve set the HU ( high voltage limit of thc) to 300v and that work … i don’t know why but its working… thank for reply ! I look to install floating head next week, so the apropriate post processor should be wish one ?
If Proma supply a post, use that one. If you aren’t using any special probing macros the ‘Mach3 THC with scriber’ post should work.
Ok thanks Les !!
