    THC G-code problem

    Hi everyone, I have a problem with THC G-code. When I uploaded the G-code in Planet TNG software and started to run it, the program just only ran a little bit and stopped at N51 line. I don't know why. Below is my G-code for referent. Could somebody help? Thanks a lot.

    Hi PlanetCNC,
    I have already connected the THC (Proma SD) with plasma source (Hypertherm 45XP) dirrecty as your guide on the blog but the machine just only ran over the THC code line a little bit as the picture. First, the torch contacted with the tube face then the plasma arc fired and stopped even when I have already tested THC operation well before. It did'nt work like as your clip ( The torch and the steel surface contact together then the torch move up and fire the plasma arc).Have I missed something in the way to set up on the software or wiring ? Could you please to show me?.

    Do you have a OK arc pin configured in settings? If yes then software waits for un-existing ARC OK signal.

    Do you use 10.30 version of TNG?

    Thanks for your replies,
    I have already checked and recongnized that a OK arc pin hadn't been connected, but I did'nt found the wiring diagram for a OK arc output with Cpmpact THC SD (proma) in your guide. The THC is seem to be not have a OK arc signal output. Should I need to configurate a output on the MK3 BOB like the picture to connect with a OK arc pin of the hypertherm source?. Could you please to show me?.

    The 45XP has the ArcOK signal in its cnc connector. It has nothing to do with the THC.
