The THC-300 board fires the torch through a relay. Yes, this had worked prior to adding the THC, I was running the torchmate software when I first got the machine a few months ago though. When I added the z-axis and swapped out the motors/controls I started using mach and had it running before messing with the THC although I did not run a lot of programs through, maybe 10-15. I was thinking it working before adding the THC-300 and completely disconnected the unit, wired the torch on directly to my breakout board and remapped the torch on in mach to correspond. I then cut a test program of four 4" circles, about a 8 or 9 times without issue. So, i'm pretty sure there's some issue with my THC-300 unit, i've dispatched a post on the yahoo forum for the THC-300. Thanks.
