Hi, I am new to the forum. I have a proma THC I was using with another setup and an independant THC head with a DC motor - worked well but I wanted to cut the wight down on the Z so I figured I'd feed the PROMA outputs into MAch3 and just use the z axis stepper to perform the Torch height control. Ah well, not so easy. I have nothing but high end computers in here and not a parallell port in sight so I went with a smoothstepper via USB. The THC did not work but I had not yet purchased Mach3 and figured that was the problem. Once I was sure I could get mach3 to do what I wanted, I bought it. It is now licensed and THC still does not work. So after about 6 hours of research, I found an obscure note on a forum where a fella said that the THC function is part of the Parallel port driver in Mach3. This makes sense because you would want quick control. Well since I have a smoothstepper, I don't use that driver. Very disapointed. Back to my old DC motor setup which worked well but it's a bit bulky because I have a gas torch as well as a plasma head and planning to put a touch probe so getting ugly. I really need the probe because my bed is 12 feet long and I load 3 different plate sizes and they aint allways flat as I'd like.
Oh well
Anybody know if that guy was right about the parallel port driver doing the THC work?
