Hi Craig,
That's interesting. Seems I need to do a little more research on the topic of THC and Mach4. Hmm... maybe it is a case that my trusty old THC300 is not yet supported by the Motion Controller PMDX 422 rather than Mach4 not being THC compatible...
I have viewed a few video's on Youtube that show guys running a plasma set up on Mach4 and also some suggesting that the proma Compact THC150 is a solution that works with Mach4, but as you said, its a case of the TH controllers working in with the motion control board (and that motion control board communicating with Mach4 right?) rather than the software as it is/was in Mach3.
Hmm... ok, so looks like I either need to chat with the team at PMDX to see if they have THC on the to-do list (no doubt they have and likely a case of when) or throw more money at my setup and get a Vital setup...
IT would be a pity to not be able to use the PMDX-422 board and the THC300 given that I already have the gear and in the case of the THC300, spare boards. But, if it ain't gunna work, it ain't gunna work!!!!
Cheers,
Marcus
