My specific problem is that when I turn the controller on, as soon as the splash screen on the LCTHC closes and goes to the voltage screen, the torch on circuit fires and stays on. The red light on the front panel comes on, TOR shows on the LCD, and I can hear the relay click on the sensor card. In Mach diagnostics, torch on is not "on", and in fact the same symptom occurs even if I start the g540 with parallel cable disconnected. It is not being triggered by Mach despite Tom's instance that the only thing that can trigger torch on is Mach.
I know the candcnc is a well respected company, and that Tom is the driving force behind that, but I found him to be less than helpful (or even pleasant) considering that the specs on the LCTCH say that they offer 60 days free phone support and unlimited online support.
Regardless, I am not giving up! I know it can work, and I will get it working one way or another.
Again, thanks for your time and I am sorry to have gone on so long!
