Galil / Re: Mach 3 - Galil DMC 4030 - Proma THC - No THC action
« on: October 21, 2019, 10:08:47 PM »
I probably will not be any help to you but I too have a Proma THC and a home made plasma table.  I am using mach4 and going through a PMDX-416 to the proma and from the proma to the stepper controller.  With it wired like the drawing shows in the Proma manual I have control of the Z axis when the torch is off and the Proma is powered up.  When the torch is on the Proma moves the Z axis and the cnc (mcah4) does not know the actual position of the Z axis.  I guess that is about as controlled as I am going to get.  I also have tried the Proma set up as a standalone device outputting to the z axis and it controls that way also.  Of course when the Proma is wired for stand alone I can never move the z axis from the cnc. 

Are you using the Proma THC-SD then?  I may look into that and see if there is a way to pass control back and forth to the THC with a relay and another output.  I need Z control to zero before the cut. 

Galil / Mach 3 - Galil DMC 4030 - Proma THC - No THC action

I have a Plasma table (Esab Ductcutter Retrofit) with Mach3, A Galil DMC4030, and a Proma 150 Compact THC Torch height controller.

The THC Test mode shows the IO working correctly in the Mach display, but no actual movement on Z. I've tried several different mach configuration combinations and none seem to make a difference. When THC is enabled, the Arc OK portion functions correctly, but still no up or down of the torch. Can anyone with Mach3 and the Galil motion plugin confirm that THC actually works with it?

I had the Galil THC plugin installed at first, and had to remove it to get the Arc OK and IO to show up correctly, as that plugin is intended to take arc voltage directly into the controller, not Up/Down signals (As far as I can tell at least, discovered after some more fumbling around in forums).

Thanks in advance
