Help with Proma 150 and Mach3

Post by tas99 » Tue Mar 24, 2020 9:07 pm

I have a Proma 150 and Mach 3 and when in Proma test mode I can see the Torch On, TorchUp and Torch Down signals operating correctly on the Diagnostic Screen but the Z of the torch never moves.

Is it supposed to move up and down in Test Mode?

I think I've enabled THC in Mach3 properly but does anyone know all that should be done to get it to run?

Any help would be greatly appreciated.

Tom

It has been a long time since I used a Proma, try making the HYS voltage higher that may give you a longer time for the proma to move. And that would give you a longer time for each function. Again not sure.
I have this image from back then try that check box on I know I have seen the Z move up/down, but cannot remember what setting made is happen.

I have that box checked along with THC on the Program Run screen as well as Allow THC UP/DOWN Control even if not in THC Mode.

Thanks for the video.

I tried it with and without that box checked, no difference.

The THC up and down signals are being seen by Mach3 because I can see the THC lights (up/down) alternate on the diagnostic page in sync with the up/down signals from the THC I just don't see any corresponding up/down movement on the Z/torch head.

Have you actually performed a cut with the THC, since you have seen the indication in Mach it may work fine. Set the HYS voltage to 1 volt so you will see movement of the torch with small changes for testing. Cut about a 6 inch line and you should see if things are working, just watch the Z DRO for movement.

I haven't actually run the plasma cutter yet. I'm in the process of finishing the water pan which is the last item and I'll give it a test run then and let you know what happens.
