So the problem here is that CNCDRIVE motion controllers eg UC400ETH do not support more than one mpg.

I see what you mean but in the mpg setup in mach3 it only has port/pin settings for A and B.

General Mach Discussion / Multiple MPG encoders MACH3

Hi I'm hoping someone can steer me in the right direction.

I am setting up a mill.

Mach3 (licensed), Win 10, UC400ETH motion controller.

I have installed 2 mpg's one to control the X and the other to control the Y.

MPG1 A and B are connected to port 2 pins 10,11
MPG2 A and B are connected to port 2 pins 12,15

In port/pins config I enabled mpg#1 and mpg#2 and set the relevant pins and ports.

Then in function config I ran mpg calibration it worked correctly for mpg1 but it will not read any movement from mpg2.

On the settings tab MPG diagnostics MPG1 shows pulse and velocity, MPG2 shows nothing.

I opened the jog control and ALTA & ALTB have leds lit for X and Y. Setting the jog mode to MPG allows MPG1 to control axis X correctly, but MPG2 does nothing.

If I go back to ports and pins and disable MPG1, MPG2 will now work.

It seems I can only have one MPG at once connected but I'm sure that I must be missing something.

Any ideas?

I have found the problem.

The 2T 4T switch on my plasma cutter has failed and is stuck in the 4T position.

This means that holding the 'trigger' for 10 seconds sets the machine to constant cut!!!!!!

Thank you for your time helping me, it has been very much appreciated.

Thanks for looking. It seems that m157 has no effect.

General Mach Discussion / Torch remains ON after cut

Hope someone can help me here.
I set up this plasma table a year or two back, then it has just recently started to operate incorrectly.

The torch will turn on and off using the torch on/off button and it will turn on and off if I type m03 and m05 into the bar.

But when a program runs, the torch remains lit all the time.

I assume I must have changed something in my config but can't see it. Then I used a backup config file and still the same.

The machine is a plasma cut table UC400eth motion controller. A simple relay turns the torch on and off. I think its connected to output 1.

I have attached my xml and an example of a file that is failing.

Could you tell me how to find these files?
