Todd774,
The MPG has been working fine since late 2015.
It was changed last year from Mach4 Control to Plugin Controller control last year.
The Controller now performs the incremental movements based on the Mach4 settings when in Plugin Controller mode and not simulation.
The MPG incremental accuracy in conjunction with steps per unit determines how accurate it will be.
So if you have a fine pitch BallScrew and high =>10 Microsteps then it moves in finer increments values due to a higher level of pulses.
For example, let’s say you used 100 counts/mm (2540/inch) this means:
0.1mm = 10 pulses
0.01mm = 1 pulse
0.001mm =?

Invalid level of precision
In your case of 10000/inch then 0.01 = 3.9 pulses
You can view this in the diagnostic on your Controller if they show all the motion like HiCON (not sure what the PMDX411 shows).
I presume that 10,000/unit you are using on the Motor settings is in Inches, if so, 20,000/unit or more would be better.
Regards,
Mauri.
