Ok, now EMC starts up and seems to be fine.
I have one more question:
Which of the pins should I connect pid.n.output to?
There are 3 value pins, one for each phase:

hm2_7i43.0.3pwmgen.00.B-value
hm2_7i43.0.3pwmgen.00.C-value

One recommendation is to put a Vee cutter in your spindle and run a program
where the Vee bit just touches the material in a uniform grid pattern. Take
your part and measure all the positions from the 0,0. You may have your

Hi Marty,
As other people pointed out, it might be better not to jump to conclusions the
cause of the error may not be stepper calibration.
