I think that voltages, when output is true are ok, but I think that
there is something wrong with the false state.
Am I missing something here?

Hello, folks!
I would appreciate some advice on servo tuning.
I have Keling Nema23 BLDC servo motors attached to Mesa 7i39.
And also zero experience with this :)
The way I am doing the tuning is:
1) start Emc, hit F1 and F2;
2) open Machine - Calibration;
3) change P value, for example, from 1

I have been playing only with P parameter so far, following this guideline:
1) increase P up to the moment, when motor becomes unstable;
2) add I to make it stable;
3) add D to make the loop stiffer;
This is wrong, you add D to make it more

The relay was my first idea, but it turned out pretty quickly that

Viesturs,
it seems to me that your laser diode is just acting as a normal LED,
not as a laser. This state is only achieved at a very distinct point up
on top of the voltage/current curve. The laser diode supply electronics
must take care of this which

Is there perchance an adjustment potentiometer? The LM317T is a linear
regulator device and could be made adjustable so as to compensate for the
wiring and switching loss in your controller.
Nope, I see 2 resistors in series for the middle leg.

If not you may somehow have lost encoder counts, this should be checked
Try mode h and comment-out the rawcounts lines, that ought to make

Sounds encouraging :)
More likely that you have either run out of headroom (what is the motor
voltage vs supply voltage?) or you have a commutation problem. Commutation
problems will happen if you have
