The few times I've had different counts re' direction it has been a
broken flex coupling to the encoder.
Of course it could be that you are simply running out of frequency
response. Not likely but possible.

Wasn't in there, put it in and rebooted.
Now I am re-calibrating the servo_scale which will take an hour or more.
I snapshot the encoder count at 1.0 turns of the home-switch, snapshot
the counter at 101 turns, subtract the first count from the second to
get the diff, div that by 100 to get 1 turn, and divide by 360 to get
one degree. Or just div by 36000. I am also suspecting I'm missing a
count, at g0 speed, 1800 degrees a minute, the dro is losing counts,
worse in one dir than the other. I *think* that's a separate problem.
Thanks Phil T. Stay safe and well.
Cheers, Gene Heskett
