While I was looking for the wiki site to post the screenshots, Jeff
identified
the problem. I was reading the encoder input and processing it, both in the
servo-thread.
Now the spindle-velocity is dithering about 15% to 20%, which is
approximately the deviation on the encoder pulse widths. Appearently this
is normal, based on comments on the net.
Do you know the wiki website address for EMC posting (for the future)?
I let the trash can eat it.
Thanks again for all your help
Don
