Hi guys;
I finally had to give up last night turn off the lights monitor and quit
for the day. The computer got so sluggish I couldn't get anything done
although the emc background would keep running for a minute or so after I
stood on the esc key.
My program is only about 70 lines of code

look at %wa should be 0 if its a high percentage its probably using

Just to follow up on this earlier post.
But, I'm taking a bit of a wild guess and thinking that you are only
driving ONE of the motor's two phases.
This was indeed what the problem was.
Using the method Jon suggested (below) we found there was no power
coming into one phase of the motor.

driving the spindle with an MPG would allow EMC2 to tap a hole in manual

Would be, if EMC2 actually geared to the spindle ;)
You wouldn't be able to do the 1/2 turn forward/1/4 turn back method
though.
(which would have been much much easier
using the hobbing setup should allow the spindle to drive a linear axis
instead of rotary axis then MPG tapping is possible

I have had exactly the same experience as Gene. I was using the Oword code
for making multiple parts (Xmas ornaments) this past winter. When I use the
touchoff to set the X then Y then Z workpiece origins, I had to go through
