Gecko G340 Smoothness

Have my mill moving again with the Gecko drives and as usual have a
question.

I have some motor noise at low speeds (5 ipm), more than at the
rapids I am getting. (80 ipm) I can see the table screws pause as
they turn (very short stop starts) so I may have some acme screw -
bronze nut stop/start friction. I looks like a stepper motion.

More info:
The drives are in the 5x setting and about 4000 steps/in so the
encoders are putting out about 20000 steps/inch.

Any one (Tim? Mariss?) have an opinion on whether changing to the 1x
mode would make the motion smoother, assuming I can coerce EMC into
pushing out the steps fast enough?

P.S. The burn table conversion ( EMC and Dan Mauch's G340 servo box )
I have previously posted about is working well!
