I don't expect that the backlash will be an issue since the loop is
closed twice. It is closed between the motor and drive and for
position between the table and control. If I force the table 0.0005
off position, it slowly rotates the leadscrew until the position
error is 0.0000.

When I get closer to getting this project underway, I may contact you
for help getting EMC working with my machine, and perhaps come by to
see your machine & controls.

Thanks!
