That's funny, I have similar problems with my swing motor only it goes real smooth one way and sort of glitchy and noisy the other. I had problems at Cabin Fever briefly with it not working at all but I'm pretty sure we were experiencing a brown out in the building because one of the CNC vendors had problems with his mill almost crashing the table. I've been fooling around with my motor drive settings (Dead Band,IR Comp. Response) Another thing happening is my swing won't stay centered from time to time and if I re bind the DX7 again that fixes it for a while. I've never tried putting capacitors on the motors like the lower voltage ones everybody uses because I'm running 90VDC motors and I don't know what uF capacitor to use. A week ago I bought a used line conditioner voltage regulator and we'll see if that takes care of possible voltage drops.
