This sort of inconsistent table travel is likely to be related to the Electrical conversion process rather than any mechanical issues, to test for sure unhook the motor and rotate the pulley by hand if the pulley moves smoothly without any "grabbyness" the problem is almost certainly the electricity convertor, Sorry.
Unbalanced phases apply a kind of two steps forward one step back to the motor's torque output, which really bounces the gears against each other which seems to amplify the backlash vibration. Normally backlash isn't an issue except where the drive is a "reversing" one, and even with a planer table drive that reverses at each end of the stroke the lash should only show up as a clunk.
