Paul ,
  Try switching the X-axis cable with the Y. If the problem occures on the
Y-axis then you can rule out gib or screw problem. If the problem stays with
the X-axis then check that the gib oilers are clear and adjust gibs. Some
manufactures have you adjust gibs with a volt meter hooked in series on your
amp, you adjust the tension according to the amp draw when the axis is
moving at a set feed rate, on my Hurco it is 40ipm, I preprogram  the
machine to run back and forth for full length of travel, because of machine
wear amps will vary, I set them so at the ends your amps hit the high side
of amp draw. Check that the ball screw is oiling, if not it could signal
worn out balls on the screw, one other problem would be the trust bearing on
the screw is bad, if so hold on to hat, they are $$$$, e-bay for that one, I
saved $250 for the set.
    As far as the amp, the manufacture probably gives you setting like turn
CCw to stop then CW 20 turns, etc... that would be the last adjustment I
would make, check that bandit doesn't have their our recommendation on the
settings. Also did take out the brushes in the servo? Make sure thy are good
and blow out the servo to get out carbon dust. If you servo have tach feed
back, check those brushes as well.
Hope this helps,

Thanks Richard.
