here is what helped me:
just slightly adjust the Y potentiometer by turning it clockwise by a small amount until the Y-axis moves smoothly at rapid speeds (link when moving a long distance while Z is retracted on a large job)
Do not over-torque these pots - they are tiny and gentle and will break. The pots have 270 degrees of rotation.
See here for more detail:
Edit: The pots are usually set at 50% and I just had to tweak mine to maybe 60%
