If that were the case I would expect the ripples on the "Y" side to vary, based on the speed of the previous move. That’s what I thought too, before I did these tests.

Slowing down eliminates this, as does making the acceleration slower so the transition is less harsh. There are other things you can do too, like tightening the belts (if they're loose) or switching to reinforced belts that stretch less. Personally, I would slow down the acceleration. I hope that's useful.
