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.

I'm in SLC and in the process of banging together a mendelmax, the makerbot tom just wasn't cutting it anymore. But seriously that is just incredible. That is an amazing print!

That pcb is a thing of beauty! Any chance you would put a price on cutting another one? Maybe I'm just jealous of another man's toys, but I really like the look of it. Would thinner traces = less wattage needed? Wow! That pcb is a thing of beauty! Any chance you would put a price on cutting another one?
