i have a bit of time for this as i have a dead Hybrid motor but id rather get it ready before the new motor shows up.

If your belts are exactly the same length, are routed correctly, and you have no other loose parts vibrating: Are your belts tight enough? I found that if I move the gantry all the way to the rear, with tool heads parked, and I pluck the belts like a string instrument, they should both vibrate at around 100Hz. This is just a ballpark number. Your mileage may vary. A phone audio spectrum analyzer app might help.

Hmm, the belt runs might not be the same length on a single toolhead machine like they are on IDEX. So your belts might be a different frequencies.
