I am fighting the same problem: TMC2209 with Nema17, CoreXY printer. At certain speeds (~40mm/s) and its multiples I get strong vibration of the motors. Cleaning up the wiring, tuning the stepper drivers, adding damping motor mounts did not help.

@PXP11
Did exchanging the motors improve anything or have you figured out something else to fix the problem?
