    Is this working on the bench or on the machine.? . . . . Motors need to be fixed on the machine or Clamped very securely other wise they will be affected by resonance and sound like can of marbles.

    If on the machine then it could be several things. Resonance is the main suspect and Christien hit on the cure by changing the micro steps. Upping the steps will move the resonance to a different frequency which may suit your drives better. This is common issue with cheap drives because of there basic handling of resonance.

    The next common thing is motor phases being wired wrong so check your wiring. Also make sure your signal wires don't run along High voltage wires like mains power or spindle wires etc.

    Is it possible to video the motors running and the noise.
