Not very quiet motor, why?

noob question, I have this motor Nema17 bipolar 0.9 degree controlled by a 8825 driver, so far so good, the problem is that when doing microstepping (1/32 steps) the motor makes high frequency sounds, you can see it in action here, is it normal? is there anything I can try to make it run quiter?, suggestions will be appreciated. Thanks in advance.


That noise doesn’t seem unusual, though it is hard to hear it really well through a recording or get a sense of how loud it is. What frequency is your step signal? Could you post more details about your system like the supply voltage and current limit setting?
