Hows it going everyone !

Thanks for tanking the time to read my post. At higher RMP's the stepper NEMA 34 Stepper motor seems to run just fine. But at lower RMP's (500mm/s) natural frequency of the stepper motor seems to resonate throughout the machine. It sounds like it is going to vibrate itself apart. It just sounds wrong. The stepper motor is coupled to a threaded rod. I dont know if thats what is causing this really strange noise but I am assuming that something is wrong with the stepper motor driver. If any one knows a good source to learn about these kind of stepper motor drivers that would be super helpful.


Happy Friday !!
