    In my latest build, I'm driving some of the OpenBuilds high-torque NEMA 23 steppers with a 12v supply and an xProV2 board. I've noticed that they seem to run really smooth at high speeds (5000 mm/min) but very rough on low speeds (250 mm/min). On low speeds, there is audible vibration.

    Is this normal? Or is there some setting I ought to change? I could change the microstepping setting, increase the voltage of the power supply, or maybe even change the controller board. Any suggestions?
