XController - Stepper motors make some huming

Found this duplicated post… will try increasing the amps per channel to a little more.

Motor hums When not in use

Not sure what is going on. When motor isn’t in use it has a low pitch hum, as soon as it triggers it works fine and the hum goes away until it stops moving again. I have checked the wires and nothing seems to be loose. Any Suggestions would be great.

If Someone has another suggestion, please let me know!
