XController - Stepper motors make some huming

I upgraded to XController and tuned my stepper motor current limit using a voltmeter. When the machine homes after it halts movement it makes some humming noises on some random axis.

I tuned the controller after leaving it alone to factory settings.

I did wired both y motors independently

One thing I noticed is that if I try to move the steppers. BY hand it doesn’t take too much force to do it when the motors are energized. I don’t know if this is normal.

I am guessing micro stepping issues.

I am using NMEA23 motors that came with my original kit.

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

If Someone has another suggestion, please let me know!
