    Stepper motors are moving in the opposite direction when jogging. Please help.

    Which ever motor is going the wrong direction, take one pair of the motor wires and switch them around.

    I assume that was for a Y axis where it was causing the gantry to rack. If not, you can easily change directions in the grbl settings. You can invert the $3 setting for each axis.

    Why do the motors have a humming sound?

    Because thats the normal sound a stepper makes while braked because steppers use pseudo sine waves created by a chopper driver

    Thanks, Peter, for the information. Maybe you can help me with the xyz probe. I can't seem to get it to work on the black box 32X. Any help to resolve this issue is greatly appreciated. I have tried everything except reversing the wires. Not sure if it would damage the black box.
