New maker kit latest firmware and Ground control.
Z-axis makes Left motor hum. No noise from Z motor.
I read another troubleshooting post here where OP was using webcontrol with a similar issue and solved by turning off Diagonal in webcontrol settings.
I loaded up Webcontrol and made sure diagonal was off. I tested motor and the Z-Axis motor made a high pitched Morse code sound for 1/2 second and stopped. No movement.
I’m starting to think it’s a bad Z-axis motor.
