      I have a problem with my new Duet Wifi- I can home the Y Axis, but if I try any manual movement, the axis doesn't move (or barely moves.)

      Here's a YouTube video of what's happening.

      I tried M906 and M913 to make sure that the motor was receiving enough current, and it is matching the configured values.

      I thought that the motor is somehow toast, but that doesn't seem consistent with the Homing behavior.

      Any ideas?

        Please post your config.g, homey.g and homeall.g files.

          Here you go-

          homey.g

          homeall.g

          config.g

            Are you sure that you have your 0,0 origin set to the front left corner?

            You may need to verify the direction of your motors.

            Also, you should remove the G92 Z0 command form your home all if you are using a Z probe and G30 to home Z.

            Are you temporarily using an endstop switch for Z?

            What firmware version are you using? I see you have a BLTouch, but you are using P5 as the probe type. Newer firmware versions have a dedicated probe type for the BLTouch. P9.

              I didn't spot anything wrong with your config. From the noise that the stepper motor is making, I think you have the acceleration or movement speed set too high and the motor can't keep up because of the mass of the bed. Try reducing the Y acceleration in the M201 command in config.g, or the Y maximum speed in the M203 command in config.g.
