¶ 1.Shaft does not move after clicking zero
¶ （1）Check if the motor cable is loose or detached, or if it is plugged into the wrong port.
¶ （2）If there is no abnormality in the wiring, test by exchanging the drive of the non-moving shaft with the drive of the extruder under power-off condition. If the non-moving axis can move normally when you click "Extrude" after the exchange, it means that there is a problem with the driver of this axis. You can contact the after-sales e-mail address: service@flsun3d.com
¶ 2.Axis keeps going up without stopping after clicking home
¶ （1）When you push the axis to the top manually, check whether the light of the limit switch will go out or not; if the light of the limit switch will not go out, it means that it is the problem of the limit switch, you can contact the after-sale mailbox to deal with it: service@flsun3d.com
¶ （2）Whether the socket of the limit switch is loose or detached, or whether it is plugged into the wrong port.
¶ 3.Shaft rotates in the opposite direction
Check if the motor wires are plugged in backwards (only happens after replacing the motherboard or replacing the motor)
