¶ 1.Tools Required:
M2.5 Allen wrench
¶ 2.Disassembly Steps:
¶ Step 1: Turn off the Machine
Before replacing the Y-axis motor, make sure to turn off the machine and disconnect the power for safety.
¶ Step 2: Disconnect the Y-Axis Motor Cable
Refer to the image below and unplug the Y-axis motor cable.
¶ Step 3: Loosen the Y-Axis Tensioner
Rotate the red knob on the Y-axis belt tensioner counterclockwise to loosen it. This will facilitate the installation of the new Y-axis motor.
¶ Step 4: Remove the Y-Axis Motor
Use the M2.5 Allen wrench to unscrew the 4 screws holding the Y-axis motor, then remove the Y-axis motor.
¶ 3.Testing the Motor:
Take out the new Y-axis motor and plug the Y-axis motor cable into the motor connector. Connect the machine to the power source and turn it on. On the main screen, click the "Settings" icon, then "Move" and finally the "Home" icon inside the circle.
After the X-axis homes, observe whether the new Y-axis motor rotates normally. The machine control screen will display an error message, "Y-axis homing failed, possible reasons: 1. The Y-axis limit switch is abnormal, please check the sensor or wiring. 2. Y-axis motor abnormal, please check the motor or wiring."
This is normal.
If there is no problem, safely shut down the machine and disconnect the power cord and Y-axis motor cable.
¶ 4.Installation Steps:
¶ Step 1: Install the Y-Axis Motor
① Install the new Y-axis motor onto the Y-axis metal plate (Note: Ensure that the belt is fully engaged with the Y-axis motor's timing pulley, and the Y-axis motor connector is facing downward).
② Take the 4 screws that were removed when disassembling the old Y-axis motor and use the M2.5 Allen wrench to pre-lock each screw one by one. Once all 4 screws are pre-locked, tighten them. Note: For the yellow-marked position, you must place the ground wire over the screw before securing it to the Y-axis motor.
¶ Step 2: Install the Cable
Plug the Y-axis motor cable into the Y-axis motor connector.
¶ 5.Adjusting Belt Tension:
Rotate the Y-axis tensioner knob clockwise until it is tightened to the maximum, then rotate it counterclockwise one turn.
After replacement, please re-level your printer.
