¶ 1.Tools:
M2.5 Allen wrench
¶ 2.Disassembly Steps:
¶ Step 1: Turn Off the Machine
Before replacing the Y-axis motor, turn off the machine and disconnect the power source for safety.
¶ Step 2: Disconnect the Y-Axis Motor Cable
Refer to the diagram below and disconnect the Y-axis motor cable.
¶ Step 3: Loosen the Y-Axis Tensioner
Turn the red knob on the Y-axis belt tensioner counterclockwise to loosen it. This will make it easier to install the new Y-axis motor.
¶ Step 4: Remove the Y-Axis Motor
Use an M2.5 Allen wrench to remove the 4 screws that secure the Y-axis motor, and then take the Y-axis motor off.
¶ 3.Motor Testing:
Take the new Y-axis motor and plug its cable into the motor connector. Connect the machine to the power source and turn it on. On the main screen, click on "Tools" > "Move Axis" > "Y-axis zero."
Observe whether the new Y-axis motor rotates normally. The machine's control screen may display an error message: "Y homeing failed，please check the Y endstop and 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
①Install the new Y-axis motor onto the Y-axis sheet metal (Note: When installing, ensure that the belt is completely engaged with the Y-axis motor synchronous pulley gear, and the Y-axis motor cable should be facing downward).
②Take the 4 screws previously removed from the Y-axis motor, and using an M2.5 Allen wrench, pre-lock each screw one by one. After pre-locking all 4 screws, finally, tighten them. Note: The yellow-marked location should have the ground wire inserted onto the screw before securing it to the Y-axis motor. Ensure that the ground wire position is within the range of the sheet metal recess, as it can interfere when installing the Y-axis limit switch cover later.
¶ Step 2: Install the Cables
Insert the Y-axis motor cable into the Y-axis motor connector.
¶ 5.Adjust the Belt Tension:
Turn the Y-axis tensioner knob clockwise to tighten it all the way, and then rotate it counterclockwise one full turn.
After replacement, please re-level your printer.
