Note: Some illustrations have omitted the bottom heated bed components for clarity.
Before replacing the lead screw, ensure that the device is turned off and disconnected from the power source for safety.
Follow the illustration to move the Z-axis by pulling the belt in the specified direction.
Lower the X-axis to ensure that the print head does not touch the heated bed, facilitating easier removal of the Z-axis lead screw in the subsequent steps.
Use the S3.0 Allen Key to unscrew the 2 screws on each side of the lead screw fixing plate.
Remove the lead screw fixing plate and screws and set them aside for later installation.
Remove the bearings from both sides of the lead screw.
Then, use the S2.0 Allen Key to loosen the 2 set screws on each side of the lead screw synchronous pulleys.
Take off the synchronous pulleys and the timing belts between them. Place all disassembled parts aside for later installation.
Use the S2.5 Allen Key to loosen the set screw on the coupler. Once loosened, the lead screw should be movable.
