¶ 1. Tools:
S2.0/2.5/3.0 Allen Key
Gloves
Lubricating Grease
¶ 2. Disassembly Steps:
Note: Some illustrations have omitted the bottom heated bed components for clarity.
¶ Step 1: Turn Off the Device
Before replacing the lead screw, ensure that the device is turned off and disconnected from the power source for safety.
¶ Step 2: Move the Z-Axis
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.
¶ Step 3: Remove the Lead Screw Fixing Plate
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.
¶ Step 4: Disassemble the Lead Screw Bearings, Synchronous Pulleys, and Timing Belts
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.
¶ Step 5: Loosen the Coupler Set Screw
Use the S2.5 Allen Key to loosen the set screw on the coupler. Once loosened, the lead screw should be movable.
