¶ 1. Tools:
S2.0/S2.5/S3.0 Allen key
Gloves
Lubricating grease
¶ 2. Disassembly Steps:
Due to the need to rotate upward during the replacement of the Z-axis lead screw,
it is more convenient to disassemble the lead screw from the anti-backlash component when the lead screw at the bottom of the anti-backlash component is shorter.
Therefore, it is recommended to zero the Z-axis before disassembling.
¶ Step 1: Zero the Z-axis
Power on the printer, go to the main menu, select "Settings," click on "Move," and then click on "All Home" or the "house" icon on the right to zero the Z-axis.
¶ Step 2: Turn off the device
Before replacing the Z-axis lead screw, make sure the device is turned off and the power is disconnected for safety.
¶ Step 3: Remove the top bearing fixing shim of the Z-axis
Use an S3.0 Allen key to unscrew the top bearing fixing shims on both sides of the Z-axis,
remove the bearing fixing shims and the gantry's top aluminum profile, and place them aside for later installation.

¶ Step 4: Remove the synchronous wheel and belt
Use an S2.0 Allen key to remove the 2 screws on any side of the Z-axis lead screw synchronous wheel, take off the synchronous wheel and Z-axis synchronous belt.
Place all removed parts aside for later installation. If no lead screw is exposed, try rotating the synchronous wheel to expose it.
Disassemble according to the number of lead screws that need to be replaced.
If you need to replace the lead screws on both sides, you also need to disassemble the synchronous wheel on the other side in the same way.
