¶ 1. Tools:
S2.5 Allen key
S2.0 Allen key
Open-end wrench
¶ 2. Disassembly Steps:
¶ Step 1: Power Off the Device
Before replacing the X-axis pulley, ensure that the device is powered off and disconnected to ensure safe operations.
¶ Step 2: Remove the Print Head
① Pull the Z-axis synchronous belt to lift or lower the print head to the middle position of the Z-axis for subsequent disassembly.
Note: Pulling to the right raises the print head (red arrow direction), pulling to the left lowers the print head (yellow arrow direction).
② Use the S2.5 Allen key to unscrew the 4 screws securing the print head module and place the print head aside.
As there is no need to disconnect the wires and PTFE tube on the print head, the movement range is limited. Just ensure it is within the active range.
¶ Step 3: Disassemble the X-axis Belt Tensioner
① Rotate the red knob on the X-axis belt tensioner counterclockwise and remove it, placing it aside for later installation.
② Use the S2.0 Allen key to unscrew the front and rear 2 screws securing the X-axis belt tensioner and remove the X-axis belt tensioner housing.

¶ Step 4: Remove the X-axis Sheet Metal
① Use a tool to remove the belt copper buckle at the front of the X-axis sheet metal and take down the pulley assembly wrapped by the belt, placing it aside.

 |
 |
② Slide out the X-axis sheet metal from the direction of the X-axis tensioner and remove the X-axis sheet metal.

¶ Step 5: Disassemble the X-axis Pulley
Use an open-end wrench to fix the nut, then use the S3.0 Allen key to counterclockwise unscrew the 3 spacer screws securing the pulley, and remove the pulley, screws, spacers, and nut.
¶ 3. Installation Steps:
¶ Step 1: Install the X-axis Pulley
① Take out the new X-axis pulley and install it with the previously disassembled screws and spacers.
② Install the newly assembled pulley assembly onto the X-axis sheet metal.
Take out the previously disassembled nut, screw it onto the screw, fix the nut with an open-end wrench,
and then use the S3.0 Allen key to clockwise tighten the screws one by one.
