¶ 2. Disassembly Steps:
¶ Step 1: Power Off the Device
Before replacing the Y-axis pulley, ensure that the device is powered off and disconnected to ensure safe operations.
¶ Step 2: Remove the Hotbed
① Remove the spring steel from the hotbed and place it aside for subsequent installation.
② Use the S2.5 Allen key to unscrew the 6 screws securing the hotbed.
There are spacers between the hotbed and the hotbed bracket, so please avoid losing them when removing.
Place the hotbed and the bottom spacers aside for subsequent installation.
Note: Since the hotbed wires are not disconnected, place the hotbed within the movable range.

¶ Step 3: Disassemble the Y-axis Tensioner
① Rotate the knob of the Y-axis tensioner counterclockwise and remove it, placing it aside for later installation.
② Use the S2.0 Allen key to unscrew the screws on both sides of the fixed Y-axis tensioner housing.
Remove the housing and place it aside for later installation.
¶ Step 4: Remove the Y-axis Sheet Metal
① Disassemble the belt copper buckles on both sides of the front and rear of the hotbed-fixed sheet metal.
Remove the pulley from the Y-axis tensioner and place it aside.

② Slide out the hotbed-fixed sheet metal from the direction of the Y-axis tensioner.
¶ Step 5: Disassemble the Y-axis Pulley
Use an open-end wrench to fix the nut, then use the S3.0 Allen key to counterclockwise unscrew the 4 spacer screws securing the pulley.
Remove the pulley, screws, spacers, and nut.
¶ 3. Installation Steps:
¶ Step 1: Install the Y-axis Pulley
① Take out the new Y-axis pulley and install it with the previously disassembled screws and spacers.
② Install the newly assembled pulley assembly onto the Y-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.

¶ Step 2: Install the Y-axis Sheet Metal
① Slide the Y-axis sheet metal in from the Y-axis tensioner. Ensure that, during the sliding process,
the side of the sheet metal with the "notch" faces the direction of the touch screen (see the yellow-marked part in the diagram).
