¶ Step 3: Remove Print Head Casing
Use the S2.5 Allen Key to loosen the 2 screws securing the print head casing.
¶ Step 4: Remove Print Head
Use the S2.5 Allen Key to loosen the 2 screws securing the print head. Move the print head to a position where it does not interfere with the pulley removal.

¶ 3. Installation Steps:
¶ Step 1: Install Pulley
①Place the sheet metal on the X-axis aluminum profile. Install the pulley on the print head sheet metal. Pre-lock the screws with the previously removed nuts.
②Secure the nut with an open-end wrench and use the M3.0 Allen Key clockwise to tighten each screw.
③Slightly shake the print head module. If there is noticeable wobbling, use an open-end wrench to adjust the hex eccentric spacers on the back of the fixed pulley until the print head module no longer wobbles, and moves smoothly on the X-axis.
¶ Step 2: Install Print Head
Place the print head ribbon cable in the cable slot, then use the S2.5 Allen Key to loosen the 2 screws securing the print head.
¶ Step 3: Install Print Head Casing
Align the print head casing with the screw holes on the sheet metal. Use the S2.5 Allen Key to tighten the 2 screws.
¶ Step 4: Install X-axis Belt
Install the belt copper buckles on both sides of the X-axis sheet metal.
¶ Step 5: Adjust X-axis Tensioner
Turn the knob on the X-axis tensioner clockwise until it is tight, then loosen it counterclockwise by one turn.
¶ 4. Re-run Auto Bed Leveling:
After replacing the X-axis pulley, perform auto bed leveling again. If there are issues such as the nozzle pressing too hard on the bed or a too large gap, manually adjust the Z-axis offset.
