Removing the X-Axis Assembly / Toolhead Carriage Assembly
Step 1: Remove Components from the Toolhead
Refer to the following Wikis to remove the toolhead shell, hotend, hotend heater assembly, and hotend fan: https://wiki.bambulab.com/en/p2s/maintenance/replace-hotend-heating-assembly-and-cooling-fan
Refer to the following Wikis to remove the cutter handle and extruder assembly: https://wiki.bambulab.com/en/p2s/maintenance/replace-filament-cutter-lever and https://wiki.bambulab.com/en/p2s/maintenance/replace-extruder-components
Refer to the following Wiki to remove the TH board and extrusion interface board: https://wiki.bambulab.com/en/p2s/maintenance/replace-th-boards-and-fpc-cable Then disconnect the drag chain mount and remove the toolhead cable and drag chain from the carriage.

Step 2: Remove the Belt Clamp
Use an H2.0 hex wrench to loosen the four tension screws (only 1–2 turns; do not remove them) to release the XY belts.
Use an H2.0 hex wrench to remove the three screws securing the belt clamp, then take off the belt clamp. Repeat the same steps to remove the belt clamp on the opposite side.

Step 3: Remove the Toolhead Carriage Assembly
Use an H2.0 hex wrench to remove the eight mounting screws. Hold both the front and rear covers of the toolhead carriage, slightly tilt the front cover first, then remove the carriage carefully to prevent the four springs at the top of the front cover from falling out.
The following steps are only required when replacing the X-axis assembly.

Step 4: Remove AP Board Cover
Refer to this Wiki to remove the AP board cover from the frame: https://wiki.bambulab.com/en/p2s/maintenance/replace-ap-board-cover-and-led-light-left

Step 5: Remove Printer Housing

Remove the AP board cover and left side panel: https://wiki.bambulab.com/en/p2s/maintenance/replace-left-side-panel
Remove the adaptive airflow switching assembly and right side panel:https://wiki.bambulab.com/en/p2s/maintenance/replace-right-side-panel

Step 6: Remove XY Belts
Use a hex wrench to push the belt clamp slightly outward, then remove the belt clamp from the belt to take the belt out. If the belt is loose, you can push the belt directly to remove the clamp without using the hex wrench. Pull the belts on both sides of the X-axis and remove them from the two Y-axis carriages.


Step 7: Remove the X-Axis Assembly
Use an H1.5 hex wrench to remove the four screws securing the outer panels of the Y carriages, and take off the panels from both the left and right Y carriages.
Rotate the X-axis assembly diagonally across the printer and remove the X-axis assembly.
