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: Replacing the P2S Hotend Heater Assembly/Hotend Fan
Refer to the following Wikis to remove the cutter handle : Replacing the Cutter Lever
Refer to the following Wikis to remove the extruder assembly: Replacing P2S Extruder Circuit Board 
Refer to the following Wiki to remove the TH board and extrusion interface board: Replacing the P2S Toolhead Circuit Board
Refer to the following Wiki to remove the eddy coil: Replacing the P2S Eddy Sensor
Refer to the following Wiki to remove the extruder motor: Replacing the P2S Extruder Motor

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.

Step 4: Remove AP Board Cover
Refer to this Wiki to remove the AP board cover from the frame: Replacing the P2S AP Board Cover/LED Fill Light – Left
Step 5: Remove Printer Housing
Remove the filament guide bracket, buffer, and rear panel: Replacing the P2S Back Panel
Remove the AP board cover and left side panel: Replacing the P2S Left Side Panel
Remove the adaptive airflow switching assembly and right side panel: Replacing the P2S Right Side Panel

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.

Installing the X-Axis Assembly / Toolhead Carriage Assembly
Step 1: Install X-Axis Assembly
Place the X-axis assembly diagonally into the printer, align the Y carriages with the Y linear bearings, then rotate the X-axis assembly into position.
Note: After installation, check that the edges of the Y linear bearings align with the Y carriages. If they do not, push the bearings to align them. If the bearings protrude too much, remove and reinstall them.
Before installing the panel, check the letter on it: Left = L, Right = R. The panel marked L goes on the left side of the printer, near the left side panel.
Install the left and right panels and use an H1.5 hex wrench to tighten the eight screws (four on each side).

Step 2: Thread the XY Belts
Fold the belt end to make it easier to thread through the Y carriage.
Thread the belt through the idler pulley on the Y carriage as shown in the image below.
First thread the belt through the Y carriage, then through the front idler pulley, and finally through the bottom idler pulley.
Thread the belt through the belt clamp, align the teeth of the clamp with the teeth on the belt, ensuring the raised dot is at the belt’s end. Then pull the belt to snap the clamp and belt together into the belt clamp.
Install the other XY belt using the same method.

Step 3: Install Printer Housing
Install the right side panel and adaptive airflow switching assembly: Replacing the P2S Right Side Panel
Install the left side panel and AP board cover: Replacing the P2S Left Side Panel
Install the rear panel, buffer, and filament guide bracket: Replacing the P2S Back Panel

Step 4: Install Toolhead Carriage Assembly
Before installation, check that the springs are on the front cover of the toolhead carriage.
Align the two aluminum sleeves on the X-axis vertically. Position the bottom of the toolhead carriage front cover against the sleeves, then slowly rotate the front cover until the top of the cover contacts the sleeves.
Next, install the toolhead carriage rear cover and use an H2.0 hex wrench to tighten the eight screws in a diagonal pattern.

Step 5: Install the Belt Clamp
First, install the right belt clamp (near the right side panel) onto the toolhead and tighten the three screws with an H2.0 hex wrench.
Push the toolhead to the rear right, then firmly install the belt clamp on the other side onto the toolhead and tighten the three screws with an H2.0 hex wrench.
Manually push the toolhead carriage back and forth along the XY directions as widely as possible 3–5 times, then tighten the four tension screws with an H2.0 hex wrench.

Step 6: Install Components on the Toolhead
Install the extrusion motor: Replacement of P2S Extruder Motor
Install the nozzle eddy current sensor: Replacement of P2S Eddy Sensor
Install the drag chain mount, connect the toolhead cables and drag chain to the toolhead carriage, then install the toolhead circuit board:Replacement of P2S Toolhead Board
Install the extruder assembly and cutter lever:Replacement of P2S Extruder Components , Replacement of Filament Cutter Lever
Install the hotend heater assembly, hotend fan, toolhead shell, and hotend: Replacement of P2S Hotend Heating Assembly/Hot End Fan

Step 7: Adjust the Eddy Sensor
