Disassembly Guide
Some steps in this document are only for demonstrating operation actions, and some images may have continuity errors. Please focus only on the specific operations and ignore the continuity errors.

Step 1: Lower the Heatbed
Lower the heatbed via the screen, ensure the hotend is at room temperature, then turn off the printer.

Step 2: Remove the PTFE Tube
Press the pneumatic connector on the top of the toolhead to disconnect the PTFE tube above the toolhead. Push out the pneumatic connector of the filament buffer and press to unlock it. Pull the PTFE tube out of the cable chain. Then unlock the pneumatic connector at the filament inlet on the back of the printer and remove the PTFE tube.

Step 3: Remove the Hotend
Refer to this tutorial to remove the hotend https://wiki.bambulab.com/zh/h2s/maintenance/replace-silicone-sock-and-hotend

Step 4: Remove the TH Board
You can refer to this Wiki to remove the TH Board. You only need to follow the steps up to disconnecting the Feeder Hall Sensor connector—there is no need to disconnect the TH Board from the USB-C cable. https://wiki.bambulab.com/zh/h2s/maintenance/replace-th-board
Pull the cable out of the cable chain bracket.

Step 5: Remove the Part Cooling Fan
Refer to Step 3 of the Part Cooling Fan disassembly and assembly guide: pull the cable out of the cable organizer clip and remove the Part Cooling Fan.

Step 6: Remove the Hotend Heating Assembly
Refer to Step 4 of the Hotend Heating Assembly disassembly and assembly guide:
Take out the Part Cooling Fan cable and Hotend Heating cable from the cable management slot;
Remove the 3 screws of the Hotend Heating Assembly, then take off the Hotend Heating Assembly and the gray heat shield;

Step 7: Remove the Toolhead Camera
Refer to Step 5 of the Toolhead Camera disassembly and assembly guide:
Pry open the Toolhead Camera cover and unscrew the 2 exposed screws (one screw requires inserting the screwdriver under the flat cable). It is recommended to loosen Screw 1 by a few turns first, then fully remove Screw 2, and finally fully remove Screw 1.
Remove the flat cable from the toolhead frame. Note that the flat cable at the clip may have adhesive backing in some batches—you need to wiggle it left and right to loosen it.

Step 8: Remove the Hotend Fan and Eddy Current Coil
Refer to Step 5 of the Eddy Current Coil disassembly and assembly guide to remove the Hotend Fan and Eddy Current Coil.
Remove the 2 screws of the Hotend Fan and take off the Hotend Fan; (This is only for demonstrating the operation—there may be continuity errors, please ignore)
Remove the 2 screws of the Eddy Current Coil and route the cable around the area indicated by the arrow; (This is only for demonstrating the operation—there may be continuity errors, please ignore)
Take out the Hotend Fan cable and Eddy Current Coil cable from the cable management slot in sequence, then remove the old Eddy Current Coil; (This is only for demonstrating the operation—there may be continuity errors, please ignore)

Step 9: Remove the Extruder Unit
Refer to Step 6 of the Extruder Unit disassembly and assembly guide to remove the Extruder Unit.
Subsequent steps are only for demonstrating operation actions and may have continuity errors—please ignore them.
Since the FPC cable of the Extruder Unit has adhesive backing and a 90-degree bend (especially the thin Feeder Hall Sensor cable), extra care must be taken when removing the Extruder Unit to avoid tearing the cable.
Peel off the adhesive backing of the cable from the middle frame in the direction opposite to the middle frame.
If the Extruder Feeder Hall Sensor cable is stuck to the plastic middle frame, move the cable first to separate it from the middle frame. If the top motor cable is in the way, use a plastic tool to press it down.
Wiggle the Extruder Unit left and right, then pull it out from the front.
If the sensor cable or motor cable interferes with the middle frame, gently press it down with your finger or a plastic tool; do not pull hard.

Step 10: Remove the Belt
Unscrew the 2 screws on the Belt Holder and remove the Belt Holder.
Remove the Belt Holder on the other side using the same method.

Step 11: Remove the AP Cable Organizer Cover
Use an H2.0 hex key wrench to remove 1 fixing screw (BT2.6x8), then take off the AP Board Cover from the side near the front door.

Step 12: Attach Non-Marking Tape to Both Sides of the Linear Guideway to Prevent Slider Balls from Falling Out
Attach non-marking tape to both sides of the toolhead. If no non-marking tape is available, attach paper to the linear guideway and secure it with transparent tape. The purpose of this step is to restrict the movement of the toolhead and prevent it from sliding off the linear guideway when the guideway is removed.

Step 13: Remove the Linear Guideway Assembly
Use tweezers to assist in removing the LED light covers on the left and right sides.
There is a reserved hole in the middle of the frame. Insert an L-shaped hex key wrench through this hole to easily remove the linear guideway screw on the top of the carriage.
Remove the linear guideway screw on the other carriage using the same method.
Then remove the 4 screws on the side of the linear guideway and the 2 screws at the bottom of the carriage.
After removing all screws, move the carriage back and forth to remove the linear guideway. When removing the guideway, first disengage the right-side guideway from the carriage, then disengage the left-side guideway from the carriage, and finally take out the guideway at an angle.
