Step 1: Remove the Power Supply
To make it easier to remove the power switch and the screws located at the bottom of the right inner lining, begin by removing the power supply. Lift the transparent protective cover upward, then use a cross-head screwdriver to loosen (but not completely remove) the screws securing the power cables. Pull the cables downward to detach them. Next, use an H2.0 Allen key to remove the two fixing screws (BTW3x6). Finally, open the power supply from the left side—where the screws were removed—and lift it out of the printer.

Step 2: Remove the Power Socket
Use an H2.0 Allen key to remove the two screws (ST3x8 marked in red and BT3x8 marked in green), pull the power socket diagonally out of the inner lining, and press the buckle to disconnect it from the power safety key base.

Step 3: Disconnect the Heating Block Power Cable
Push back the insulation sleeve and press the buckle to unplug the heating block power cable from the AC board, then use an H2.0 Allen key to remove the buckle’s BT3x12 screw and release the cable from the clip.

Step 4: Remove the Right Inner Lining Unit
Use an H2.0 Allen key to remove the three right-inner-lining screws (one ST3x8 and two BT3x8), free the top motor wire and hall sensor cable from their slots, then pull the lower edge outward to release the two buckles before pushing the lining inward and lifting it out of the printer.

Step 5: Separate the Inner Lining Upper Cover-Right and Chamber Heater Unit
Lay the right inner lining flat, remove the seven BT3x8 screws with an H2.0 Allen key, pry off the nano glue joining the upper cover and Chamber Heater Unit, lift the upper cover to separate the two assemblies, and—without rotating the servo—flip the cover over and remove the four BT4x32 screws to take out the Chamber Heat Circulation Fan if replacement is needed.
