¶ 3. Disassembly Steps:
Note: The images below are for better illustration, taken by disassembling the print head from the entire device.
It is not necessary to remove the entire print head during actual disassembly. Some accessories in the images may be missing, but the steps remain consistent.
¶ Step 1: Turn Off the Device
Before replacing the extruder motor, ensure that the device is turned off and disconnected from the power.
Wait for the print head temperature to cool to room temperature for safe operation.
¶ Step 2: Disconnect Extruder Motor Cable
Disconnect the extruder motor cable.
¶ Step 3: Disassemble Print Head Casing
Use the S2.5 Allen key to loosen the 2 screws (located on the back of the print head) that secure the print head casing.
Since the print head casing and the model cooling fan (FAN0) are integrated, remove the FAN0 cable from the groove before pulling out the cable.
