Step-by-Step Disassembly Instructions
Process Overview
Here is a quick visual flow of the disassembly steps for your reference:
Step 1: Power Off → Step 2: Remove Outer Casing → Step 3: Disconnect Wires → Step 4: Disassemble the Extruder
1. Power Off
Before you begin, turn off the printer and unplug it from the power source. This step is crucial for your safety, preventing potential electrical hazards and protecting your machine from accidental damage.
2. Remove the Outer Casing
Use the H2.0 hexagonal wrench to unscrew the four screws on both sides of the outer casing.
Gently lift off the outer casing along with the logo rotating plate, taking care not to force anything.
3. Disconnect Wires
Carefully unplug the extruder motor wire, cutter wire, and filament detection wire. Take note of their placements for easy reassembly.
4. Disassemble the Extruder
Loosen and remove the three screws securing the extruder to the printer frame.
Once detached, press the tube connector and gently pull out the PTFE tube.
Slide out the damaged cutter and set it aside.
Step-by-Step Installation Instructions
1. Install the New Cutter
Insert the new cutter into its designated position.
Tip: Ensure the side with the notch on the blade holder faces downward. An incorrect orientation may cause uneven cuts or filament jams, affecting print quality.
2. Reinstall the Extruder
Flip open the cutter rod before reattaching the extruder.
Test the cutter push rod by pressing it gently to ensure it rebounds properly. A smooth rebound indicates proper installation.
3. Secure the Extruder
Tighten the three screws on the extruder to ensure even pressure and stability.
4. Reconnect Wires
Plug in the extruder motor wire, cutter wire, and filament detection wire. Neatly organize the wires to prevent tangling or obstruction.
5. Replace the Outer Casing
Align the logo rotating plate and outer casing correctly.
Secure the casing by tightening the four screws on both sides.
6. Reinsert the PTFE Tube
Push the PTFE tube into the connector until it clicks securely into place.
