Replacing the thread puller

Here is a step-by-step procedure for replacing the thread puller on your 3D printer, following the video tutorial provided:

STEP 1: TURN OFF THE PRINTER

• Before starting any maintenance, make sure your 3D printer is completely turned off and disconnected from the power supply to ensure safety during the process.

STEP 2: PULL OUT THE NYLON TUBE

• Press down on the quick-release ring located on top of the extruder.

STEP 3: UNPLUG THE 8-PIN CONNECTOR

• Detach the 8-pin connector located on the wiring harness between the thread puller and the top of the printer.

STEP 4: CUT THE CABLE TIES

• Using scissors or a wire cutter, cut the plastic cable ties that hold the thread puller cables in place.

STEP 5: REPLACE THE 3 RUBBER BANDS

• Remove the 3 green/clear rubber bands from the old thread puller.
• Replace the old thread puller with the new one.
• Insert the green/transparent rubber bands into the three pins located at the top of the new thread puller.

STEP 6: INSERT THE NYLON TUBE

• Insert the nylon tube with a diameter of 6 mm into the quick coupling located above the extruder.

STEP 7: RECONNECT THE 8-PIN CONNECTOR

• Reconnect the 8-pin connector to the wiring harness between the thread puller and the top of the printer.

STEP 8: REPLACE THE CABLE TIES AND CABLES

• Reposition the plastic ties and cables as they were before maintenance.
