Materials Needed:

• New filament spool
• Ender 3 V2 3D printer
• Tweezers or needle-nose pliers (optional)

Steps:

1. Preheat the Printer:
   • Turn on your Ender 3 V2 and preheat the nozzle to the printing temperature of the filament you want to remove. You can do this through the printer’s menu.
   • Wait for the nozzle and bed to reach the desired temperature. The exact temperature depends on the type of filament you’re using. Common temperatures are around 200°C for PLA and 230°C for ABS, but consult the filament manufacturer’s recommendations.
2. Retract the Filament:
   • In the printer’s menu, navigate to “Control” and then “Retract.” This option will retract the current filament from the hotend.
3. Cut the Filament:
   • Once the filament starts to retract, use a pair of tweezers or needle-nose pliers (if needed) to assist in pulling out the filament. Cut the filament near the extruder gear, leaving a clean end.
4. Unload the Filament:
   • Continue to retract the filament until it’s completely removed from the hotend. You may need to manually feed the filament to help it come out smoothly.
5. Load the New Filament:
   • Take your new filament spool and trim the end to create a clean, pointed tip. This will make it easier to feed into the extruder.
   • Insert the new filament into the filament guide tube, if you’re using one, and then into the extruder. Push the filament gently until it reaches the hotend.
6. Load the Filament:
   • In the printer’s menu, navigate to “Control” and then “Load.” This option will engage the extruder gear and push the new filament through the hotend.
7. Watch for Extrusion:
   • As the new filament feeds into the hotend, watch for filament to start extruding from the nozzle. This indicates that the new filament has replaced the old one.
8. Calibrate Your First Layer (Optional):
   • After changing the filament, it’s a good practice to recalibrate your first layer height by adjusting the bed leveling knobs. This ensures proper adhesion to the print surface.
9. Begin Printing:
   • With the new filament successfully loaded and extruding correctly, you can start your 3D print job as usual.
10. Store the Old Filament:
    • Coil and store the old filament in a sealed bag or container to prevent moisture absorption.

By following these steps, you can easily change the filament on your Ender 3 V2 3D printer and continue with your 3D printing projects using different types or colors of filament.
