Description: This guide's intention is to solve problems...

Steps:

1. Press the knob to enter the marlin LCD menu and turn it to navigate between the options.
2. Navigate to Temperature > Nozzle.
3. Adjust the nozzle temperature by turning the knob and confirm by pressing it.
4. Use whatever temperature you would be printing with, minus about 10°C. For both PLA and PETG 210°C usually works fine.

5. Wait until the current temperature (bottom) matches the target temperature (top).

6. Press down on the extruder lever arm and pull out the loaded filament.
7. Fully pressing down the lever arm might lead to the filament snagging when you try to pull it out. Just pressing it a bit will usually suffice.

8. Navigate to Temperature and press Cooldown.
9. If you do not have the Cooldown-option available, you can just repeat step one and set the temperature to 0°C instead.

10. Use a 8 mm wrench or some pliers to unscrew the PTFE tube from the extruder mechanism.

11. Unscrew the single M3x18 socket head screw with a 2.5 mm hex key.
12. Remove the extruder arm and spring.

13. Use a 2 mm hex key to remove the three remaining M3x10 socket head screws while making sure to not let the motor drop.
14. Remove the plastic bracket and the motor.

15. Install the replacement extruder and screw it to the motor, following all the previous steps backwards.

16. Reattach the PTFE tube to the extruder and insert some filaments.
