Introduction
What you need
Step 1
Nozzle
- Turn the 3D printer on using the power switch.
- Move the head to the highest position on the Z axis. This provides working room to access the head.
- Heat the nozzle up. This step depends on what type of filament is currently in the machine (e.g. 190 for PLA, 220 for ABS).
- Remove filament from the 3D printer.
- Clean off the old nozzle with tweezers.
