Introduction
All the tools you need are a 2.5 mm hex key, a 8 mm wrench, and around 10-15 minutes of your time!
What you need
Step 1
Setting the nozzle temperature
- Press the knob to enter the marlin LCD menu and turn it to navigate between the options.
- Navigate to Temperature > Nozzle.
- Adjust the nozzle temperature by turning the knob and confirm by pressing it.
- Use whatever temperature you would be printing with, minus about 10°C. For both PLA and PETG 210°C usually works fine.
