Before switching filament or doing any maintenance, you'll need to unload the current filament first.
Use this when you need to fully retract and remove the filament from the printer — for example before storage or when replacing the spool.
When loading a new spool — after first setup, when switching colors, or after a nozzle swap.
Your printer arrives pre-calibrated. Only follow these steps if prints are warping, not sticking, or shifting during printing.
