Filament Change Process

Steps to Change Filament:

1. Preheat the extruder to the current filament's temperature.
2. Unload the old filament by manually retracting it or using the printer's unload function.
3. Load the new filament into the extruder, ensuring it feeds smoothly.
4. Purge the nozzle by extruding about 10cm of filament to remove any residue from the old material.
5. Check the first layer adhesion and adjust bed leveling if needed.

For mid-print filament changes, pause the print, change the filament, and resume. Ensure the new filament matches the required temperature profile.
