Unload filamentare often unnecessary, as the printer will load and unload filament to/from the nozzle when it needs to.
Load filamentoption in the menu and then select the MMU slot you would like to load filament into. The MMU will then move the requested slot and ready for loading. Gently feed filament into the tube until you feel the MMU grab onto it, and then let go and wait for the MMU to finish the loading process. Use a light touch for this, it can be difficult to tell when the MMU has grabbed the filament otherwise.
Eject filamentoption in the menus and then select the material you will be ejecting so the MMU can preheat. Once it is done preheating, the MMU will move the selector out of the way of the filament slot and push filament out of the front of the MMU. Cut the end of the filament off so it doesn't get stuck in the tube and then retract the filament by pulling on it from the spool end. Replace the spool when done.
