Set your extruder to the correct printing temperature of your current filament. (Example: 230 degrees Celsius for PLA). This is so that any remaining filament heats up and can be detached from the extruder.
Wait for extruder to reach the defined temperature.
Once it has reached this temperature, press on lever, and carefully pull filament out, removing it from extruder. Avoid touching the heater needle or heater block as this could result in burns.
