To replace the filament on the Bambu Lab X1, please follow the steps below.
A video is also included to help you with the process.
The printer will begin heating up the hotend, then will proceed with cutting the filament. A confirmation will show up on the screen when the process is complete.
You don't want the filament to get tangled. We also recommend using the small holes on the sides of the spool to keep the filament in place.
It will make loading the filament easier. Ensure that the filament doesn't get loose on the spool, to avoid any tangles.
Press it multiple times, until the new filament color is clear and the old filament is purged.
