To replace the filament on the Bambu Lab P1P, follow these steps:
¶ Video Operation
¶ 1. Select the 'Unoad' option on the screen. The printer will begin heating up the hot end, then cutting the filament automatically.
¶ 2. After completing the second step, carefully pull out the filament while re-spooling it on the filament spool. This operation must be done; otherwise, unloading cannot be completed. You don't want the filament to get tangled. We recommend using the small holes on the sides of the spool to keep the filament in place.

¶ 3. Select ‘Retry’ to repeat the process if you didn't pull out the filament.
¶ 4. Bambu Lab P1P load filament on spool holder | Bambu Lab Wiki
That's it! Now you can start printing!
In the current firmware version, 01.02.02.00, the "load" / "unload" buttons can cause a layer shift. This issue will be solved in the next firmware.
For 01.02.02.00, we advise not to use the "load" / "unload" option, for example, when changing filament during a paused print. You can use the extruder "feed" and "retract" buttons on the printer screen or in the Handy App.
