Clean the tabletop. You're going to be laying your printer on its side to take off the case. So avoid scratching it all to heck, like I did. Take the time now to brush all those little filament bits off the table and maybe even put down a towel as padding, like I didn't.

Remove the white filament cover plate on the right side of the printer.

Unload your filament using the screen prompts.

Turn it off then unplug your printer.
