How to update the Prusa MMU3

Download the firmware for your exact printer from help.prusa3d.com/downloads.
Copy the .bbf (MK4, XL, Core One) to a USB drive, insert it, and confirm on the printer.
Or use PrusaSlicer's firmware updater over USB for older MINI and MK3 boards.

Always download firmware from the manufacturer or project itself. Firmwarely links out; it never hosts firmware.
