What happened? 

The Original Prusa MK4/S, MK3.9/S, MK3.5/S can be equipped with an MMU3 upgrade kit. Having the MMU3 upgrade kit installed significantly increases the number of loads and unloads. 

After a set number of loads and unloads, the printer shows the message "Maintenance Reminder. Filament changes have reached main-plate lifespan/have reached 30k. Inspect the part and ensure you have a spare plate available". 

Error name: Maintenace warning

Error code: #26117 (MK4S) #13117 (MK4) #27117 (MK3.9S) #21117 (MK3.9) #28117 (MK3.5S) #23117 (MK3.5)

How to fix it? 

Follow the MMU3 regular maintenance guidelines, in particular the steps related to the Nextruder main plate.
