What happened?
The Prusa CORE One and the Original Prusa MK4/S and MK3.9/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 consecutive failed loads and unloads, the printer shows the message "Printer has detected multiple consecutive filament loading errors. We recommend checking Nextruder main-plate".
Error name: Maintenace failure warning
Error code: #31116 (CORE One) #26116 (MK4S) #13116 (MK4) #27116 (MK3.9S) #21116 (MK3.9)
How to fix it?
Follow the MMU3 regular maintenance guidelines, in particular the steps related to the Nextruder main plate.
