What happened?
The Original Prusa 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 consecutive failed loads and unloads, the printer shows the message "Printer has detected multiple consecutive filament loading errors. We recommend checking the extruder".
Error name: Maintenace failure warning
Error code: #28116 (MK3.5S) #23116 (MK3.5)
How to fix it?
Follow the MMU3 regular maintenance guidelines and the regular printer maintenance guidelines, in particular those related to the extruder components.
