5 flashing lights

Hi all,

I'm new to the Prusa world, but I need to become an expert for my job. We have the MK3S and the MMU2s kit that was installed before I got here. For the life of me I couldn't get the MMU to load and print. So I took it off and was able to print different materials without the MMU just fine, so the problem is with the MMU and not the printer. Today I decided to put the MMU back on, it seemed fine until I went to load filament. The selector/FINDA probe won't move at all, and without having filament near the MMU the 5 flashing red lights happen. It boots up normally, clicking sounds when it turns on and all, but won't do anything when I try to load filament. If anybody has any sort of insight as to what's going on, I would appreciate it greatly.

Hello! To me it sounds like there is either filament inside the FINDA, or the FINDA probe itself is not properly adjusted. See this video for more info:

agreed.  5 orange/red lights means something is in the selector.   if they are orange/red and green, the manual says that's a power issue.
