MMU2 all 5 LEDs flashing green
I have an MMU2 with the MK3 and have had quite a few issues setting it up. My latest issue happened after the bowden length calibration. Upon restarting the printer I now have all 5 LEDs flashing green.
I does not appear here https://manual.prusa3d.com/Guide/Status+LED+indications+explained/762?lang=en
What the heck does this mean and what do I do about it? Right now I am unplugging the MMU2 and printing the old fashioned way. Also, why isn't there a way to disable the MMU2 in the printer's UI?
Any help would be appreciated. Also what are the possible combinations and what do thye mean? Since the unit is a new product and still has lots of issues it would be helpful to know this stuff.

FYI, after trying a number of things, pressing and holding the left button seems to have gotten it to complete it's self test. It would still be nice to know what all the status light combinations mean.

I think when you power up initially, if the FINDA senses filament it will simply flash. I would make sure all your filament is withdrawn from the MMU2 and see if that fixes it. If not, unscrew the festo at the MMU2 and use a piece of filament to ensure no debris or string is holding up the FINDA.

Thanks! It would be helpful if all these were written up. It’s a very spare interface. I’m sure you know, display screens are so cheap now you guys should really pay more attention to UI and user experience.

Yup. On power up or reset if FINDA detects filament (or the ball is stuck high with a string) the MMU lights will flash red. When the FINDA then untriggers, it will flash all lights green - a reset is possibly the best solution.
