MMU2S Issue
Hi I have had my MMU2 for several months and I was getting this error randomly but now its every print.
and I could use some help fixing it or suggestions on what to do next.
When my MK3s is printing weather it be multi material or single it will stop mid print and on the MMU2 is will flash all the lights and stops the print, sometimes its with just the red lights and others its with both green and red light that flash.
sometimes it will say the MMU2 needs attention others it just sits there and I have to power the printer off just to get it to do anything.
I have checked and re-calibrated just about everything on the machine with no luck.
re-flashed firmware on MK3 and MMU2 older and newest version no luck fixing it.
Checked and re-calibrated the sensors, tried turning off the sensor on the settings,
Ran it stealth mode and normal mode on both printer and MMU2 still same issue.
I emailed Prusa support and they gave me a link to the trouble shooting guide which I tried with no success.
Here is a video of what it does.
Personally I think the MMU2's have issues with the boards or firmware and it needs to be addressed soon by Prusa.
Thanks

I'm having exactly the same issue. I've been printing 2 colour prints for the last 10 days without issue but last night halfway through the print MMU error and all lights flashing. I checked the power settings and they were 23.7V/23.8V. The G-code is the same one that has been printing for the last 10 days without issue

In which state was the printer? (loading/unloading/position of the filament ...).

RE: MMU2S Issue
I recently learned from support that the best firmware for the MMU was actually 3.7.2. This had never been relayed to me. I am having several issues with Eisny board complaining about error in static memory. Basically response I got was the printer is out of warranty. I will get with developers and see what they say...
I expect that to happen (holds breath)

I'll look into the 3.7.2 later, talking to support now and testing a few thing before going back to older firmware again.
