MMU2 flashing green-red?
I'm not seeing this mentioned in the docs, but the printer is stuck on the purge tower, was probably trying to change filaments and something went wrong (I guess) because the filament it should change to was showing a red light. So I pressed the middle button while making sure the filament was being loaded, but after moving back and forth a bit it now flashes green-red (short green, long red). Any idea what that means?
Re: MMU2 flashing green-red?
Red/green flashing indicates the issue has been corrected and the MMU is waiting for the right button to be pressed to resume the print.
Read page 29 section 12.4 of the MMU handbook (V1.01) for the meaning of the LEDs and the actions to take to correct the issue.

Re: MMU2 flashing green-red?
Aaah, you're right but boy that's buried deep in the text. There should really be a single table/list explaining all the possible flashing LEDs and their meaning in a single sentence (perhaps with references to the chapter where they are explained further).
Thanks for the help!
Re: MMU2 flashing green-red?
Ended up in this topic because I had the same issue. In the current version of the MMU2 manual it can be found under 12.3 instead of 12.4
If the procedure finishes correctly, the LED above affected filament will turn to red-green flashing
[...] press the right button to continue the print
I also found a document about the MMU2 LEDs, for future me and other people ending up here.

Re: MMU2 flashing green-red?
the solutions posted for the slow flashing green and red hasn't solved my problem.
if you could get back to load filament this problem may be fixed but you cant get back unless you cancel. I don't want to cancel the print
Re: MMU2 flashing green-red?
no filament was in the Bowden tube it was unloaded. I've had to restart print
Re: MMU2 flashing green-red?
After re setting. I reloaded all the filaments and It loaded as normal. To be able to get back through the menus to be able to do that would be a very easy fix. According to the book it was ready to load the next filament but nothing happened.
