MMU2S What do the buttons do.

The MMU2S has three buttons can anyone explain what they do.  I have read the description in the manual but it doesn't match what I experience.  It seems that the buttons have different functions at different times.  In particular pressing the left button doesn't always move the selector left, the right button doesn't always move the selector to the right and the middle button doesn't alway feed the filament.  Originally I thought the MMU2 controller was bad but the replacement doesn't act any better.

I dont know all the functions but when its not printing you can use the "left and right buttons"

to switch from the different filaments positions 1-5 and if you press and hold the middle button while on the filament position you want it will start the loading processes for that filament.

 

I rarely use the buttons, mainly use the printer and let it control the MMU2

It is all documented in the handbook. Just read it.

I can't find anywhere in my handbook which gives functions of the buttons, just labels them as left, middle, and right.

RE: MMU2S What do the buttons do.

What I have found is that when MMU fails to load/unload a filament the center button repeats the last action (so you can se where the problem is), once solved (the lights turns flashing green and red) you cn start the mmu again with the right button.

With PVA+ I am completing my prints with thi procedure and opening the mmu everyting the filament got stuck. 

I have not found the right settings for PVA+ yet.

Maybe you can find something here. I have had a lot of problems with my mmu2s and found this page helpful. https://help.prusa3d.com/en/article/mmu-needs-user-attention_2139  

There is always hope!...

@lichtjaeger

It would be nice to see this graphic added to the User documentation/PDF. It's been handy - but even with it I am at loss as I'm not sure I understand when to choose 'continue' vs. 'check solution'. Could you give me examples of using this? I especially am confused about which of those to press during the initial Wizard if errors occur at the various states of filament movement while processing the Wizard.  It definitely clears up some confusion as I and others who have worked with this thing around me thought left move filament and right moved it the opposite direction.

RE: MMU2S What do the buttons do.

Finally! I've been looking for such a handy list for a long time, so thank you lichtjaeger!

I want to put the list laminated next to the printer and have therefore created a small PDF. I also put the meaning of the LEDs on it, so I have a double-sided card for reference.
I'm attaching the PDF here, in case someone finds it useful. If you have any comments or corrections - please let me know!
