How does the MMU 2 work?
I didn't really know what the buttons and lights all did when I first built the MMU2, but I was able to figure out with trial and error how to get it to load, unload, switch, unjam, etc.
I really did look for a complete guide, but this thing is SO new that there isn't one place to find all of the info.
But with the new firmware, I have no clue how to load filament or even more the selector. What do these lights mean?
This document is out of date, or mine is broken: https://manual.prusa3d.com/Guide/Status+LED+indications+explained/762?lang=en
I can't get the selector to move, so I thought it was an unplugged motor or something electronics, but I just pressed a button and it moved. I have no idea what I did, or how to do it again.
Can I get one document for all that the MMU2 does with the current firmware?
Re: How does the MMU 2 work?
I just took it apart again and swapped the idler and selector motor and the selector motor moves just fine. I think I have an intermittent problem with the stepper driver for the selector motor. I reflashed the firmware v.1.03 too. no luck.
Funny thing though, I just downgraded the MMU firmware to 1.0.2 and it moves again!
Please help.
