MMU not responding
Hi everyone,
I've been using my MK4S and MMU3 for about a year now and it's been fairly okay.
Today my MMU gobbled up some filament again. I took some of it apart to clean it up.
Now my MMU doesn't really do anything. When I power everything on, I see the LEDS glow green (4th is orange), and then it changes to #1 being green.
But when I try to push the buttons on it to change the position, it doesn't work, it just stays there. I tried to load filament via the printer but again, nothing happens it just stays on buffering.
Are there any tools I can use to debug what is wrong? I'm trying to figure out what parts I should order to fix it.
Here's what I've tried/seen
* I've turned it off, left it off for 10+ minutes, and turned it back on. I have not tried completely unplugging it, I will do that tonight.
* Everything is plugged in, I've taken it apart again to examine it and it looks fine. I've tried taking things out and plugging them back in.
* When I was cleaning it originally, I pulled out the Selector Motor (#13 here https://help.prusa3d.com/article/mmu3-regular-maintenance_682693)
Maybe I pulled it too hard and yanked the wires? Is there a way to test?
* I did have the power on while doing some disassembly. Maybe that caused a part of the circuit to be damaged? Is there a way to check?
Let me know if I can add anything that will help.
Thank you,
