Selector keeps jamming with a small bit of filament
Got the MMU2S installed on the Mk3s, I can do a single-color print again, but any time I've tried a multicolor, the selector jams with a little bit of filament, then acts as if it moved to position 2, pushes the second color filament out to the right of my selector. It would be easy to unjam, if I could simply get the selector motor to spin the selector back to the left side. There doesn't appear to be an override to just reposition that motor, unless I remove power and then I can spin it by hand.
I've tried a variety of combinations of the L/C/R button to no avail, is there a command hidden in the menu somewhere that'll let me reposition the selector motor without trying to reload/unload other filaments?
Thanks
Retraction problems
I see this myself occasionally. In theory, it should not happen - the FINDA sensor should recognize when the filament has retracted out of the selector. Check the FINDA sensor. Also make sure the filament retracts easily through the PTFE tubes at the back of the MMU2S.
I will FINDA way...
Yeah, the FINDA was fine...I had some stringing on filament change, upped the temp to 220 and now I'm about 44% of the way through a sheep, just wondering if there's a way to adjust that motor position if it happens again....It's a real pain to fix if it happens mid-print, and even when it's not mid-print, I have to disassemble quite a bit of the MMU2S to fix the issue, when "move half an inch to the left" would let me clear it with ease.
