MMU selector not homing properly
I've had my MMU for a couple weeks now and have had varying degrees of success with multicolor prints (occasional feed issues but for the most part it has worked alright). Today I started having a new issue (after completing a successful single color print): the selector doesn't seem to be homing properly. After I turn it on and it finishes its startup sequence, there is a gap between the selector and the left wall, which means it doesn't line up with the filament path. If I turn it off and turn the lead screw by hand it moves freely to the end and lines up properly, and I'm able to hand-feed filament into it without issue.
I've tried power-cycling it several times, turning the lead-screw by hand with it turned off to make sure it moves freely all the way to both ends (it does), checked to make sure there were no rogue bits of filament hiding anywhere, made sure nothing came loose or printed parts cracked... Everything seems to be fine. I'm stumped. Any ideas?
Re: MMU selector not homing properly
Ignore this thread. 🙄 Turns out the filament I have loaded into the first position is curved just enough (due to being towards the end of that spool) that it bangs into the side of the selector's entry point. I guess moving it by hand a bit made it line up with that curve, which is why I assumed it wasn't homing properly. Straightened it out as best I could and it's feeding properly now.
