MMU3 Won't load to Super Pinda
Filament seems to be getting stuck right before entering the selector. I can push filament through and out the end just fine from the other side, but it simply will not load filament into the selector. I've already taken out the selector and checked it for damage, but no luck.

Does the idler motor turn and align the bearings according to the filament position OK?
Is the pulley motor turning the pully's? Check and tightened all the pulley grub screws to make sure they are not slipping?
Also ensure all PTFE tubes are fully pushed and seated into position.
Can you verify the system is grabbing the filament when you load it and pulling it towards the selector?

So I did some "troubleshooting" waiting for your reply. If I push the filament selector a little to the left it is able to grab filament #1 and after that it also successfully grabs all other filaments. However, this method is not 100% reliable and whenever the selector rehomes, it homes itself in the wrong position again, theres no visible damage, but I'm strongly considering reprinting the whole thing lol. The issue originally started when filament got stuck during cutting, keeping the selector from moving. After that, it hasn't homed correctly even once.
So, to answer your questions:
Idler is correctly aligning itself, all pulleys are turning without slipping (until it pushes against the selector body (instead of the hole)) All PTFE tubes are properly seated. When initially loading filament, it sometimes doesn't get grabbed properly if the filament is too bendy, but otherwise it's fine.

Filament also seems to be getting stuck right after the filament sensor on the selector and sometimes before
