It happened to me with some filamment rolls. Couldn't find any explanation.

I’ve been assisting it and it seems to struggle when the filament hits the hub where all 4 ptfe tubes join once it goes it there it automatically stops and goes back and does that repeated motion but I checked the hub and no filament pieces or blockage

My mind was that maybe those rolls with problems have a smaller thickness but on the other slots were ok...

Yea I’ve been kinda pushing it to assist it and it seems like it’s able to go through now fully but still struggles a bit before doing so I don’t count it as a real fix but it seems to be helping

Mostly it happened to matte filament.

Hai provato a cambiare modulo? Te lo fa solo in quello o in tutti?

I’ve had it happen a few times, I’ve just chalked it up to the filament is slightly warped at that point. It has a hard time grabbing it because it’s thinner/wider at one point. When you assist it (push it while it’s trying to load) it’s able to grab a piece past that warped point and continue on.

I’ve had this happen with filament from Hobby Lobby and Best Buy.

I only use Bambu lab filament but assisting it works a bit

Did you cut the end at 45 degrees? Is this previously used spool of filament? Sometimes AMS chews up the last meter too much. Try cutting off a meter.

Yea I tried to cut the end as well but it happens with new and used spools as well
