I Recently got my new Bambulab X1C, i now got Problems with my Sunlu Pla+ Filament in Port 3 of my AMS. Sometimes not everytime, when the AMS trys to retract the Filament when a colour change starts, it gets stuck. And the display says that the AMS is jammed. When i then go to “try again”, and slig…

I had the same filament and same problem. It turned out the roller by the retractor gears and up slightly. I had to snap it back into place. It is difficult to see if it is up or not. I posted a thread about it here in the forum with a picture showing it.

I have the same problem with the 3erd Slot aldo a filament that works in the second now doesn´t work in the third and viceversa the ona who get stuck in the third, works fine in the second. Now I read this and I pull out the rollers and put it again in the other way and I´m trying it now…I hope it …

So this is happening A LOT. Always the third slot. I have participated in at least 3 threads on Reddit. Here is one: Reddit - Dive into anything Someone in support or manufacturing should be looking at this. I checked the rollers, they are fine.

Same here, got stuck towards the end of a 16 hour print while I was at work, by the time I could retry (wasn’t stuck) the part had cooled enough to make an ugly layer shift, ruining the print

My number 3 also doesn’t feed correctly most times either. It will fail on retraction, and I will have to move spool a tiny bit backwards to trip sensor, and when feeding back into machine, it will often need a boost to start the feed. Not at all usefull when trying a multi color. Support tickets …

I had the same problem in slot 3 only with Bambu PLA-CF black. Moved it to slot 4 and no problem. Dried it thoroughly in filament dryer, RH down to 15%, and no longer a problem in slot 3! Prior to that, pulling the P tube from left side of hub seemed to temporarily fix the problem; retraction comm…

This does seem to be a recurring problem with slot 3 as I just had a jam with a brand new printer on its fourth print. I had printed with Bambu PLA in slot 1 and printed the Benchy fine, I also printed the extraction tool and that was fine too. I then printed the Benchy with eSun Silk in slot 4 and …

I also had this problem in slot 3. When I took the front wheels out I noticed that the bearing near to the gear did not sit properly on the axle. There was a significant resistance when turning it. I pushed it around and to the middle, it snapped a little and then rolled freely. No problems in sl…

I’ve had this in Slot 3 and 4 with multiple filaments. Filed a support ticket with Bambu. It happens at the end of the print job and the spool gets yanked up off the rollers and it stops. I have a video but I guess we can’t post links or videos here :expressionless:
