Hello. Having the same problem at the moment. With a completely new AMS, exactly the same problems arise. The AMS that comes with the printer works very well. Were you able to find a solution?
Hello. Has the new AMS motherboard solved the problem?
Hi. New ams mainboard didnt solve. For me it was the general ams feeder motor.
same here-they had to send me a new one
The ams is getting stuck at the coupler.
What I did was cut a long piece of filament and run it through the tube by hand and see if it gets stuck if so remove the coupler and make sure the ends of the PTFE tube are cut straight and then also make sure the tube is all they way tight in the coupler.
Push that piece of filament back through and if it goes through smooth the the ams shouldnât have an issue.
For me, too, the loading error could be corrected by replacing the filament hub motor. Thanks for pointing this out!
I have the same problem since day 1 with that. Only problem with AMS is after printing the filament is stuck in the tube and i have to diconnect the quick coopling.
Is this caused by the HUB on back from printer or from Motors into AMS? Its dosent matter which ports is using, i get anytime that problem.
I just had this issue with my AMS, only in slot 1. I found that the filament had a bad spot in it. I cut off the filament at the point it entered the feeding slot and pulled out the old filament. Feed it back into the slot and it is now feeding fine and resumed the print that had failed.
My issue was with a glow in the dark filament as well. Never got stuck, but would randomly eject and lock up on AMS. If I waited a few minutes and just retried it woulld work, but stop again a few minutes later. I have two glow filaments that I tried. One was green and it worked fine once I respooled. The other was white that would glow purple. That one would not work in the AMS no matter what.
Have you ever fixed your problem? I have exactly the same on my new X1CC on slot 1 and donât know what to de. Appreciate every help!
Iâm having the issue with port 2. I just got the printer a few days ago.
I find that, if I pull the filament out and cut it with scissors and put it back in, it will feed.
Has anyone resolved the issue? Iâd like to not do that every time.
I have had this problem numerous times and particularly when you have a print with multicolors is worse. I have had situations where I had to abort the prints. I THINK I have found out why this happens. The head of the printer is uppermost when this happens. I have done this- Lift up the glass cover and lift up the ptfe tube so that it is shooting out of the head at 90 degrees and the filament will not retract back.
I think that the problem takes place because the ptfe tube is pressing against the glass top and is sort of bent. when it is straightend up, the filament will stop behaving like this. I am seriously thinking of manufacturing a spacer which fits in between the glass cover and the top to avoid the ptfe tube from bending. please try this out and leave your comments at least I will be sure that I am not dreamingâŚ
Good Morning my Bambu Colleagues⌠I Think I have found the reason and a solution to the issue when the AMS keeps loading and unloading and then pops up a message after doing so several times.
The issue is that the PTFE tube is bent against the glass top. What I have done is I printed a 40mm spacer(done it in 4 pcs and dovetailed. This spacer will fit in the step which takes the glass top and I have provided a recess for placing the glass.
This alone was not enough. The PTFE tube feeding into the extruder has to remain vertical for quite a bit and I have designed a part which fits into the rectangular opening and holds the ptfe tube decently straight. This seems to have solved my problem.
I have no idea how I can share this with STL files and pics. I am willing to share if you leave your e-mail.
Upload the model to MakerworldâŚ
I am going to crazy if i not solve this. I do everything to fix that but notting is solved. I bougt this with my saves and I am upset about it. Pls help.
Hi, bad news. I print the files and assemble but when I send print It did the same issue. I contact with seller but they donât turn me back. When they turn and we solve the problem, I will write here.
I am having a similar issue now with the same behavior of the AMS - the filament is pulled all the way to the extruder and then retracted back several times and eventually it reports an error citing a potentially stuck filament in the extruder. It doesnât matter what AMS slot I use, they all exhibit the same behavior. I can, however, print without any issues from an external spool. To provide more context here, this only started happening after I âfixedâ the AMS from another issue where the AMS filament hub stopped working after I tried using the third slot for the first time. I contacted Bambu support and they figured out it was the filament hub and sent me a replacement part (the original filament hub component had the third slot magnet improperly installed).
That issue was fixed after I swapped out the hub. But then, on the first print test, I ran into this very issue described by others here. It seems that it most likely is related to either wiring between the components in the AMS which I had to disconnect and reconnect, so potentially I caused it by damaging a connector or not fully connecting it⌠I am still troubleshooting but probably without digging into the error logs I wonât be able to narrow it down.
Update: I took apart the AMS again and verified the cable connections and checked that the internal filament hub motor was moving freely at which point I realized that I may have not installed it properly. There are four longer screws holding it, and they are supported by rubber stands through which the screws pass. These rubber stands also are on the other side of the screw holes and need to be seated properly on the AMS frameâs stand for the screws. It may have been that that internal hub was slightly tilted when I replaced it, and for that reason the filament wasnât passing as smoothly through the hub and motor may have been getting a little strained (as per the error). After I made sure it every screw hole was well aligned, tightened it again, and reassembled the AMS fully, the error disappeared and the printer started printing without any issues with all AMS slots loaded. I hope this gives someone another place to check when encountering this error. It did the trick for me.
been dealing with this too. My issue was at the PTFE coupler. I could watch my filament hit the coupler and stop and not make it into the chamber.
Make sure that the ptfe tubing is cut square and inserted fully.
