The printer reported a nozzle jam.
I am able to manually feed filament through the print head just fine, used a different color so I could tell that the original filament was completely flushed out.
However, when using the AMS, it feeds to the head, then retracts, does this 5 times, and reports “Failed to feed the filament into the tool head”.
What could cause this? When manually feeding it does grab the filament and push it through.
Is there maybe a sensor that might have failed?
Hoping for a quick reply - otherwise I’ll start disassembling.
Thanks in advance -

Hey Dan,
I had this issue yesterday and it turns out a small piece of filament broke off in the connector that joins the AMS to the the printer. Take it off from both PTFE tubes and check that it’s clear. If not there, make sure the path from the AMS to the printer is clear.
Hope this helps!
Had the same problem… i run a print with PLA and W-Support. Every time the printer changes back
to PLA, same behaviour as you described with messsage “Failed to feed the filament into the tool head”
I can solve this only if I manually feed out PLA and cut the Filament end at an 45 degr angle so the end is not flat and put the Fila back into AMS. Now the Filament was correct feeded and the print resumes.
I think that the filament cutted from the Filament cutter (cuts at 90 degree angle!) stucks anywhere in the extruder or at Filament sensor. It was really annoying, every change of filament i have to take the fila out and cut the end at an 45deg angle, but it worked for the whole print. Now i had to disassemble the printhead and have to see where the palce of stuck is. Best way is if BAMBU Lab places the filament cutter so that the filament is cutted NOT in a 90 deg manner…
If not cut square it is much more likely to deflect sideways and jam below the extruder gears instead of pushing the previous filament into the heat break.
Thousands of people have no problem feeding from the AMS so you have some misalignment or damage or blockage in the filament path from the AMS that you need to fix.
My X1CC is brand new, so i assume it is ok.
hmm…yes i understand your argument, but i have tried it >50 times. At 90 deg cut, 48 of 50 times, stiff filament like some PLA sorts will stuck and rejected by the AMS. If i cut them around 45 deg, i had 100% success… The problem is not pushing the old filament because this is done in a guided way in a hose, so it cannot be deflected. Stiff filament like some PLA is never straight, it is bent because it is rolled down from a spool. It “scratches” along the PTFE tube way and if it stumbles on a resistance like an edge of a pushfit or similar, the filament will stuck. If the Filament is cutted with an angle (must not be 45deg, around 30 deg would also do!) the filament finds its way because the smallest resistance is the way it should go…

Thousands of people don’t have the problem so that is a bad assumption.
No it isn’t. The old filament is cut just above the heat break. The new filament is not well guided after the extruder gears and has to hit the end of the old filament and push it into the hot end. The gap between extruder gears and heat break is where TPU often deforms and clogs because there is no guiding there.
What is wrong with the assumption that a brand new X1CC ist working and without any fault???
Maybe you telling us that your brand new printer isn’t working would be a clue?
What is right about your assumption that the printer has a design fault and should be cutting filament at an angle because you have a problem when thousands of other people don’t have that problem?
And why do i have 100% success if i cut the Filament at an angle and many falses If cut at 90 deg?
I have the same issue and could not figure it out at all. Did you find a solution?
Btw not trying to stir any ■■■■ up but assuming a brand new product to be in working order is expected? So what, you’re suppose to assume all products you purchase doesn’t work? Why buy it in first place.
I have the same issue but the filament feeds to the tool head perfectly, it then pulls it all the way back to the AMS and then goes back into the tool head and repeats. It then reports a nozzle/extruder clog. I just got my AMS and I’m not sure what the issue is. It’s also VERY loud.
Welcome to the forum.
Most likely you have a piece of filament stuck in your extruder. Here is the wiki article detailing how to clean out an extruder clog.

Thank you but while I wish it was that simple, my extrude is unclogged and I am even currently printing with it, without the AMS.
I am getting “unable to feed extruder” error on only the 3rd AMS slot. It repeatedly messes up every time I need to add green layers. Every other color runs consistently, no errors. The green filament reaches the extruder head, then it pulls it all the way back to the AMS, then repeats this until it might extrude. But there’s nothing apparently wrong, I took the AMS apart, nothing stuck in there, I cannot reach the printer head while printing unelss there’s another way to? Maybe move it from home and must I turn it off and lose a perfectly fine model print?
I have the same problem, did you solve this problem?
