I keep getting the same error message at the end of a print when I use any filament in the AMS in spot A3. “3DP-00M-041: Failed to pull out the filament from the extruder. Please check weather the extruder is clogged or wether the filament is broken inside the extruder. After troubleshooting, click the retry button.” I troubleshoot it and click retry and get the same error message again.
When I pull the tubing out of the extruder, the filament comes out with the tubing and there are no issues. If I disconnect the tube on the back of the printer, the filament comes out of the printer very easily with no resistance. However, when I try to pull the filament back through to wind it back on the spool manually, there is very high resistance. Even if I push the level on the AMS. This is only happening with the third spot in the AMS. I don’t have the issue with any other spot in the AMS only the one that is labeled A3 on the printer and in Bambu Studio.
I’ve tried multiple filaments and types of filaments during multiple prints and all of them have the same issue if they are in the A3 spot in the AMS. I don’t have the issue with filaments in any of the other spots in the AMS.
Since this issue only happens when I use filament in the A3 spot, it seems to be an AMS issue. I do not have any filament clogged in the extruder or hot end and the filament has no resistance if I pull it out by disconnecting the tube on the back of the printer.
This is a new printer that I’ve only had for a few days and the problem started the very first time I used spot A3 in the AMS. How do I fix this error?
remove the lid of the printer, detach the PTFE tubes to the printhead and push the oversized filament past the PTFE tubes, still stuck start tracing the PTFE back out of the machine and unlock the next section which is the buffer that doesn’t release the tension so you can PUSH the filament through on the AMS side after a few meters snip it off throw it away or recycle. Now clear the failure notification and see if it reloads, keep going if you need to but normally this allows the blockage to be removed without causing a bigger mess or breaking an extruder
I have exactly the same problem with an AMS slot 3. I got the AMS and P1S a week ago. A3 slot always gets stuck and your description of the problem is exactly the same as I have. Tell me if you find a solution.
Thanks for the suggestion. There doesn’t seem to be a blockage.
None of my filament is oversized. All of the filament slides through the PTFE tubes without any resistance. When manually pushing the filament through, the only place with resistance is when I get to the AMS hub. There is no blockage in the PTFE. The filament loads without issue and prints without issue when I switch filament. The only area that has tension or resistance is inside the AMS when I use slot A3 after the print is finished. The filament won’t retract after the print and the area that has resistance seems to be inside the AMS hub. There is no resistance or friction in any of the PTFE tubes before the AMS and no resistance up to the point of the AMS hub inside the AMS. The issue started the very first time I used slot A3 in the AMS.
Cool, trace the lines find the pinch point where the rubbing won’t let the filament retract inside the AMS you’ll find a Wiki full of helpful tidbits of where you’re wrong sprinkled through out its contents, and while you are at it start using a micrometer on your filament they say +/- .2 but its more like .4 depending on the brand, you’ll figure it out
I have the exact same issue on a machine I just go last week, except for me it is slot #3 and #4. The other two work perfectly. All 4 will feed the filament without issue. I have pulled everything apart once already but will do it one more time to check for any blockage or kinks in the tubing again. This is frustrating and preventing me from doing multi-color prints. I have another machine with the AMS that works perfectly every time.
Do you happen to have any bambu filament? Be interesting to see if that also displayed the issue on slot 3. Not saying you should have to use Bambu, just curious. Sounds like a support issue, maybe they can send you a replacement.
It was Bambu filament that was in slot 3 the first time I used the AMS and the first two times I had the error were with two different Bambu filaments.
The filament isn’t rubbing anywhere inside the AMS. It seems to be a problem with the feeder. Pressing the button/lever on the AMS feeder for A3 doesn’t release the tension on that feeder for slot A3.
I submitted a ticket last week on Friday to Bambu Support and I still don’t have a response from them.
How does opening the bottom help me when I already figured out its the feeder for slot A3? There is no restriction inside the tubing in the AMS. Its the actual feeding mechanism where the filament is initially inserted.
Outside of getting a replacement part, I’m not sure if I could fix it.
Is everybody printing with the glass top on? If so do a print with the lid off and see if you have the issue - on mine I have issues with slots 3 and 4 retracting when the lid is on, it seems the angle of the filament pushed from the lid against the PTFE gives too much resistance for the torque on slots 3 and 4 to overcome. You can find prints on printables and makerworld to insert into the toolhead to adjust the angle of the PTFE coming in to resolve as well.
I have had the exact same issue.
But in slot #1 and #3.
It has been many times, maybe 20+ times, and until yesterday, only with with Bambu PLA-CF. Yesterday I had the issue with Sunlu PLA+.
I haver never had cloques, only resistance in the tubes, when pulling back.
Very Strange.
I tried several different filament guides with no resolution to the issue. I also tried printing supports that raise the glass top up higher so that the tubing doesn’t hit the glass and that didn’t fix the issue.
I can’t offer any answers but mine does this too, mostly on 3 but sometimes 4. This is recent though, last few weeks. Previously it worked flawlessly in the 5 months I have owned it. It is so frustrating as I also cannot easily remove the feeder tube at the back of the ams. I have found pulling really really hard works but it feels like potential damage. Alternatively, remove tube at printer, pull out from extruder first and then it comes out with a firm pull…ie it is not rewinding but feeding.
