Agree. I am totally pissed because of this crap. Makes AMS more or less worthless.

Same here. Brand new P1S+AMS and have this issue after every print.

@@Haapavuosame here not even two weeks old

@@Haapavuo same, P1S Combo having this issue after 1 month of use... the slot #3 (from left to right) is the worst.

​@@JEYMSyup. Exactly. This N3 is a nightmare... I thought I had a defective AND, but it looks like it's a bad design. Any be some clever guys will come up with a solution. If any of you find one pls reply.

Happy this helped you! follow me on IG I have more tips and fun stuff on going on there.

You are more capable than you give yourself credit for. It is 2 screws and a T shaped push button on the inside back of the AMS where the tube goes in. pushing that allows you to pull the tube out, making removal fairly simple. just watch the 2 wires as you lift the internals out.(also easy to disconnect/reconnect). Scary on your new expensive equipment? yes. hard? no.

Correct realized that a bit later that retry would just retract it back.

Since then I have gotten the message a couple of times. There a new easier way. Just disconnect from the back. But you don't need to pull it out. Just hit resume on the screen and it should unwind. Once the filament is out of the extruder portion and just hanging out.

@@3ddiy thank you!

@@3ddiythank you ❤❤❤❤

I came here because mid print I got the error hit retry and it continued with the print, but the error was still stuck on screen the whole time with no way of getting rid of it.

@@lazydog6642 good luck with Bambu customer service. Can hardly use my printer since I unboxed it. Asked for an exchange because this is ridiculous, but they won't do it because I didn't turn the printer in during the first 14 days (I spent these 14 days waiting for answers from their customer service btw). I'd never buy from them again, in case you get one of the few buggy machines and don't have a ton of followers on social media you're screwed.

This issue honestly hasn’t happened again to me since I posted that reel. Love the machine. I actually think it’s priced pretty damn well compared to what else is out there.

​@@3ddiyhow is it going now? Is N3 vaving faults anymore?

Nope hasn’t happened at all since. I did print the little anti bend elbow.

Since I made this video I have learned that right above the extruder the PTFE tubes bends a bit too much. If you print this model it should help with it. I never had the issue come up again. makerworld.com/en/models/165609?from=search#profileId-181838

Alrighty! I'll print it now, thank you so much

sorry to hear you are having an issue. What is the problem? have you tried going on the forums? or reddit r/3dprinting to see if anyone can help? It may be quicker than support. There are a lot of users out there now. The Bambu is a small company but they have grown really quickly. so I'm not surprised that support might be slow. but there are a lot of resources on there and things are well documented. But reply here maybe I know and can help.

Deal! Also since then I found out if you just pull it out of the nozzle you can hit retry on the screen and will just retract it for you

Glad that works for you but it doesnt for me. My friend swore by the "wiggling" method and said I must be doing it wrong. He came over and tried it himself and it didnt work. My newest P1S is 3 days old and is already getting stuck. Lid riser, every version of shortstack thing, longer and shorter ptfe, cooler bed temps, etc....Nothing works

@@OhImKiCkiN I mean that sucks…and my guess is that yours is getting stuck in a different place…how do you fix your problem then ?? Where does it seem to be stuck ??

@@stevekay6895 It's getting stuck in the print head. The filament cutter cuts it but it won't retract randomly. I have this issue on all my BL machines except 2 of them. This issue was kinda rare until 2 updates ago. I really think BL changed something. Maybe they reduced the voltage to the ams motors? Idk but I constantly have to run from machine to machine and pop the Bowden tube loose behind the machines where it comes from the ams hub into the machine. Then I pull the filament with ease like 2mm and hit retry and BAM it retracts fine. BL support runs me in circles. I've sent countless videos, log files, and multiple tickets but they won't even offer to send a motor or anything. I love BL but their support sucks. You'd think after giving them $25k+ they'd offer a little help.

@@OhImKiCkiN That’s exactly what I’ve been getting as well only the “wiggle” does work for me. I had the most trouble with MicroCenter filament that was sparking and clear. Slot 4 also seemed to be a particularly bad slot for a while but I’ve honestly had the opposite experience since updating. Have you tested various materials and temps as well ?? I think I narrowed my problem down to the filament with isolation. Hope you get it sorted tho 👍

@@stevekay6895 Thanks for the ideas. Yes I've tried every type of filament on hand. PETG never gets stuck in any machine, I'm guessing because it's so slick. But PA, ABS, ASA, PLA ,PLA marble all get stuck randomly. I've tried Bambu, Sunlu, Esun, Stronghero, Colido, Kingroon, Jayo, Flashforge, and Overture PLA and they all randomly stick. I even tried putting weights inside the spools but it didn't help. Also it's odd that you mention slot 4 being worse because on some of my units slot 4 is worse but most slot 3 is the worst. Rarely ever do the 1st two slots have an issue.

So people believe the issue is from the sharp bend of the tube at the top of the extruder assembly. So people have made a model that keeps the tube more rounded and less of a turn. But I can’t seem to find the design right now. But I haven’t had the issue pop up. Since I used a different brand filament. For me it always happened with this one roll not matter which ams slot I had it in.

Found it www.printables.com/model/309088-bambu-lab-x1-ptfe-minimum-radius-guide

Print and install this on top of your extruder. Also there are some particular brand of filament rolls that don’t work well with the ams. makerworld.com/models/62214

@3ddiy appreciate the reply. Everything is bambu brand. Everyone keeps saying replacing the ptfe fixed it?? One guy explained it exactly what is happening to me. Goes all the way to extruder gears. Sits for 3 seconds then returns to ams , rinse repeat 5 timed then error

​@@ChrisHensley2 its possible there is a jam in the extruder. A piece of filament is lodged in there. I would follow the steps from bambu on dissassembling part of it. Or use the induced needle to push up from the nozzle side. See if you feel any obstruction. or if you can free it up. As said in my last reply I have also had the same issue with particular third party rolls that the ams just didn't like to pull and retract. But I think that may be a different issue now that you describe the pushing and sitting for 3 seconds.

@3ddiy I took the whole assembly apart. I promise there is nothing there. I played with the extruder with it all taken apart. My theory is that the tension screw is way too tight, but bambu in their infinite wisdom does not provide clearance when that screw is loosened. It takes a fair, hefty push to get through the gears and feel tight. I loosen the screw, it is smooth and if I turn the gear, the filament moves. However, this is not helpful because I am forced to tighten the screw again to put it all back together. I don't know if I am crazy at this point 🤪

@@ChrisHensley2 if nothing is in the extruder then it’s the ams or the bend on top of the extruder. Have you tried taking the ams out of the equation and just run it with the spool on the spool holder on the back of the machine?

you have to push in on the lock(ring around the tube on the connector) helps if you push the tube in alittle as well. then it should release and you should be able to pull the tube out. If not you can try to go above the extruder. Try to straighten the bend with your fingers or lift up the lid and hit retry. That is where it's pinching and needs to release tension or pull it out.

There’s a plastic piece on the female end you have to push down and then pull the tube

@@3ddiy wow yup, found it thanks!

@@megananimirkhanian8215 once you get it out the extruder on the screen you can hit continue and it should pull it back instead of you do it automatically

@@3ddiy perfect, got it working, appreciate the help!

I keep getting this on slot 1 and 3

It shouldn't happen mid print unless you are doing color changes. but yes you can continue where you left off.

@@3ddiy Holly that's awesome in case filament issue while printing, sometimes filament are not well wind

This is because right when it ends it's trying to retract the filament all the way. People believe the issue is the hard bed right above the extruder and have designed a more rounded elbow attachment that you can print and attach. So it makes it a bit smoother for the filament to be pulled out.

@@3ddiy That mod helps by reducing this occurance but it still happens often enough to be a major problem for me.

Sorry you didn’t find it useful. But since this short it’s actually easier process. You just need to remove it out of the hot end to clear the kink on the top. Then on the screen hit resume or okay and it should just reel it all back on its own.

@@3ddiy please don't be mad at me. there are just too many ways the filament could be stuck. in my latest case I had to completely disassemble the extruder to get the filament out of it. but even in your case you completely skipped the details. hmm... maybe that's a reason why I don't like shorts in general 🤔

@@therealchris no worries. So this error here happens at the end of a print. when it's all done. It's a fairly common problem with Bambu users. The error message has to match what I shown. it's when the filament gets pulled back up into the AMS. When you hit retry it just get stuck. But the filament is usually already out of the hot end and just stuck up in the bend. What you had sounds like a different issue. Sounds like you found the right resource and fixed it. My buddy Lukeinthegarage had what he thought was a jammed nozzle but it turned out to be a bad extruder board. So there are the rare instances where it's not what I mentioned.

There is a black ring where the tube is inserted. That needs to push down into the connection and the tube can then be released and pulled out

@@3ddiy Hey, thanks! In the end, I managed to fix it, but I had to disassemble all the tubes starting with the one that connects the AMS to the hub because the filament got stuck in the hub and was very tight, not coming out through any other connection. I used cheap Chinese PETG filament without drying it, and it worked well until it was almost used up.

@@Increibleperocierto123 ​​⁠I had to do that once. Yea, it’s not fun. But easier to do again that you know how to do it.

You okay? Well there was an error as it showed on the screen, And actually a fairly common one that is from the pinched Bowden tube above the extruder. Since making this almost two year old short. I have many comments below where I replied on how to fix the issue more efficiently and how to remedy it with a 3d printed part that stops it from happening. You may have seen this short recently because the algorithm sent you here. But this issue was pretty early on when the x1c's came out and everyone was figuring things out. But hey! you are free to comment anything you want. It actually gives me engagement. So thanks for that. Sorry you won't be subscribing. But it's okay I'm pretty happy with the 2K+ followers I have here and the 85K followers I have on IG. Much more supportive comments there. You keep on being classy. Hope you have a great rest of your week bud.

Yep, figured that out a week later.

There is a flaw in the design of the printer. The PTFE tube on top of the hot end bends too much causing the filament to be pinched and difficult to pull out. People have designed guides to lessen the bend. I have found that I only have this issue with certain rolls of filament oddly enough. www.printables.com/model/350714-bambu-lab-ptfe-guide
