I haven’t printed or tried any respoolers (yet) so can’t really help with that.
And on filament the only other brand I’ve used is Hatchbox and it has been fine. I have some Elgoo in the dryer right now but have yet to print with it. So not much help there, either.
Sorry about that.
Follow up on dealing with Bambu Support on this. They will do a one time replacement of all spools you can prove you had issues with. You have to get a picture of all the spools, so don’t throw your old spools away. I am going to save some up, why not, lol. Right Now I only have 2 spools that had issues as they go in the trash as soon as they come off the printer. But now I am going to save all the bad spools.
Again, to anyone having the issue, please put in a ticket with support. The only way they will ever fix this for good is if they keep having to give product away or refunds.
Please can you ask them why it’s only an ‘one time replacement’ when they are constantly sending out spools which have the issue.
Surely they should replace all defective spools.
I also did that, and got 3 spools that i was able to prove (pictures, video). However, i have 7 left unopened. They said to me the same: it’s a one time gesture. And i was planning to get a few more. Please make sure to have a picture of the box, as it has a serial number that they need in order to track the bad batches.
However, to be fair, i did use the filament, so i can understand the fact that they won’t just want to refund every single roll that i use. I just hope that they fix it ASAP. I will still send them tickets if they still get stuck, in hope that they’ll be able to find the errors address them.
Thank you. I’m new to 3D printing and was wondering how the filament change worked when I saw at the end of my first role of PLA - matte the end was taped to the cardboard cylinder. It was that black very sticky material tape, so in no way was it going to release. Thankfully I was there monitoring it.
Here we are over a year later and all my PETG HF Refills are using tape and getting Jammed in my AMS?
Bambu Labs, you have been asked already to stop doing this. Please listen to your customers.
I found an older Reddit post where someone posted having tape at the end of a refill getting stuck in there AMS. A reply mentioned that it most of been from an older batch.
Just curious if anyone has any information on this? Did they change the manufacturing process? I just recently purchased a huge lot of refills of PETG HF (which is fairly new filament as I only have seen the ads in the past month ) and so far all 4 used rolls use tape - all of them have gotten stuck at the insert point luckily and just pause my prints.
EDIT: - Just found this post with MAY 2023 date - really?!?
I dont believe they stopped using tape, I think they changed the process slightly hoping it would start working as they hoped (tape stays on the spool and the filament pulls loose). Unfortunately by the number of complaints that pop up it’s still a problem.
I just shake my head at the way this company operates lately. I opened up a support ticket. I don’t think it’ll go anywhere thought — just hoping we get that one rational support rep that forwards it onto the supervisor that takes action.
Yep. As far as I can tell there are at least three iterations of the tape method. The first was just tape the filament to the hub with black tape crossways to the pull direction with the full width of the tape holding onto the filament. That seemed to always pull the tape into the AMS and/or extruder.
They neatened it up and oriented the black tape with the long axis oriented to the pull direction and just a 1/4” or so of filament under the tape which worked better but still had casualties.
There was also a post with a photo of white tape in the newer orientation but IIRC, that also ended up with examples where tape got pulled in. Don’t know if it was the same as the black tape except white, or a different tape altogether though.
They seem to be trying but all the spools I’m hitting now are taped. I finished off some old stock recently that used the hole, but everything I’ve seen that was bought since last spring has tape.
Another issue with the tape someone else posted about and I bet they are right is when drying filament, the heat “sets” the tape adhesive where it may grab the filament even harder and make it more likely to pull it into the extruder/AMS feed mechanism. I’d bet when they were testing they didn’t run through a heat cycle to simulate drying before their test pulls.
This tape issue basically thwarts a bullet point on why the AMS is so handy. They have made automatic failover from empty spool to a full replacement a great opportunity to gunk up the AMS. I tried it back before tape and it worked great. No way I’d risk it now.
So so bad. Perfect printer. Why the tape to jack up the AMs?
Got caught by this today, too. The black tape at the end of the filament got badly stuck in the feeding funnel of the AMS and it could not automatically continue with another slot which had the same filament loaded.
Very annoying …
I got a roll the other day that still had the old system haha. Guess light grey did not sold as much?
I literally opened a support ticket with Bambu today regarding this exact problem. They’ve done this on every spool I’ve had, and out of the 6 that I’ve used, only one has successful stayed on the spool and swapped to the next filament (if using the same filament x2).
I’ll let you guys know what Bambu say, but considering this has been going on a while, I don’t hold out much hope. 
You will probably get the same ‘one time replacement’ rubbish that they have given others.
It’s a shame that they know they are giving out defective spools but will only sort out their problem once…
It’s like they are sticking two fingers up at you for all future defective spools that they send you…
Below is Bambu’s response on the matter:
Obviously I’ve fired back linking this thread, thus proving it’s not a “very small batch.” Additionally, as people have noted previously, this is occuring on a multitude of colours, not just (in my case) black.
My full response below:
Submitted ticket for this last week when i caught 2 rolls that were going to pull tape free and one that had pulled the tape off and started to enter my AMS.
They offered literally nothing.
I’m not going to buy any more refill spools from Bambu til this gets resolved. This is not a “small batch” issue. Fix your ■■■■ and purge your garbage inventory. I’m buying Polymaker til you guys get your act together.
I’m still seeing this issue and I would love for @BambuLab to address this. We all buy the AMS for the added convenience and efficiency, and this completely undermines it.
Dealing with a recent project where a part goes into 14h+ prints we usually prefer to leave it printing over night with AMS backup on.
We’ve had this issue so many times now that it is becoming frustrating and uterly infuriating to come the 2nd day at the office and discover the print paused with AMS stuck with the tape inside or the gear motor stalled not able to get the last bit of the filament released from the tape.
Some options I would see being implemented to address this:
Either of those 2 would imidiatelly adress the issue via a SW update, till Bambu reviews and addresses their spool manufacturing, which is clearly the main culprit over here.
