I have also had tape get stuck in the AMS feeder funnels, from spools bought just a couple weeks ago. I submitted a ticket with pictures and I think their response is pretty insulting. They talk about the old taping method vs the new taping method and offer to replace filament if you can prove it’s the old method. They won’t even consider that the new taping method isn’t working either.
As others have already stated, the risk of damaging equipment over a piece of tape, and the defeat of the auto refill feature of the AMS, and the way they have handled this, are appalling, and a class action lawsuit is definitely in order.
Here’s is my first Bambu spool that ran out. I ordered this on 9 Dec 2024. It appears as if they are still using the tape, but it appears to have been applied correctly in that it released the filament without pulling the tape along with it. This does not appear to be a different kind of tape from that in the other photographs. Perhaps their application method changed, or I got lucky?
I guess take two.
2nd spool from the same order, but this time I was ready.
Yeah, BL really screwed the pooch and the funny thing is they act like they have no clue (reply to support ticket as if this is the 1st time they hear about it)
It happened to me today with a newly bought White PLA Basic. The “correct” tape is still causing issues, I was ready to see what will happen and sure enough the tape got ripped from the cardboard, so I caught it before it got sucked in.
I hope you put a ticket in to tell them about this.
As we know by this thread, people are still getting spools that have the old tape method and Bambu Lab is not bothered by this. If they did decide to not use tape any more, then how long do you think it would take for all the taped spools that they have in stock, to go? They are not going to respool them but just sent them out to their customers.
I got my first 3D printer this past holiday season and every bambu spool I have used has been taped and the tape ripped off and almost caused a problem. It is good that this thread exists so I know how it is suppose to work. I will open a ticket as well.
They won’t decide not to use this crappy tape. See Tape at the end of spool - #87 by SupportAssistant if you didn’t already. This is beyond idiotic.
I know where to spent my money now and it is not on BL spools.
The tape that I found on my recently purchased roll is so small it would have no chance of releasing the filament. The issue seems to be progressing in the wrong direction. PLA Basic Black
Welcome to the forum.
Please put a ticket in about this.
Bambu Lab may offer you a “1 time replacement” where they will replace the 1 spool that has a defective tape issue with a new spool (which also may have a defective tape issue).
Then any other spools that you have the tape issues with, they will just laugh at you and thank you for your money.
I have 15 refill spools coming in. Half of them is here already.
Today I emptied the first one, PLA Basic Yade white.
It was meant to be an Auto Refill print, the built plate was full.
The result: a not finished job because it got stuck. At least the AMS pushed it back out but then got an error because it couldn’t pull it back with the spool roll motors.
Can we invoice somebody for rewinding the spools?
I had an issue with the tape coming off as well, luckily AMS lite detected an issue and didn’t pull the tape in. Had quite a few of these more or less small issues with the A1 + AMS lite / the filament. It’s not as “just works” as it’s made out to be. Still great machine, but it feels like quite a few normal use cases have not been considered thoroughly enough or quality control is just not up to par.
Glad someone is trying to solve the problem by cutting off the filament so it can run out like normal. I tried to figure out a method to do this very thing, but I just couldn’t think of a way to design something that would fit in that space. Going to have to give this one a shot.
I will try to have a constructive look at what I see, what I read and my own experience.
I noticed the change made by Bambu lab on the hook of the filament. I confess that it reinforced the idea of ready-to-watch the end of the reels.
That’s why it is not a good idea to attach a filament with adhesive. It does not stand to be heated (yet necessary for drying). The migration of glue can be fixed on the wire, which itself is deposited in the PTFE, in the sensors (hub and extruder), come to plug our nozzles.
We have to find a solution on the end of the cardboard without making an end angle too violent. Or a solution would be a weakness on the attached filament that would come to cut. For example, a decrease in diameter.
From my experience, when it is the end of a reel, I launch an impression to pull the thread to the end. But when I got to the glued paper, I unroll the reel and cut right in front. I would try to create a weakness without cutting the filament soon and I would try to show how I do it. But let’s find a solution together.
And 3rd spool of ABS: same exact story. I guess I am that lucky or a lot of them are like this.
I have only one more ABS and two PLA spools from BL and hopefully I get rid of this issue and BL spools.
This continues to be an issue as of 1/10/25. I stopped using Bambu Lab filament a couple months ago because of this issue. Just purchased some more Bambu Lab filament because I thought they had fixed the issue…NOPE. This is causing failed prints for me and costing me money and time. This is ridiculous that they refuse to fix this issue. I have spent thousands of dollars on their printers and parts. They can make these great printers but can’t master something simple like putting filament on a spool. They need to either take it off or use longer tape so that it can’t be pulled off so easily from the carboard spool.
The first post in this thread was May 2023.
They are still having problems with tape now.
Besides the tape being ripped off and damaging the First Stage Feeders, I don’t think anyone has properly looked into what affect heating the tape up while drying the filament will do to the adhesive on the tape and how much will be left on the filament and pulled through your AMS and printer, leaving adhesive in it’s path.
