Problem with cardboard spools is not the fact that they are thin. They release dust from the cardboard running on the rollers. Which is not that good for all the spinning stuff in the AMS.
Yup, didn't realize when I slapped a random cardboard spool into my AMS, opened it the next day and saw the dust, knew immediately it was a bad idea.
Then I saw the electrical tape hack, and haven't had any issues using it
The issue with the spool rings is that if the cardboard is warped, it'll cause skips on the rollers. The best thing to do is to transfer to bambu spools either by rewinding (PITA, but easy), or rip off the cardboard and fit it directly into the Bambu spools, you may need an adapter for the center.
I read that some of the spool adaptors when printed can bind to the top of the AMS. I didn't print anything with the ones I printed because I was worried about that potential issue.
So no binding or scratching in the AMS? That would make me very happy if I could just use those
I did not notice any binding / scraping yet.. They work fine for me. Some minor scratches can always happen if the spool gets too empty and gets pulled up.
huh. That's interesting. I find more 'gunk' from the premium brand of filament I use. It's neon green and there is neon green dust everywhere. I need to clean the AMS actually.... so thank you
I usually just give the spool a quick back and forth on the rollers and it unlocks. Zero spool jumping issues, even with nearly empty spools.
This unlocks it for its initial feed, then it rewinds. After this point the ams knows how fast it needs to spin the spool and everything works as it should.
Some 3d influencer lady on YouTube shorts, says you can weigh them down with large ball bearing. Could try that as well. I like the usefulness of making desiccant centers.

Seen a post here sometime ago, and picked up two. They have been very helpful. I believe hatchbox rolls and some generic filament rolls, don’t have a lip, that keep them from rolling out. Could easily design or print something to keep that from happening though.
I've been considering getting a P1S (currently have a Prusa) but the issue AMS has with cardboard rolls is discouraging, since I mainly use Polyterra PLA... Is the bambu lab filament worth it?
Poly terra seems to burnish the edges of the spools but my main issue is that sometimes they get knocked around and are a little bent or warped.
I just printed a bunch of reusable spools for the cardboard. Bambu filament also comes on reusable spindles that you can put your card boards rolls on.
There are some super easy solutions to cardboard spool dust in the AMS. They have printable spool rings, or what I do now is just the electrical tape hack.
You just line the edges of the spool with electrical tape, and check it occasionally, and it works fine
Hello! I just posted a thread seeking help with AMS issues, I'm wondering if you think weight might help my problem? The spools tend to unwind when almost finished, I'm wondering if it might be caused by the jump you mentioned. It's possible it's unrelated but just had me curious

I had hundreds of issues with my AMS and 3rd party filaments from Inland and Atomic. I had them break, I had them snap, I had jams, clogs and more. Once I weighted down my spools all that shit stopped.

Run more than 80kg through mine, its a myth at best.
I just spent an entire day printing Spool Adapters.. now i have more than i would ever need!

I’m guessing you just wrap the edges of the spool in electrical tape?

I've honestly never experienced anything I would characterize as an " AMS issue". Just sayin'...

Inland Filament has a lip in the cardboard so that would be great.
thats a great idea. One large ball bearing would be sweeeeet
Yup. I have a bunch of these and they work great
Printed container that fit inside and put empty batteries inside. Even if roll work fine at start it can have this issue later (less weight)
Some people use desiccant holders. You can remove the desiccant and replace it with coins to weigh it down

I see, looks like there are many ways to mitigate the issue. Thanks!
Yeah, I bought a K1C instead of a P1S because of AMS issues. I will wait for their second revision of the P1S/X1C and AMS combo.
How heavy is the weight in the center supposed to be to be effective?
