I’m having issues with the AMS where it seems like the filament retraction is faster than the spool rewinds and the filament gets all tangled inside the AMS. This happens on both Overture cardboard spools with printed “rims” as well as Bambu spools. I’m 99% sure this is due to the light weight of the spool as it is used but would like to know what the best solutions are.
Does the Hydra improve this retraction issue at all? I’ll probably do the upgrade anyway but would like opinions on with guides vs non guides Hydra versions too.
Do these Silica Gel spool holders provide enough weight when filled with desiccant to help or alleviate this issue?
I think I’ll switch filament suppliers when my beloved Overture runs out due to the cardboard spools. Would love recommendations for PETG filament available from Amazon that works great with the AMS.

From my research the non guides are better if you use rolls like Atomic filament so the filament will not hang up on the guides or mods some bigger rollers up with the lid spacers also might work.

I put a C battery in mine and it has been working for me with my plastic rolls but you can add nuts or bolts. The ones I used are like the ones you linked.

For the record about half of the Overture spools I’ve tried work perfectly fine in the AMS but the other half only mostly work regardless of the type of rims I put on them. In my case it seems the bad cardboard spools are quite a ways out of square. I’ve never had an issue on feeding with these bad spools, only retracting. They are easy enough to respool onto Bambu spools so I’ve taken that route for now.
I do have the same issue with all spools when they get down below about 1/4 full though. For that I think I need to add weight.
Ya the weight has helped with the low spools I have one roll about 1/8 and it’s still working when unloading at this time with the C battery load test lol.
adding weight does help, i made some silica spool center so they are larger and hold more than ones i seen on line… cardboard spools don’t work well they slip, weight can help, best to either get plastic spools or transfer to a bamboo spool… also make sure it sits in the AMS correctly, if not all the way to left and can also cause a winding issue since wider spools will drag. i had a few issue back when i got the first printer.
my go to filament is CC3D and NOVAMAKER and the prices are very good as well, haven’t got a bad spool yet like some others and i used hundreds of spools from each… i used PLA, PLA MAX, PLA SILK,ABS, TPU, PETG from them and never any issue always good clean prints. if you need the silica spools let me know i can post them up for you
Just an update on this from my end. I tried one of the silica spool inserts filled with silica beads but it only made a small improvement. I then exchanged that for 2x “C” size batteries and it completely solved my problems. It went through 109 filament changes without fail after that.
Big thanks for the CC3D and NOVAMAKER recommendation. They’re even cheaper than the Overture I’ve been using and come on plastic spools. I ordered one to try out.
I have the same issue and I only use Bambu lab filament. I’ve had the issue even with full spools. It starts to rattle and the filament will start getting tangled because it’s being pushed back in but the spool isn’t moving. It only happens in slot 3. Sometime if I move the spool around it will start to move itself
When I first got my printer I was having that issue on slot one and I noticed there are two different places you can stick the roll one spot it has issues but move the roll over a little and it doesn’t.
