AMS filament roll lays on feeder and not the rolls - sticks!

[Silverbullit]

Each and every print I have to stand half an hour to an hour and turn the filament rolls by hand a few inches until the rolls no longer literally rests on the feeder instead of the supposed rolls… running like a hamster caught in a wheel to reset warning messages on PC and retry/resume the prints… (It is hurting the prints also since it often misses some lines at the restarts)

I’ve done this since January with more than half of the rolls, I just stand there and google useless ■■■■ on my cellphone… but I’ve had it.

I googled this waiting for an obvious hack to fix this, as I figured it was the same for everyone… however now since a few months I have 2 bambu printers with am-asses and obviously both does the same… and now I stand there like a dummy with a hand in each AMS looking out the livingroom window - people outside look back thinking I’m a Zombie or sumthin…

How did you solve this mates?

Is it the hydrophone mod that fixes this?

In dire need of your help mates!
(On otherwise such genius printers I really dunno

What brand of filament you are using?
Hydramod could be an option or respool the filament.

Yo mate,

Well kinda an unholy mix… very new to 3D printing
right now looks sumthin like this,

well my humble setup more precisely,

Mostly use, eSun, Stronghold, R3D, Azure, Prima Creator, Fiberlogy, Add North, Sunlu, Bambu basic, 123-3D, 3DJake, Fillamentum asf also have a literal stack off a few each of those brands supposed to be better. (I wont mention the odd horrorshows like 3DFils - save a dollar/roll and buy replacement parts for 200dollars for every second roll… )

A fair judgement… sumbeach around 60% needs me to manually unroll the first half inch of thread, particularly in the newer like 2-3 months old x1cc that gets electric motor overload if I open the lid to the AMS and it thinks its dinnertime… but a LOT of rolls.

Looking for a solution here to preserve what shrapnils of sanity I still stumble around with here

I use the spools from Bambu Lab, eSun, Sunlu and Elegoo and non of them gives me any problem. I also use spools from 123-3D, the Juniper series. I can tell you the old spools wont fit in the AMS, but they have changed the spools from the Juniper series with 1.1 kg filament on it. They fit as they are smaller.

You can check the AMS compability from this sheet.

I have this issue with more or less each and every brand, it is just a gamble how nicely the rolls are winded up…

These things, depicted in link, stick straight in to the filament in the rolls. Yes in to the very space where the filament is supposed to occupy;

AMS First Stage Feeder

Since the rolls sticks in to the filament on the roll the rolls cannot seat properly and the first stage feeder bites in to the filament and the rolls cannot move, they are locked up. When patiently moving the rolls an inch at a time by power of your own hands it will gradually prone to stick less along with the filament being unwounded giving the first stage feeder free space. It mostly only takes 30-60 mins but it gets tedious when it is something that should not be an issue.

It is quite self evident that the first stage feeders should not stick inside the radius of the roll. And anything of that sort is a no brainer…

Undesputably a design flaw

Which is really surprising, almost everything around BambuLabs X1CC printers are amazingly well designed. I gather that software development will always carry bugs between versions (Right now I have a lot of issues I never seen before with PetG that clearly is due to latest firmware/studio since both printers started exhibiting same failures at the same time. Nose build ups, heat bed warning messages, suddenly I have feeder failures on both even after changing E V E R Y T H I N G with the spare parts I stock for brand news and both subscribe to perfectly the same failures to withdraw filament asf Come on, both at the same time, yeah firmware for sure.)
But as far as hardware goes it is really surprising how tight and great these things work and hold up. Got no#1 back in Jan/Feb’ish? I dunno exact mileage but I presume a couple of thousand hrs and prints like a champ!

So how could they miss seing with the naked eye that the first stage feeders poke straight in to the center of the filament rolls that can only fit if they have an inch of clearance and are not full rolls?!? Great minds missing something so obvious? I’m actually quite curious what happened here and what the great engineers have to share about what happened here?

But nope, all brands does this, and do so in both AMS’s
(New one is much worse since it complains the motors are overstrained even on rolls that I cant feel have little or any resistance at all. So it triples up on the need of rolling each and every roll by hand…)

Do you not have this issue at all mate? You seem to roll with the same rolls I do so I am quite flabbergasted on this side of the screen right now

Have you done the Hydra-mod and if so did it solve this issue or did you never experience it at all from start?

Look very much forward to your replies here

[Avgils]

No I did not do the Hydra-mod and I don’t have this issue at all. Everything works smove as it should be. I had some problems with slot 3 at the beginning, failed to unload, but after removing the Y-splitter and change the AMS-buffer for the AMS-HUB that problem is for 99% over. During the troubleshooting I completely disassembled and cleaned the AMS and find a piece of plastic in the internal AMS-HUB that didn’t belong there.

[Silverbullit]

Still have not solved this, every fifth roll is too full and hangs on the first stage feeder.
Is there some solution for this, like raiser rollers freeing it up from hanging on the first stage feeders that literally sticks in to the space of the rolls so that they have to be unrolled a centimeter or two… (half an inch or more)…

Thanks mates for any advice or help in solving this…

(I been up and pressed “retry”, a couple of times for each percent of the print, doing the unroll roll up whatever it cranked out inside the ams, every time it stopped and flagged “ams motor overheated”… after some 300 messages it starts getting annoying! Also doesnt help to have insomnia. Should I just ripp off a fourth of the badly rolled up filament rolls and dump it in the garbage? Im not greedy, I’m poor, so that would feel like crepe. But been doing the handfeeding like an absolute muppet since I got my x1cc’s basically at Bambus startup.)

To clarify, I absolutely love my X1CC’s and gotten totally bambuholic due to them

But it would be a biggie for me if somebody could dumb it down and give me some pointers here…

(I tried printing out a couple of versions of filament re-rollers, however they sucked so much that they made the rolls even worse after intense fiddling. Pherhaps theres better solutions out now? Its been almost half a year since I gave up on those buggers.)

May the force be with you mates,
