Quick one here as it relates to all versions of the AMS, it’s printer independent. I’ve been able to reproduce this error with the last 10+ spools of refill and it’s happening regardless of the filament type. Does not impact the rear spool holder. Refill spool placed correctly on the notch, two halves seated properly. Load the filament and guaranteed that the filament will be pulled to the side of the spool and jam between the spool holder and the spool. This is super annoying when monitoring a print remotely with no way of fixing the issue. It’s gotten to the point that I only buy filament already on the spool to avoid this issue. Anyone else have this problem? Anyone have a solution that works? I have tried a few DIY solutions from Maker World already with limited success.
Can’t say I’ve had such bad luck, and have gone through 4 this past week.
The AMS should have nothing to do with the filament stuck between itself and the spool. I’ve had this on a few spools that worked themselves out as printinmg, and when I’ve messed up when twisting one half onto the other. Often if you don’t evenly get the spool half down before pressing and spinning you can get it trapped.
Have you done the “massage” to gently eliminate the side gaps once you click the spool together? I found the few refills I’ve used off BL are a bit looser than I am used to and see there is a few spacers popping up in Makerworld to counter this gap. I had one pull to the side before, I made sure the first pull is guided from the centre when I load up if that helps.
I am too. The refills are really cheap so I like getting the. Don’t want an office full of bambu spool frisbees. Was thinking about reapooling them to make tighter. But potentially loosing the RFID, which is pretty handy to have. For now I’m gonna try and manually tighten a new refill after it’s been put on.
I’ve had the same problem with the refills. In my case, at the edges of the spool the filament ‘dove’ down under other filament. As the unwinding filament gets to the edge of the spool the AMS is unable to feed any more. It has happened in 2 out of about 16 reload spools I’ve used. In my case I manually unwound and then rewound a couple layers from the spool. Bit of a pain, but it works.
Ive seen the same. Also seems like some of there suppliers make the refill wider than others. Some leave enough space on each side that the filament can fall into that space. Probably why some people have issues and others dont. Because they use specific filament from the better supplier. Either color or material.
I had this problem on a recent refill spool, where the filament dove under the space between the filament roll and the plastic spool. In the future, I will try unwinding and rewinding some filament to better center/reseat it.
Update - I have been advised that the trick with the BL refills is to press down hard on the filament after loading it on the new spool. The goal is to fill in any gaps between the filament roll and spool.
Now I have found a new issue on two of my red Bambu refills. Everything starts out fine, I load the refill onto a spool and install into AMS. Everything works fine.
The next morning I come down to find printing had stalled a couple of hours later. The cause, the filament was tangled within the spool. This isn’t the issue where loading a refill causes filament at the edges of the spool to be buried under other filament and get stuck, this was the filament passing under a bundle of about 10 strands of other filament. I had to remove the spool, completely unwind the spool by hand as there were multiple multiple multiple tangles within the spool.
When I was about to load another red refill, I loaded it normally onto a spool and then rewound it onto another spool. Again part-way into the spool I encountered twists in the filament, so I had to completely unwind by hand, and then rewind.
I think I’m going to stop buying refills,
I’m having this issue right now with mine. I just got my A1 and I ordered 4 rolls of refill pla and the one loaded at the back is getting pinched into the edge of the spool by the tension from the ams lite pulling the filament. I keep getting error messages and I have to go pull it out. Its really frustrating and I’ll have to stay up until my print finishes to keep an eye on it. I’ll try this massage thing on it tomorrow and se if it helps.
Just bought a lot of pla refill spools during the sale. First one i opened i did everything by the book when installing it but it is completly impossible to “massage” it since they have put some cind of glue on the filament, one side i was able to massage out but the other side of the spool it sems like the have coated the filament with something that glues it togheter so i cant make it fill out the gap on that side. very irritating and i sure hope not all spools are like this… Get stuck in the AMS al the time and very poor print quality as well so im almost suspecting that they have a lot of moisture or something in them aswell.
I bought a Bambu printer for the first time about 6 months ago. I had about 5 months worth of filament from my other printer. I used Overture stuff. about a month ago as i ran low and started buying bambu stuff, and now i am using it. And it cloggs NON STOP about 10 spools. all doing the same thing. i threw it all out, i cant be unjamming every printer ever 10 minutes, about $200 worth of filament in the trash and i will never use the Bambu stuff again, back to the overture for me.
So. I often have that issue with the AMS but no the AMS lite and only with refill spools. Was your filament getting pulled down the side of the spool and are you using refills ore filament already on the spools. Bambu filament is really high quality filament. It is unfortunate with the refill spools and the AMS.
Ive had it happen in both the AMS and AMS Lite. The issue is not the AMS, matter of a fact you can put it directly into any printed without AMS, tried it on 3 of my machines, it always gets stuck. You should not have to babysit a machine. I have gone through hundreds of spools of Overture PLA (mostly matte), with 500+ orders and over 25k in sales in my small 4 printer farm (3 fdm 1 SLA) and i can tell you factually that Bambu filament is ■■■■. Overture PLA is twice as good and is currently like $16/kg (black friday sale). If you dont like plastic spools you can print an adapter that makes it fit into the bambu reusable spools (or print those as well), and it will not jam.
