Poorly wound filament

this happens to me 1 out of every 10 rolls or so for a while but now its so frequent i switched to polymaker for filament

A year on from the OP and Iā€™ve been having issues with my standard gray PLA spool (not a refill) jamming part way through long prints. Iā€™m about half way through the reel now and the problem appears that the filament is threaded under the next layer, so locks itself. Pulling the filament out and back through the jam, and then reinserting sorts it out, but it means that the print is stalled for a few hours overnight whilst unattended and there is that tell tale line.

Is there a way to prep to minimise this happening? So far it is only the gray Iā€™ve had an issue with, but at less than 100 print and only two colours used (black and gray) I havenā€™t a super wide expeience yet.

Other than completely rewinding a spool yourself (i.e.: manually transferring the filament from the original spool to a new spool), I canā€™t think of anything that can be done to guarantee there wonā€™t be any tangles present. If you have a long unattended print planned and you canā€™t trust a spool of filament, then the hassles of rewinding may be worth it.

March 2025 and sadly this has been my experience also. Bought 5 refills of PLA and everyone of them has been terribly wound. Jam after jam and ruined prints. Very disappointed.

I am having the exact same problem you are. I opened a ticket for it.

This information sure is in the instructions, point 4 in the instruction

I tend to rewind all refills, I do mot use bambu filament so I do not have to worry about the RF id. With a printed rewinder it only takes about 2 minutes to rewind it.

Iā€™m still finding this issue in 2025! It is hit or miss whether the spools from BL are wound properly. I find myself having to respool them myself.

Same issue here in 2026. For the past 6 months everything has been fine using mostly exclusively BL filament.

In the past month Iā€™ve had 3 tangles - all from BL factory spools. Luckily only once per reel but annoying nonetheless. Good job the printer informs me of the tangle without too much force causing issues and I can simply untangle it a couple of feet and rewind tightly. Then everything proceeds normally.

Yesterday however was even worse with a brand new refill - after placing into a BL reel and putting it in the AMS got immediate tangles as if it had been wound off to one side.

Double and triple checked and yes, I had put it in correctly (e.g. lining up notch etc) so couldnā€™t understand how it was so poor from factory. All my other refills past few months have been fine.

It was so bad I had to use my pasta-lite to rewind onto a donor spool and then re rewind back onto the BL spool. Iā€™m shocked at how badly wound it was - my 8yo couldā€™ve done a better job.

Still at least I could put the pasta lite to use which worked brilliantlyā€¦.i now have a nice tightly packed filament back in use.

I pretty much only use BL filament but these issues make me a bit waryā€¦.
