Has anyone else had issues, lately with some filament refills being really poorly wrapped on the spool? I’ve noticed, mainly with PLA Basic, that rather than being neatly rolled in layers, it looks like a tangled fishing reel. I’ve had several prints, some long running, stop and sit for hours because the filament gets stuck. This doesn’t just happen on a brand new spool, either, I’ve seen it occur halfway through.
Welcome to the forum!
Yeah, it’s a problem that’s been reported a few times over the years.
I had that recently too. As well as the poorly cut cardboard centre.
In most cases, a good “massage” of the assembled spool in combination with the AMS savers saw me through though.
It seems this is not limited to PLA, my PETG-HF refills have been really bad recently. I had a 8 hour print turn to garbage because the AMS hit a tangle in the spool and did not print for 3 hours. When I fixed the issue and resumed the print, the filament did not bond well to the layer that was sitting for 3 hours and I ended up having to scrap the whole print.
I think Bambu needs to check in with whomever is manufacturing your spools as they appear to have some quality control concerns.
Yes, it is a refill rather than a material problem.
But using AMS savers from MakerWorld, Centre Spool dessiccant holders and being careful when closing the spool while remembering to massage the refill can really minimize these entanglements.
A shame that they still use that tape at the end of the spools though…

I just printed out a set of the AMS Savers myself and are giving them a try. I needed to do the Steel Wool cleaning trick to my build plate as I was having some issues with prints sticking to the plate. But I am all good now and will be setting up a long print today with a fresh PTEG-HF refill with the AMS Savers, so lets see what happens.
Thanks for the tip, I will massage the refill a bit as well.
