I Accidentally Unrolled 1KG of PLA Filament with the Bambu Lab P2S… Here’s What Happened

If you’ve ever had filament explode into a giant rat’s nest, you know the pain. In this video, I accidentally unrolled nearly a full 1KG spool of filament while troubleshooting an AMS feed issue on my Bambu Lab P2S AMS Combo — and ended up with spaghetti all over my workshop floor. Instead of throwing it away, I spent 3–4 hours patiently re-spooling and salvaging nearly the entire roll. Here’s what I learned: • Why you should keep empty filament spools • How to re-spool tangled filament • When it’s worth saving vs. throwing away • Risks of bent filament in your extruder • How AMS handles partial spools and filament swaps Time is money — but so is material. Sometimes patience wins. If you’re running a 3D printing business or just printing at home, this might save you $15–$30 and a lot of frustration.
