25kg spools
2 ways to maybe help with the filament coming off the edges of the spool. 1. Add a cardboard barrier to the spool to give it a much higher lip. 2. Lay a towel on top of the filament spool so that it drags across the inside of the spool weighing down the filament but not impeding rotation. Some industrial machines use plastic flaps or the like.

yea i know.. 25kg spools, i've gone through 1 in about 2 1/2 months, have 2 more 25kg spools a 15kg and a 10kg.... that doesn't even include all of the little 1kg ones i have. lol
thats kind of what i figured. Right now i have a trash can with some foam packaging sticking out shoved under the spool and its working.
I'll probly end up printing some sort of contraption to mount to the spool holder that will allow adjustable tensioning since i have some 10 and 15kg spools as well.

I don't know if it will fit a 25kg spool, but maybe it can be scaled up.

actually i printed something like that originally but the weight of the spool proved to be to much for the extruder to roll the spool on the holder (it was support by 8 ball bearings and 3D printed parts). Currently i have 2 cups that slide over a 3/4" aluminum tube that makes the aluminum tube fit the spool holes nicely, the tube then has machined ends to adapt skateboard ball bearings to it, then it rests in a combination of G10 plate and 3D printed holders hung off the side of the machine. Its kind of crude, but works amazingly well (to well really.. lol). I'll have to post photo's of this monstrosity later on.

I don't have massive spools, but I also use a bearing hub to keep them rolling smoothly, and I had the same problem of over rotation and the filament coming off the edges and getting tangled. I added a reverse bowden tube that went from a block fixed to the printer frame and then to the extruder, but it wasn't actually attached to the extruder. This allowed a fair amount of filament to be unspooled into the PTFE tube and added a bit of friction as well.
There might be a picture of what I mean in the link in my signature.

i have a setup like that to! lol. Its dangling though and i have thought about moving the spool up the printer frame so the bowden tube actually hangs below the spool Centerline hoping that will straighten things out. My trashcan is working pretty well right now though. haha
