Filamentalist passive filament buffer test & initial start

[@ogpennywise]

Nice. I was going to ask how you tuned the filamentalist, but I see you have the same issue I'm having; excessive looping.

I had the same problem; basically there's too much friction in the one-way bearing. If you turn the bearing on the axle in the right direction, it should run very lightly, similar to the 608 bearings. With too much friction, the filament feeding out will cause the spool holder to turn the spool, faster than the filament is being pulled out. The document included with the Filamentalist files doesn't explain how to fine-tune this, but there's a page on the GitHub archive that does: 1) Heat the one-way bearing on the axle, using a heat gun or blow dryer. When warmed up, turn the bearing in the free direction a for a bit. This will loosen its internal springs (be careful about overheating it) 2) Apply a mall amount of silicone grease to the bearing. 3) Use an axle with slightly smaller diameter, or turn/file down the center part. My bearings ran noticably lighter after the heating trick, and I also turned down the axles by 0.2mm (they were slightly oversized). That did the trick, and the spool holder correctly winds and unwinds the filaments. If you still get looping, you can add an adjustable screw with a felt tip to press against the roller and provide a small amount of friction. BTW I also found that the thing works just fine without adding (unobtainium) rubber bands to the rollers, but YMMV with very light spools.

Can I install this on creality k1?

I don’t know but I think you should be able to.

Voron ercf vs bambulab multicolor prints video?:))

Not a bad idea.
