i am in the middle of a meeting watching this video and when you failed to mount all the rewinders, I just couldn't explode on laughing, because it reminded to me, it will appen when I'll print it, and that's impossible to avoid. Nice work mate
Tried this out. Had a couple of issues. On a heavy (full) carboard spool, it can barely turn when it reaches the end of the spring. Too much friction. On a light plastic spool (almost empty), there is not enough traction and it just slides and barely activates the spring at all. It's a pity, as it would be nice to have something much simpler than the RepWinder that is RepRack and RepBox compatible.
There's a certain point at which the inner coils build up enough tension and the spools begin to slide over the surface of the cylinders. You can actually see this happen a little bit in the video about 15 seconds in. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ic9dLWOwyYM.html I actually wondered this exact same thing when I first printed a version of Vincent Groenhuis Auto rewinder for my Prusa's MMU2s setup and was really amazed how well it acted once the cylinders stopped. Here's one of his versions: www.printables.com/model/168-universal-auto-rewind-spool-holder-mm
@@moshe778950101 correct it follows the same idea as Repkord's Slip Cover www.printables.com/model/135700-slip-rod-cover-for-reprack-and-repbox The contact point on the cylinders and using petg filament create a low friction surface. I have come across racheting and clutch systems that are really awesome but I would have either had to reduce coils or create a bulky separate box with those internals that would be great driven. I agree that would actually be a pretty cool design though.
@@jerrari3D Is the filament printed while it's on this? ... so when you're done printing and you change filaments, it will rewind itself? (or is there some other purpose I'm not understanding?).
Thank you for the heads up Michael, I corrected the link in the description. I am testing a few minor upgrades to continue improving the function of the model, so you should see those showing up on there soon too.
