Level Winder spooling machine

But at least you wind the filament up untangled, and that is something.

I will latter on provide the motehrboard and algorhitm to separate teh level winder from the spooler and drive it proportionally with a pairing algorhitm.

The problem is that each new row is a tad longer due to slightly larger diameter, so let's assume first row, diameter 62mm width 30 filament strings (60mm) comes out perfect, second row is not 62 mm diameter anymore, but is on top of that, making it 65.4 mm diameter, but mechanically tied level winders  with a belt from pulley to pulley like this cannot compensate for that on the flight, so second row will not be as perfect as the first row, third row even less, and you go 28 rows up.... at least untengeled.

But this can be tackeld with an arduino, two separate stepper motors talkimg to eachoter, and and algorhitm so that when the spooling motor has counted 30 rotations and it starts the second row, the level winder motor adjusts itslef to return at the end after a slighlty longer period. Industrial machines have that for 100 years, so I think it can be done.

But for now is mechanically coupled with a belt, and you don't even need motors, you can print yourself a spools clamp, clamp it on the spool, and rotate by hand to respool occasionally, it works, i tested it respooling more than 10KG.

This level winder machine if you go to buy it with all the mechanics and electrics plus electronics and codes, it goes areound 3000 USD or more, if you buy it from me as STL files, is 40 USD per version, or all versions bundeled in one (the only thing that differentiates them is the core aligner, so you buy all cores in one bundle) 50 USD plus some 4 KG of filament, say another 120USD plus some M16 X 300mm studs, 4 bearings OD 36mm, ID 16mm, width 11mm, M16 nylock nuts, washers, rubber O rings, a bunch of M3, M4 and M5, M6 bolts, nuts and threaded inserts, sealant glue (structuralsilicone) you have it all around 200 USD, plus motor and electronics, maybe 300 USD. Plus a week of printing, filing, sanding, lots of sanding, drilling, inserting threaded inserts with the soldering iron.
Nice savings.
