ive for real been building in my mind all the things youd need to figure out to make a sewing machine &/- embroidery machine and besides the fact that theres just some compromises that have to be made in replacing cast iron parts with anything else i really truly do believe it wouldnt even be that hard. like probably more mechanically complex at the most basic level than a 3d printer but not THAT mechanically complex and a lot of the weird little bits are more or less standardized. you can buy an old style tension assembly for like $10 or something. you can buy metal bobbin cases & bobbins in packs for like $5 on amazon. mostly not sure about the hook assembly part but its probably simpler than im making it in my mind

#ive been focusing on embroidery machines more just because you can find old sewing machines for like under $50 and youll be good #embroidery machines are EXPENSIVE and theyre also filled with proprietary junk #but theyre literally like 3/4 of a sewing machine plus an xy stage. and those DO NOT have to be expensive #i think probably building off reprap itd be easier to make a computerized machine than a manual one because the resources & knowledge #about motor control are pretty directly applicable whereas complex cam systems are a very different & new beast #i think its always gonna take some amount of cams just because a new motor for every single bit would be silly & less reliable #but some of those older machines that pushed the limit of cams trying to do what computerized machines make trivial are crazyyyy
