I'm thinking about building an ar3 robot many months from now, and I want to use it as a cnc for various machining purposes. I see robots arms like kukas acting as a cnc carving busks and stuff and I am wondering if an ar3 can do the same. I am also thinking about increasing the power on most of the motors so the robot has a greater reach, maybe 36-40'' and increased strength, 50:1 Nema23 for j1, 100:1 Nema23 for j2, 50:1 Nema23 for j3, and maybe a nema23 screw on j5, would that work.
