wanting to know where to order the LI servos aaron uses for the ind hob cnc conversion. I see that my V3s are in some type of heatsinking casing. I found some but none that meet the LI model requirements. Are they dc or ac and are they brushless or brushed? And where to find ballscrew encoders? I am looking at making a homebrewed industrial hobbies style LI kit for a new machine I have.
