Complete CNC conversion kit(less PC). Ball screws, closed loops steppers, digital encoder, Acorn control board, upgraded software that includes threading and MPG. Very few hours on this equipment as its a hobby lathe for me(rarely ever used, reason why I removed the conversion). Fairly confident that everything need(less some wire fuse holders....) to do conversion a couple of hours is present. Because I am not electrical engineer some wires will be removed (especially power supplies) before being Sold. Buyer is responsible for checking all wiring, connections and anything else that can be a safety hazard.
