I have a millport mill (similar to a BP series 2) that I have installed ground ballscrews & am getting ready to CNC it. I can buy a ready built kit from AJAX for about 4000$ but I think I would rather do it myself for the learning experience (and less $). Initial questions are:Steppers VS servos, I've been told that servos are more accurate (Servos have a built in encoder/resolver & steppers do not?) but steppers are simpler to setup & less $. I want this machine to run off of a PC type computer so can I use either steppers or servos? In addition to the PC what components do I need for each axis? If I want servos is there a company that makes servo drives for home builders? If I buy the servos off Ebay do I want brushed or brushless? AC or DC? High voltage or low voltage? Similar questions if I go with steppers? How do I know what size motors to buy, what holding torque vs running torque?
