Hello
I buy used ball screws 2005 with stepper motors oriental pk299-e4.5b. About stepper: 8 leads, 4.5 A, 2.8 V, 0.66 Ohm, 2.5 mH (each phase). On back shaft of motor was hand made "encoder", photo: https://imgur.com/a/yShHP. Motor driver is 1421.012.04, 1421.017.04, nothing more is written on driver, google search found just: 1421.012.04, 1421.017.04 Circuit Board T63918

So I want use this steppers as stepper motor. So I need your help to choose stepper motor driver and power supply for them. Budget for stepper drivers is not big, so Gecko is too expensive.
