Here's a link to the Keling Inc. site specification PDF document for this motor. Mach3 is as good as it gets currently, with the free alternative being EMC2 on Ubuntu Linux from www,linuxcnc.org. In Mach3 it is easy to slave two motors to one axis, and to reverse the direction of one of the two motors so they both go the same direction. Just click on the appropriate check boxes in the configuration screens.
My personal choice for the motor driver are Gecko G203V with a Keling linear power supply of 48vdc, 65vdc, or 72vdc. Lots of opinions available on this subject.
