Building a custom component tester

[fabsiguy]

Building a custom component tester... plan to sent up this way...cpu (Linux) to beaglebone to motor control board to NEMA 23 2.8A stepper motor. The motor will rotate the component at specific degrees (7.5). The beaglebone will gather the signal data (low voltage signal) on 16 pins (channels). Writing custom coding for the beaglebone to save (map) the signal data and compare it to a saved baseline. Any suggestions on doing this the simplest / cheapest way possible? I'm struggling especially with finding a simple plug-n-play usb motor controller / driver. Links to hardware below.
