    I am working on designing a specialized CNC machine and am currently in the process of determining the electrical system to control my stepper motors. The machine contains 10 stepper motors of varying sizes:
    • 6x non-standard size (2 phase, 5V, 0.34A, 8.5mH/phase, 14.7ohm/phase)
    • 4x NEMA 23 (2 phase, 2.3V, 3A, 3.5mH/phase, 2.4ohm/phase)
    All of the motors meet the torque and requirements for my application. None of them have encoders, so they will all be on an open loop system. Two of the NEMA 23 motors will be controlling the same axis, so I plan on wiring them in parallel. All of the other stepper motors will need independent control. My goal is to drive all 10 motors from a single computing device, but after lots of searching I am still unsure on where to start.

    Any insight or advice on what products to use or how to control this setup would be greatly appreciated.
