USB stepper motor controller

jlcarender

I am building a small cnc pcb router.  What would be the best usb stepper controller? to use with 3  4 wire stepper motors.

  • Hi joe,

     

    It depends really on how deep you wan to go, if are not afraid to open up an IDE and rattle up a software/hardware based PWM almost any USB enabled MCU could be used to do the job.

     

    One option to have a look at would be the application notes + developement kit from TI, DRV8824EVM unfortunaly this only details a Bi-phase system.

     

    Microchip also do a really good Dev board DM330022 with excellent application notes and exaple firmware already set up to prototype a motor controll application with devices capable of driving the stepper motors.

     

    The only other "problem" is the control side from the PC/Usb host. FTDI / Microchip and Ti provide easy to access windows drivers allowing you to generate the control application from a whole host of platforms.

     

    If you supply a little more info I will be happy to go into a little more depth.
