SoftMotion and Raspberry pi

  • YouMotion

    YouMotion - 2021-05-18

    Dear All,
    I am trying to understand if raspberry 3B+ or 4 is suitable for softmotion application where needed axis synchronisation (for example gearing two axis).
    Since the softmotion package is available for the raspberry runtime I assume that's possible but on the other hand I found forum talks where it is told raspberry is not real-time and therefore not suitable for soft motion application.
    Can you please help me for a better understanding?

    Thanks a lot

    depends basically on which drives you want to use. (Ethercat / CANopen / Stepper...)
    In general you need to have a rt_preempt patched Linux kernel,
    then I would say the Pi is motion capable.
    That's it.

      Thank you for your reply. Do you suggest to use the Pi 4 with multicore license or the Pi3 B+ should be enough?
