    Have you tried refining your SMC3 setting, in particular Max Limits:


    Max Limits Used to create a band at either limit of the feedback range beyond which if the motors move (typically through inertia) the SMC3 will automatically shutdown the drivers and keep them disabled until reset. This is essentially a safety mechanism if something goes wrong. The value can be between 0-255 (however can’t be greater than the current clip setting).

    i saw this and i thought its maybe like my problem, i think that my arduino get overloded so its crash.

    does this faq help in any h-bridge driver, or only for sabertooh

    https://www.xsimulator.net/community/faq/baud-rate-arduino-and-sabertooth.339/

    when i change 115200 baud instead of 500000 in simtools there is no motion , so do i need to ground pin 8 and reset as said in faq?... aif so so all i need to put wire from pin 8 to the motion body or somthig els?

    My guess it is an issue with SMC3 configuration, your hardware, or some combination of both.

    As per previous post, this is the function of Max Limits, which will disconnect if exceeded, as a safety mechanism:

    Moving a motor fast tends to be associated with overshoots.
