    Hi everyone ! I need help with my Sabertooth 2x32 arduino uno build..

    Everything works motors are moving but my problem is motors is not running smooth in "Smc3".

    Motors are running smooth when i have PWmax 20 and it wont follow the lines correctly and its slow.
    When i put PWmax is 110 then it follows line proper but the chair lags and jumping around badly.

    Anyone who had this problem? or know a fix please let me know

    Thanks

    Do you have weight in the chair when you are doing testing? Mine is also rough with no weight in the chair, but when I sit in it it gets a lot smoother.

    Also try reducing your p gain (kp) to get the motion smoother.
