    I have a problem perfectly synchronizing the 3 curves, during sine or movement tests, the motors have difficulty following the light blue line of the emulated knobs....

    Do you have the solution?

    My motors are 250 w - 75 rpm, 24 V (wheelchair motor)

    Nobody here ?
    I have the impression that the arduino program applied a filter which smooths the response so that the motors do not exceed the limits....

    I tried to remove the limits to see, same thing.

    In the simulation everything works well, and the feeling is impeccable, but I still don't understand why and where to look, if I refer to what I find here on this forum, the 3 curves should marry...

    Ok, I found on a page lost in the middle of the forum dedicated to SMC3... I had to reload the SMC 3 v1, the one given by Ronan which served as a basis for me was not good.......... So if you have the same problem, reload the SMC3 V1 version and everything is back to normal! THANKS. Sincerely.
