    Hi everyone
    I am happy with a self-made station.
    I have a question I can't find a solution to.
    using trim, when I make a cut, the station lowers correctly, everything seems to work very well.
    the problem I can't solve is:
    when the tires begin to block I suffer from continuous hops and I cannot understand what value is causing this continuous rebound, I have to leave the brakes and resume braking.
    use arduino and smc3, power steering motors opel stroke 16/1 (800w)
    front motor drive.
    has anyone had this symptom?
    to reduce the effect I have to decrease the gain (a5) with the potentiometer on arduino, but using vr I would like to have good movement to avoid sea sickness. and prevent the station from jumping off the ground by moving forward.
    if you need details or photos, just ask, I don't know at the moment what information you may need.
    with respect Marco

    Have you tried and tested the settings for each axis, as that should help identifying the issue.

    It would also help if you posted pictures of all of your settings.

    Like its unable to stop at its target?
    Could be your PWM settings if so.

    thanks for the answers, now as soon as I log in to the station, I'll do the analysis you suggested. @yobuddy the pwm settings are difficult, it seems more like an exaggerated return of a hop suspension, like the rubber that jumps almost in locking. I have to check that I have not exaggerated with the surge parameter (right?) because I also use it to the third dof to pull the belts .. greetings and thanks again. @noorbeast thanks for the availability I try to investigate better

    hello, here are some settings screens. I hope you can find some anomalies. Thank you

    it does not do it with all cars, only with some ferrari 428gt2, porche911 etc.
    here my son filmed during a driving test.
    as soon as I arrive, place a video showing the skipping on the brakes ..

    You have a Axis Allocation total % that looks way too high.

    What filters are you using on sway and surge? I would not use filters until every other setting is perfect.

    Have you checked each axis with the others turned off?

    good morning.
    today I try to use one dof at a time.
    these are the applied filters
