    hello freinds
    there is also noise like bees from the wipermotors as soon as
    plug in the sim to start
    how could it be possible to get rid of this terrible wiper motor noise?

    What control board are you using? It could be related to the PID settings and you may be getting oscillation from the motors hence the noise.
    Have you tried any other wiper motors?

    wiper motors are usually dead quiet.

    I've had noisy ones during opretaion, but more like they sound like a worn out noise. Replace them or turn up the volume.

    Again, what control boards are you using? Did you try the PID settings? They may be oscillating, causeing a bee noise.

    hello bsft and thank you freind for reply
    Thanos AMC1.5
    no not yet and how?
    would you please explain it more what should i do ?
    ive done with two different pair of wiper motors but got the same result :?
    best regards

    Hello Hoosang, I am not familiar with the Thanos board and its settings, however, I will try to help. I run the JRK, and they have 2 numbers per setting , e.g 2/2 0/3 1/1, but one on top of the other in the jrk utility.
    The way to test may be using the test tablet plug in of x-sim, and move the slider up and down fast as you can till you get some motor movement you like and free of errors in the software of the thanos.
    p is motor speed and oscillation . If the motor runs too fast in any direction, you need to slow it down, increasing the p number does this. For jrk, the bottom p number is speed and the top number is oscillation (buzzing). I increased the bottom number till I got a not too fast, not too slow movement, and the top number to smooth the motion of the motor
    i, usually leave it on its default number.
    d tells the motor where to stop from going in one direction. The d numbers will help stop overshoot of the motor, so as the motor is being stopped, it does not go too far and cause a motor driver error, or something like that. I am not quite familiar with this setting. But I suggest increase this number one at a time until you get a good stopping point.
    It takes trial and error. With wipers I had the jrk at the settings above. With the bigger worm gear motors, it took 4 hours of PID adjusting to get it right, then profile adjusting after that (never ends).
    hope this helps.
    Cheers, David.
