    Well, it looked better before.

    But each rig is very unique and needs individual settings. So just play with the parameters and check which combination works best for you.

    The link provided by @noorbeast is very helpful for getting a basic understanding.

    it is pretty good

    set
    P = 400
    I = 1

    see what happens

    Different motors need different PID settings! I'll send you my settings for your reference.
    kp=200
    ki=1
    kd=300
    ks=80
    pwmmin=5
    pwmmax=200
    pwmrev=200
    deadzone=1

    pwmmax is basically how much power you want to use. Setting it to 255 means that your motors can run up to 100% power. If you leave it at 200, you are using up to 80% of motor power.

    Some pwmmin may help, I found that 20 is a sweet spot with wiper motors on my rig. I'm also running 255 pwmmax to use all of the available power.
