    Hi,

    I've been working on this issue for a few days. I am able to set the my motor's settings with SMC3. The motion is smooth, however, once I sit on the rig, the motor settings are not "strong" enough to move the rig under some weight. If I increase the PWMMax, the motor can move me with no issue, but the motion is jerky. I have attached my settings.

    Any help is much appreciated.

    Try Fpwm at 25.

    Thank you sir. This helped a lot. I set the following

    Fpwm - 25
    PWMmin = 10
    PWMmax = 90
    PWMrev = 90

    The motion is much much better and it can handle my weight. This is a good baseline that I will further tweak!

    You should create your own thread in an appropriate section detailing the issue, what you have tried and post pictures of all of your settings.
