    Hi,

    Just want to show how I did my potentiometer mounting that allows for center position trimming.
    20221216_195510.jpg I 3D print the housing that attach to the back of worm gear motor.
    There's a small knob that's protruding from the gap that you can slide left or right. It will rotate the potentiometer body instead of it's shaft. Doing so will cause the motor to rotate in the same direction. This will allow you to trim the center position of the servo. It might also let you release the SMC3 out of limit lockout.

    This is how the inside looks like

    The spiral shape arms are to absorb any misalignment between the potentiometer and the motor coupler.

    Thanks for reading this.
