    HI!
    I'm building my first seat mover, I installed everything, however the potentiometer got me into troubles:



    1. after i started the SMC3 program, both motors stay at the same angle,
    1. however, i closed the SMC3, then open the simtools tab, then turn on the output testing, the "zero" position is different on 2 motors (beginning of the video and 00:29)

    I'm using BTS7960 43A motor drivers and hall sensors

    There is a plotter section in Simtools so you can see exactly what is being read of the potmeters and if they correspond with the motion.
    Maybe you can rule out some components that way.
