    Hi.
    There was a problem during production with the STM32F407G-DISC1 board.


    https://hackaday.io/project/168801-diy-mmos-ffb-stm32-and-servo-drive-servo-motor
    I completed it according to the address above This is the motor used. https://www.aliexpress.com/item/32853791748.html
    As far as Windows recognizes as MMOS2014, it has succeeded, but when connected, the motor rotates to one side at will.
    All wiring is connected equally The AASD setting is the same, but the motor continues to rotate to one side and does not stop.
    How can this be solved?.

    Is PN053 18?
    Is the steering rotation input to the pc?
    Set Desktop Effect to spring.
    What will it be if you raise two slides?

    Yes PN053 set it to 18.

    Yes, it is entered on the desktop.
    For example, I set 900 degrees, but from the moment it goes over 900 degrees, it starts turning in one direction.

    I set the desktop effect to String and tried raising the slider, but the symptoms are the same.

    That is force of the end stop.steering stop
    However, it works in the opposite direction.
    Try changing PN191.
