Crazy Yaw issues (moving even if disabled)

  • I have a DYS eagle eye, second hand. It's newly balanced.

    Imus are calibrated, fresh battery, wiped the firmware to the latest stable.

    The Yaw output however is crazy. It just oscillates perfectly a few degrees. The monitor window shows a perfect sin wave on the axis.

    When i try autorune for yaw the software just alerts to missing steps and turns yaw output off? Oddly enough however the Yaw keeps going...

    Even when i manually disable yaw output the motor keeps doing this? It will only stop of i disconnect the Yaw lead from the board.

    Anyone else run into this? Testing with a multimeter? Just get a new yaw (one with encoder would be good).
