First Time User of Basecam and having problems tuning my new BaseCam 32 tiny board
  • GFlight
    Hi guys,

    I am new to tuning a gimbal control board and having a few issues i was hoping somebody could help with. I am on a time crush as i am trying to get this hexacopter up and running before snow comes in Wisconsin US.

    I am trying to tune a Basecam Simple BGC 32bit tiny board to run a two axis gimbal with MOSFET AS5048A,B encoder motors (i currently have the encoders disabled for initial tuning). I watched Mr. Kim Janson's gimbal tuning videos from start and followed it step by step.
    I have the board mounted securely behind the pitch motor on a flat area (Y is top axis and x is right axis).
    I have the Yaw motor disabled (2 axis gimbal)
    When I run the PID auto i have errors of 165,096 and 169,846, which i assume is where my problem is. I have a screen cap. When i am done the camera slowly rotates on the pitch motor, and does not have much reaction when i tip the copter any direction.

    Do you have any suggestions? Possibly a bad board? Bad power settings?
    I have a few photos of my setup also.

    Other possibly relevant information
    -Using V2.6 encoder
    -Powered by a 6s lipo that has a ubec to give 12v to the board (currently the service tab battery meter is 12.7v)
    -The motors and encoders came with plugs on the wires that would not work with the tiny board so i soldered connectors to the wires that would work.
    -I do not have any ferrite rings on the power cables at this point.
    -Camera is balanced
    -Acc and gyro calibrated. Tried 1 point, 6 point and temp calibration with no change.

    Just really need some help with this.

    Thank you for your help and time.

    It sounds like you need more power. Just add power, but follow up that the motors do not get hot. When encoders are connected you can use even higher power settings.

    Some other things to verify

    How solid is your roll installation. I would put some clue to the CF joints to make sure it is solid.

    Does everything move free when unpowered.

    Try to set it up with camera IMU only With encoders you need only that anyway.

    Make sure that the motor axis are configured correctly.

    You should get much higher P and D than 2. Try seeing them manually to 10-20 and auto tune from there.

    Disable gyro calibration at startup. Perform it carefully manually. the gimbal must be completely stationary during it, but position does not matter.

    I hope this helps.
