Problems with roll motor control
  • srinath
    I have a new 32-bit alexmos controller from Viacopter. IMU is calibrated and moves logically on the GUI.
    However when i connect everything, the roll motor doesn't respond to the RC at all and just oscillates.

    The pitch motor follows the RC, but near the end of the travel it starts shaking violently
    I am using the default factory settings & behavior is the same with and without camera.
    Here is a video


    I don't think it's a motor problem because swapping the roll and pitch motor cables transfers the problem to the pitch motor.

    I am using an Airtronics RDS-8000.

    Could someone suggest a way out? I am stuck

    You need to have camera installed and gimbal balanced for it to work.

    I tried it with the goPro-3 camera attached and results were similar.
    I am using the Vector-DD Gimbal mechanism

    Then probably basic settings are wrong (motor inverted status, IMU orientation, Power settings etc.) or it needs to be better PID tuned. It could be so many thing it is really impossible to say what is wrong.

    You need to set it up carefully with the users manual http://www.basecamelectronics.com/files/v3/SimpleBGC_32bit_manual_2_43_eng.pdf

    It is of course possible that something is broken, but more likely that it just needs to be set up correctly according the users manual.

    Hi, Attach your camera to the gimbal. Rebalance your gimbal and tune the PID values.
    Please, read the manual: http://www.basecamelectronics.com/files/v3/SimpleBGC_32bit_manual_2_43_eng.pdf
