    Re: Dynamixel MX-28 no longer turning

    Just to follow up on this, for people who end up on this thread, I talked to the guy on the Robotis forum and after a lot of experimentation he also gave up and told me to do this RMA process.

    Re: Dynamixel MX-28 no longer turning

    I did mention that I already tried to do a firmware update, using the Robotis software, tried with both versions for dxl v1 and v2, and scanned for multiple baud rates, especially 57600, which...

    Dynamixel MX-28 no longer turning

    Hi,

    So I have the weirdest situation and I don't know what to make of it. I have a chain of 3 MX-28 and at the end one AX-12 (one of the arms in my robot). They are controller by an...
  4. Question(s) Re: RX_TIMEOUT error when setting power to Dynamixel Pro - Raspberry Pi

    My two boards didn't come in any sealed box, just packed in a sandwich of styrofoam. Which wouldn't have been a problem if they worked :)
  5. Question(s) Re: RX_TIMEOUT error when setting power to Dynamixel Pro - Raspberry Pi

    So how is it working? I'm asking because apparently they've chosen to completely ignore my cries for support so I can't find out first hand :)
    Anyway, I'm just curious, I already scratched my head...
  6. Question(s) Re: RX_TIMEOUT error when setting power to Dynamixel Pro - Raspberry Pi

    Yes, Trossen didn't bother to reply to me either. It's been 4 days..
  7. Question(s) Re: RX_TIMEOUT error when setting power to Dynamixel Pro - Raspberry Pi

    So the weekend is over, did it work? :)
  8. Question(s) Re: RX_TIMEOUT error when setting power to Dynamixel Pro - Raspberry Pi

    If they managed to send me two consecutive bad boards, maybe this platform isn't very stable and doesn't fill me with confidence in the long term :)
    Also they were cheap enough to send me the...
  9. Question(s) Re: RX_TIMEOUT error when setting power to Dynamixel Pro - Raspberry Pi

    Should I maybe try to reinstall the firmware on the arbotix pro?:confused:
  10. Question(s) Re: RX_TIMEOUT error when setting power to Dynamixel Pro - Raspberry Pi

    I don't have problems with the pi, my problems happen on both the pi and edison. All the described errors have been reproduced with both boards.

    I read the other threads, I also noticed a weird...
  11. Question(s) Re: RX_TIMEOUT error when setting power to Dynamixel Pro - Raspberry Pi

    Thank you for your detailed answer.

    My problem with the arbotix pro is not that I can't talk to the servos, I can't talk to the board itself, even a simple ping times out. I'm not sure if...
  12. Question(s) Re: RX_TIMEOUT error when setting power to Dynamixel Pro - Raspberry Pi

    Looking in the docs for AX-12, I see a register called Return Delay Time, is this is what you're referring to?
    Anyway, the funny thing is that with the current hardware setup I cannot access the...
  13. Question(s) Re: RX_TIMEOUT error when setting power to Dynamixel Pro - Raspberry Pi

    Hi!

    I'm reviving this old thread since I'm getting exactly the same error.

    Now, just like the user before me, I talked to the company and they said the board must be faulty, they send me...
