Y6 motors 5 and 6 dont spin up - Pixhawk config problem?

Posted by Snake on August 23, 2015 at 8:07am

Hi,

I'm building a Y6 and all goes well until I try to spin the motors up.

I'm using a Pixhawk and APM planner.
I've flashed V3.2.1 and selected the Y6 (X) frame.
All initial setup goes ok.
I can calibrate the ESCs.
Arming succeeds.

But - when I arm, motors 5 and 6 don't spin up. If I increase the throttle, the other motors react but still no life from 5 or 6.

If I connect motor 5 or 6 to channel 1 on the Pixhawk (where motor 1 was) then they spin up as though they were motor 1. So ESC calibration seems to succeed and the 2 motors and ESCs work.

What I can't see is how the system knows if it is a Quad, Hex Oct, 8X, Y3 or Y6. Can anyone help here?

And what am I doing wrong that the last two motors don't spin up?

Any tips are welcome !

    Hello

    I am also planing to build a Y6 drone. Can I take a look at your frame so that I will have an idea about designing the frame.

    Thanks.

    Hey Snake, you need to run the initial setup in mission planner. There you connect to your drone via USB and get everything set up. If you have problems connecting, adjust your baud rate...

    Hey rhere sorry for your troubls. Is it a pixhawkhawk or a *****hawk? Also, try the following: load up plane firmware on your  hawk, than powerecycle and load copter 3.2.1 and power cycle your machine. Run all the calibrations, in the full parameter list enable log everything in the log_bitmask. Try arming and see if the motors 5&6 spin up this time, if the do not post a log here please along with a picture of your installation.

      Thanks Artem !

      Seems strange but I followed your logic and your advice and I now have 6 spinning motors.

      Problem solved.

      BTW I did revert to Mission Planner as APM Planner refused to flash the Pixhawk this time. Maybe that made the difference Joe so thanks there. But flashing with APM Planner is another topic so another thread...

      Thanks for your help.
