I’m trying to get my quad setup but am running into a problem with my navio2.
After I power on and wait for the Pi to start, APM starts (I’m guessing from the LED lights). After apm starts up, all four motors start spinning, slow, like barely able to keep it that low, but still spinning. I can arm them and disarm them normally, but they never stop spinning.
In addition to this the gimbal isn’t working right either. Everything is configured exactly how I had my Navio+ last week but now I’m getting these issues.
I have tried recalibrating the ESCs 2 times but still the same issue.
Just an update, I tried uninstalling and re-installing apm and still the issue is there. When I ssh, the motors start the spinning as soon as I start APM and stop as soon as I stop APM.
Another update. I am getting power through the servo rail from the power module. Isn’t this not supposed to happen? I thought I had to power the servo rail using a bec. I can unplug the bec, plug in the power module and the radio receiver (connected to the PPM part) still receives power. Is this a faulty board? could this be part of the issue why my motors are spinning once arduCopter starts?
One last update. Now, when I plug in the bec into the servo rail it causes the navio2 AND raspberry pi to shut down. But I can still plug the bec straight into the radio reciever and use a esc calibration thing to test the motors and they work as expected.
This is a feature. We are powering receiver from the power module, so that you don’t have to use BEC for that. The rest of the servo rail is not powered from the power module.
I’m not sure what passthrough mode is, but I did try to set the 5th pin set (and then 7th to see if it changed) to a gimbal. I first set it to say “servo” because I think that is what I did on the navio+ to get it to work. Is that considered passthrough mode?
What about the bec causing the navio and pi to shut down and not start? Is that part of the same issue with passthrough?
Here is brief overview. ESC’s are plugged into 1,2,3,4. They only have a signal and ground. But the extentions I’m using make it look like there are all three. But the power part isn’t plugged into anything.
Pin group 5 I tried to plug in the gimbal, again, it will look like all three cables are there but it is only the signal cable that actually gets to the gimbal.
In the last group of pins (I forget the number) was where I had the 5v from the bec going.
the only other thing plugged into the navio is the power module cord from my power module (an aftermarket one that can handle 6s).
If you do not enable the gimbal, do you still see the issue? As @pierig correctly pointed out there is an issue with that currently. We are working on it.
did you check the BEC voltage? (because just a little over can be a problem) only to double check if its ok. did you have the problem without bec and guimbal ?
and if you connect only the ESCs and motors without Navio board to the battery (without the signal wire to Navio), are they spin ?.
I can connect the motors to the battery and the ESCs to a calibration thing and connect them to the throttle channel on the receiver and they work normally.
After set your MOT_SPIN_ARMED parameter to ZERO, “no spin” in APM paramenters
Other thing, is recalibrate all ESCs , using APM. (WITHOUT PROPELLERS)
never can spin without ARM - really , really dangerous…
