Hello @andrespalomino ,

It is possible that during crash the motors have sustained some critical damage. Since you indicated the motors "burned" that usually means the winding insulation has melted and there is probably internal short inside the motor.

when you say motors spin correctly when they are separately - are all 4 motors spinning at the desired 4500 rpm with very little current, if tested individually?

Hopefully the ESC is still working fine (please check it for any indication of burned components).

You can do a quick test in open loop mode before replacing the motors:

python voxl-esc-spin.py --id 255 --power 10 --timeout 1

This will apply a fixed power of 10% and it is a very "gentle" test mode to make sure the new motors and ESC are working properly. You can test with propellers or without (maybe better without propellers at first). All 4 ESCs should spin around the same RPM and current should be very low. You can increase the test duration from 1 second if all goes well.

As next step, I would suggest replacing the two motors that are not spinning correctly. Burned motors typically means they need to be replaced. After motor replacement, you should repeat the spin test in open loop mode (in previous step).

Also, are you able to share the motor and propeller used on your vehicle?

Hi @Vinny
Sounds good. I have order number 3143. We have the Voxl1 version ready to return.
I'll be here for further instructions

Thanks

@andrespalomino if the lens is really loose, then the lens could loose focus as it gets rattled with vibes.
Verifying that below is your camera:

When you state that you can get the focus good on the ground but when flying looses the focus, do you mean you can see it gradually getting worse over time or all of a sudden? How far are you viewing the feed? Also, how high are you flying? Do you see a difference when you are closer to objects or lower to the ground?

You need to use a supported camera configuration. You cannot plug different sensors into different locations. C6 and C9 are supported for TOF. https://docs.modalai.com/voxl2-camera-configs/

If different sensors are plugged into different locations, undetermined behavior will occur

@Eric-Katzfey I updated to release 0.9 and that solved the topic.
Thanks!
