Flight Core PWM ESC Calibration
-
Trying to follow the recommended documentation for ESC calibration
You should hear a second jingle. Wait for the second calibration jingle to complete. After the second jingle stops, press [ENTER] to proceedThere is never a second jingle.. I am not sure the calibration completed. The drone is shaking violently with the voxl flight core, but flies stable with a PX4. I switched back and forth to be sure that the extra weight is not an issue.

Hi @kiprock,
I've not had oscillations myself from ESC cal issue, more generally from PID tunings (I experienced the same when I tested on a tiny frame and had the m500 PID settings still on board). I really lower all PID settings (roll,pitch,yaw) and then slowly bring everything up.
Other's might chime in that are much better at tuning than myself, but here's an example of a smaller frame's settings (https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/blob/master/platforms/v1.10/useeker_v1_config.params#L88)
Are you using the FlightCore FW that shipped with the unit or did you update it? We noticed that with v1.11 there was a change and there's this script that seems to work better.
One way around the ESC calibration is if the ESCs support DShot to use that as it's a 'digital' interface.

hello I have the same issue on (hexacopterx) there is no second jingle I waited around 10 minnutes but it still doesnt second jingle.After this calibration just 2 motors are working.What can I do do you have any experience about esc calibration of hexacopterx on voxl?I am using tmotor esc.

Hi @John-Mccarty , checking in to see if you've progressed at all through this? The process is a little picky and sometimes requires a few tried.
