I have a Pixhawk 2.4.8 from Amazon that I got for Christmas, and I'm really at a loss. I can't tell if this is the same 'ESC calibration failed' or a bad Pixhawk. I've ordered another one from China - by mistake - and I'll have it in two weeks.
Here's what I have:
- X7 Taranis
- FrSky X8R with DJT module
- 3DR type battery monitor
X8R seems to calibrate ESCs
I can get Ardupilot to connect and I can calibrate the radio and compass, but I can't get the motors to spin. If I connect the motors to the X8R and I up-throttle beeps, down throttle beeps, up beeps and down beps - each motor spins on servo/out 1 with power from the PDB with battery.
I've snipped the red wires from my ESCs and use the PDB for power.
No life in ESC from Pixhawk
When I connect the ESCs to pins 7, 8, 9 and 10 from the right with the signal wire on the bottom - nothing. It seems like there is no power to the ESCs. I don't see any motor twitch or anything when connected to the Pixhawk with battery and USB. Ardupilot once actually spun the motors - only once.
Either I am missing a step after calibrating the radio to connect each channel to a motor, or I have a bad Pixhawk - or other?
