Actuator troubleshooting
DJI C610 motor controller
Motor does not move
If the motor controller is blinking abnormally or beeping, read page 6 of the manual linked above
Power cycle the ENTIRE system (including Teensy and motors)
Turn the motor by hand to see if you can feel if any of the teeth inside the actuator broke
Check that the cables from the motor to motor controller are not loose or broken
How to calibrate the motor
Arrange the motor so that there is no load on the motor. This means nothing can be preventing the motor from moving, and gravity should not be applying torque to any link attached to the motor.
Hold the button on the motor controller down until the motor starts moving
Let the motor do its calibration routine
Controller should restart and do it’s normal green blinking
