yep :)

@jojje123 I definitely agree this might be the issue. Perhaps if I run the Arduino with the throttle power output and ground?

Nice. Thanks. Perhaps I can reduce the cost/complexity a bit in the future by swapping the DAC for a simpler RC filter (version two). I'll post what I learn from the potentiometer test.

Gotcha, thanks. I do already have the DAC running (via I2C) from the Arduino to the throttle, rather than just PWM. Will definitely try with a simple potentiometer for a sanity check. Sure hope I don't end up dealing with allowing current to the signal while the whole thing turns on, what a...

@Ianhill... The third power wire (red) is connected to battery. I believe that if it wasn't connected the self-learning wouldn't be spinning the motor at all. Great to know that the brakes being disconnected is not a problem. I haven't had any trouble with the self-learning system, that's...

Thanks for the replies. Seems reasonable that the controller could get locked up if the throttle wasn't plugged-in when started up. I did try connecting the 5v throttle output directly into the signal wire, but it wasn't connected initially (and the ground was then disconnected). With the...

I'm trying to control a brushless hub motor via Arduino by way of the motor controller's throttle signal. Getting no spin :( To troubleshoot and calibrate I output a signal from the Arduino between 0v-5v to the throttle signal wire (green,vs red/white). I've tried voltages all over the range...
