Thanks Nathan for the reply,
But what do you mean by “poor-fitting PID values”?
Moving the motor via the PWM control is beautiful, can see the encoder values increase and decrease with no anomalies in values being reported.
BUT I since noticed, get a MBLO yellow alert whilst attempting using/altering the position setting via IOStudio. And thinkign about it it, could be impacting the 5V rail which in turn would alter the voltage division across the pot. Which in turn could send the controller in to stupid mode trying to get to position.
Anyway if interested, will report back on my findings.
