Is there anyway to tune the default PID when you use the set RPM command? My shooter motor keeps spinning up over the requested value then spinning back down then bouncing back and forth.

2

Is this in VCS because we had the same issue and resolved to actual PID because we didn’t know how to change the default values.

Yes in VCS. What command did you use to set the motor in your PID loop? Did you use


Motor.spin(vex::directionType::fwd,50,vex::velocityUnits::pct);

? Or did you use open loop control like this

4

We used the Motor.spin command in the PID loop but it seems like using the open loop control would be better as you can control voltage and not just a spinning value. Has anyone had success with the open loop control?
