OK here goes :-)

Is there a reason why you used the encoder VI, instead of the counter VI, for this non-quadrature sensor?

Why did you use 6 pieces of tape, instead of just one?

In an earlier post you said that your speed control is accurate to within 0.2% of point. What test equipment did you use to independently measure the wheel speed to make this determination?

Are your motors directly connected to the wheel, or are there gears or belts or chains between them?

What motor controllers are you using for the shooter motors?

What is the range of wheel speeds you are controlling?

Why did you need a custom PID? Did you try other methods (LabVIEW PID, TBH, bang-bang) and they didn't work?
