Re: What wheel to use for the flywheel

We also incorporated the use of a PID using the VEXPro Versa gearbox with an integrated encoder using a 2-775 Pro setup.

The biggest factor we are finding are orientation of the balls as it enters our metering wheel and then shooter. Orient them all the same way and we will hit 29 of 30 shots. Orient them another way and we will miss practically all of them.

So how do we account for it?

Well, thats today and tomorrow's adjustment.
If that doesnt work, we will live with what we have.

If we slow things down a bit, we can achieve close to 80% accuracy.
If we shoot as fast as possible, we can shoot 30 to 35 balls in less than 5 seconds, making 50-60% of the shots.

Hopefully, with our adjustments today, we can shoot fast but achieve a much higher success rate.
If we can do that, we plan to share it with all of our Hawaiian friends here.
I totally agree that you need to control how the ball enters the flywheel.

That said, I have a few specific questions:
1) what wheel are you using?
2) what compression are you targeting?
3) what exactly do you mean by a "metering" wheel? (I have a guess)
