This microcontroller has 2 modes: default one just converges both guns on your left and right to center (where your seat is looking at), vertical pivot (y) aren't used. Works great for aircrafts and turrets with guns that are way apart.
Another mode allows you to fully converge both guns at the point you're looking at (from the seat obviously). If each gun has X and Y pivot – it will work as intended.
System requires quite a setup, so better check out my test stand with this system implemented to have a better understanding.
