Are you using the Star 556 preset?
I'm still working on presets and how that system works so it doesn't work exactly how i want. You have the proper start value, for sure i know that if your using the preset, but the stop value is going to be ridiculously high for what you want.
Do the following calculation to get your stop to be a bit more manageable:
0.015625 * Width = Stop value
The star won't work when your moving (It would be pointless if it did with that kind of spread), but it should when your standing still.
