Re: Encoder Question

Sorry, but I'm not at all sure what you're trying to ask here. In the first place, why are you using a gear if there's no gear reduction? (I can think of one reason, but it's not likely as the question is phrased.) Or do you mean that you are measuring teeth on the bull gear (that is, the output gear of the shooter)?

You are trying to calculate "distance per pulse". There are no lengths in your question, so whatever you're asking, there is not enough info. What is the effective moment arm/radius of your shooter?

---------------------------------------------------------------------------------------

OK, trying to put together something reasonable: You are counting teeth on the last (output end) gear in your shooter, which is rotating at the same speed as a wheel X inches in diameter. The circumference of that wheel is πX inches. The distance that the edge of the wheel moves per pulse (assuming one pulse per tooth) is πX/40. If there are p pulses per tooth, that becomes πX/40p.

If my assumptions aren't right, please post the corrections so we can help out.
