    Bloody hell Derick do you realise with 35T and 3.2:1 you have 34mm pitch and with 2000Rpm motors you'll be getting in excess of 68M/min rapids.!!! . . . Tread careful mate the bloody gantry will flying off the end in blink of eye. . .Lol

    Ok well you have 2500 count Encoders which will be quadrature so x4 gives 10,000 pulse per rev.
    Then workout your Pitch which is 35 x Pi = 109.599mm per rev / 3.2(ratio)=34.361mm per rev

    Now Calculation is 10,000 / 34.361 = 291.026 pulses per mm.

    Hope you have a nice fast motion control card because you'll need nearly 300Khz to get full RPM from those motors.
