    1000 *3 = 1000
    But it may be 4000*3 = 12000

    Hi Ivano,

    It would be helpful to know what kind of system you have and what software you are using.

    But most rotary axes use units of degrees so the answer might be:

    1000 lines/rev x (4 counts/line) x 3 x (1rev/360degrees) = 33.33333333 counts/degree

    You might just try a number and if it doesn't work measure the factor you are off by and divide the number by that factor.

    HTH
