They dont need to be all the same, X, Y and Z can all be different pitches and you just set the steps per mm or inch in mach 3.

The only exception to what Chris said above is, if you have a dual drive slaved axis.

For example one motor each side of the gantry, which is a common way of doing it.

Then the master and slave axis must be the same steps per unit. (or same pitch lead screw)
