Tweakie.

You've not provided enough information, as we need to know either your Z screw pitch, or Z axis tooth spacing/pitch (you say pinion, so I'm going to assume you're using a rack?)

If you want to understand how to calculate the steps, have a read of this article - http://www.uk-cnc.com/2015/07/25/calculating-steps/

i dnt need Z axis dear X and Y axis enough for me calculation..

İ need Formule dear.. i have many documents about that but when i test .. step per is wrong so i wrote my specifaction.

You need to determine the Pitch Diameter of your 40 tooth pinion.
