I have a G0704 I am converting and need some help

I would like to know where to start on the steps per.

Is there a general starting point?
C11 BOB
X,Y nema 23 570oz-in
Z nema 34 906oz-in

Ball screws are RM-16 Metric C7 grade ball screws. 5mm Pitch (.508 TPI)  if this helps not sure how to figure it out.


Thank you
Joseph

There is an example of the calculations here http://www.machsupport.com/forum/index.php/topic,12512.0.html

There is also an automated procedure 'Set Steps per Unit' on the Mach3 Settings (Alt-6) page.
