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
