thanks ger21 for your replay

the choice of the right gear may also depends on the size of motor (Nema 23 or 34) due to the max speed after reduction obtained.
i also like you suggest Nema 34...

my machine dim. is (2400*1200*250) rack and pinion X Y with gear 2:1 or 3:1 or 5:1 ratio. used for wood, plastic and thin aluminum
i need to choose from to kits

1- 4 Nema 23 425oz 3A 6Hm...

i need advice with appropriate gear ratio

thanks

is it better to use this gear 5:1 ratio -untitledaaaa-bmp

I read that high ratio need the stepper to run faster and loose torque in case of Nema 34
is this ratio or 3:1 is siutable to these...

I plan to construct 3 axes CNC router for wood, plastic and thin aluminum. The characteristics are as follows:
