Hello Guys!

I'm really new to all this cnc stuff and i want to know how i calculate me step size so my machine jogs 1 unit.

I have a nema 23 steppers (200step) set at 1/8 step and its fitted on a 5/8-10 rod.

I'm guessing 200x8=1600 but after how do i calculate the rod ? 1600x10=16000?

If i want to make it jog 1inch for example what missing in my calculation?

Thanks.
