200 steps per revolution x 18 turns per inch (5/16"-18 rods) = 3,600 full step or 7,200 1/2 step and so on depending on the step jumpers you set on your board.

Any pictures of your machine? like to see a post on it.

I don't know what this means? Do you want to set up the machine in inches or mm's?
