Hello everyone, I have been building a JGRO design router. I have installed the Hobbycnc pro board, with the 305 oz Motors. I went with the acme 1/2" 10 5 start lead screws on all 3 axis. I am getting ready to do some tuning and testing in the coming days. I have looked high and low and tried to understand this tuning thing, but I have come to realize that I need HELP

. I have follwed the manual on calculating the leadscrew distance and tried to understand it. I am trying to understand the revs per unit for my setup.
I am looking for the steps it will take for my setup.
lead screw 1/2" 10 5 start 1/10=0.1 x 5 = 0.5 this is my effective screw pitch right

305 oz motors 200 steps per rev I will be 1/2 microstepping This is where I get lost. PLEASE HELP...............
Thanks
Gerald
