Ok so its a mill or router? I am thinking you are maybe meaning that when you command a move of 1 inch its moving much more?
If thats the case then your steps per unit are wrong, quick and dirty way to set it up is use the Set Steps Per button on the settings page and run through the procedure. That will however only be as accurate as your measuring. Proper way is to calculate, for example if you know if the stepper is 1.8 or 0.9 degrees, what microstepping your drive is, what gearing is between scre and motor and lastly pitch of screw, then you canwork it out.
