Now we're getting somewhere. If you get half the distance you expect, that means EMC is putting out half the steps that the machine needs. Steps per rev, microstepping, screw pitch, and all the rest are numbers that you are expected to know when you are building a machine. If you buy one that is pre-configured, the manufacturer might not tell you the numbers. But they should be in the manuals somewhere. (If not, shame on Sherline.) In your specific case, you told it 400 steps/rev with 0.5 microstepping, which comes to 800 steps per rev. You got half of what you expect, so the actual must be 1600 steps per rev. I bet the motors are actually 200 per rev (that is most common), and they are doing 8x microstepping to get 1600 total. So, try 200 and 8x microstepping and see what happens. Disclaimer: I don't have access to a Sherline and I haven't used stepconf, so some details might be fuzzy. For example, I don't know you tell stepconf to use 8x microstepping by entering "8", or "0.125".
