I have found it easier to dial in steps and stuff just using the Configuration menu within EMC not the Stepconf wizard. Just go into EMC using Axis display program (this is default I believe) and go to Tools menu at the top (I think Tool) in the menu you will see configuration. If you go in there you can change the steps and rate. The first number is pulses per unit (inches or mm whatever you are in), They call it offset or something like that but that is all it is. Then under that is acceleration. Those are the only numbers that are needed to control the pulses. If you make the first number 3000 and the second 30 or 40 you will see very fast pulses.
Then just turn off the estop, turn on the power (both buttons top left corner) and then jog the axis.
