In Mach3:
Go to Config Menu and click Select Native Units
Then select MM's or Inches, select OK
Go to the Settings tab, click on Set Steps per Unit (bottom left, above the reset button), then select Axis you wish to set. The program will ask for a distance to move, then move what it thinks is that distance. You then enter in what the actual distance was, and Mach3 will then give you a number and ask if you want this setting. Select yes, repeat over and over.
This is time consuming. Start with an inch or two, then work your way to the full distance of each Axis.
Do this multiple times until you can consistently move the same distance each time.
