I was meaning the actual version of Mach 3 you will see that from the Help menu then the About Mach.....
Looking at your config it seems ok as long as you have the correct pins set for each axis. There is one thing however, Looking at your motor tuning I would guess you are meant to be using metric units but you have the default set to Inch. If that is the case then go to Config menu then Native units and change to metric. With your settings in motor tuning and Mach thinking its incch your will likely stall very quickly, if not instantly.
