Hi sfallan,

Download the Mach3 manual and give it a read.

Also, I posted some Mach3 setup info which works for my system. Depends on your breakout board pins, but some are possibly similar:

You need to identify the port address, activate the axes, set up pins, set up motor calibration, velocity and acceleration, and set up hotkeys to do the movement.

Do you know what pins are used on your board?
