Converting a Centroid cnc 4 (cardinal) to Mach 2 Need drive board help

Hi,
I have a centroid cnc 4 with steppers. I want to bypass the centroid
controller section of the control and output from the computer port
using Mach 2. Does anyone have experience with just using the driver
boards from the CNC4? How hard is this to figure out? I have all the
turn data and step and direstion for the motors etc. I just need to
know what wires go where to the drive boards OR the way to bypass
the centroid controller?
My focus here is to update to g code that makes since fro my shop.
The centroid is not fanuc based so I cannot use programming from my
other machines.
