CNC Conversion for Smithy

I am new to CNC and am going to convert a new Granite 1324 to four
axis cnc for the main purpose of making micro jets and micro
turbines.
I already have a source for motors and mount kit, but wanted to know
if anybody has experince with gecko 201 drives and where can I get
plans for a power supply.
What is the opinion on mach1?
Also does anyone have info on microjet compressor blades, cad
drawings or G code?
