Hi,
I was searching for 'cnc4pc' threads and saw this thread. I may be able to help with some of it. I just finished my 1st control box, yes a newbie.

You'll need a power supply for your breakout board with a 5v and 12v output. Something like this one from cnc4pc (A4-power supply).

Looking at the KL-7212 power supply, I'm thinking you'll need to wire your motors bipolar series, using gecko drives' 4-20 (3-25) rule.
Bipolar Series (4.27v, 3.05amps)
Blue wire connects to gecko phase A
Join red and yellow wires together
Green wire connects to gecko phase B
Brown wire connects to gecko phase C
Join black and orange wires together
White wire connects to gecko phase D
On power supply wiring I had a AC cord that had a green (chassis ground),
white (neutral), and black (hot) wires coming into my enclosure. I connected the green wire (power cord) to chassis, the white wire (power cord) to the two red wires of the power supply, and the black wire (power cord) to a toggle switch and from the toggle switch to the two black wire of the power supply. (* I also put a slow acting fuse (7amp) in between the toggle and power supply*)
You'll need some 36k ohm resistors (current set) for bipolar series wired motors.
You'll need some 470uf caps for the geckos
Good luck (did I say I'm a newbie),
Jack
