i have this 5 axis sainsmart breakout board, and i cant find any documentation for how to wire the BOB to the stepper drivers. I have spoiled myself with gecko 540's with prewired db9 cables in the past, so ive never wired a BOB like this.



The BOB looks like this:

Attachment 258386

Sainsmart 5 axis Breakout Board


The Motor Drivers look like this.

Attachment 258388

FMD2740A Controller

Any help on the wiring to these would be very appreciated. thanks for your time, and hopefully knowledge
