PERFECT!!!!

Grab a RAMPS 1.4 setup with only 1 driver (for the extruder)

Wire up a few of these


And connect those to a DB25 connector.

Check out the RAMPS 1.4 Schematic and match up

X-Axis Direction
X-Axis Step
X-Axis Enable
Y-Axis Direction
Y-Axis Step
Y-Axis Enable
Z-Axis Direction
Z-Axis Step
Z-Axis Enable

and make sure there's a common ground between your servo driver and the RAMPS board.
