3 parts -- the machine itself, the computer, and the "black box" in
between them.

The machine is, of course, the engraver. The computer serves as the
controller, and the black box is the driver.

TurboCNC acts as an interpreter for the G-Code, and sends step and
direction pulses to the driver board.

Your motors are unipolar -- can your board control a unipolar motor?
Does it have 6 conductors for each motor? If not, you'll have to run
them in bipolar mode.

The difference between a bipolar and a unipolar motor is simple.

Take a coil of wire...you have ony 2 ends. That's what is inside each
side of a bipolar motor. If you add a center tap to this coil, you end
up with 3 conductors per side...this is a unipolar motor. By "ignoring"
the center tap, you can run a unipolar motor in bipolar mode.
