Well, one very important thing (to me) is opto isolation between the
driving computer and the motor controllers.

Other than good filtering, good sense in wiring the grounds, and
making sure that the motor leads NEVER come loose during power up
situations, you should be in reasonably decent shape. Good bypass
capacitors, etc, those are all important as well.
