Re: Steppers getting signal, but not turning

["Scott Holmes" <norgasm-at-hotmail.com>]

What controller are you using?  are the pins mapped correctly to the EMC
pinout?  Does the controller have a DB-25 on it that you're plugging in to?
If so you may have to change around some signals to match EMC.  The easiest
way is to just make up a custom DB-25 cable that shuffles the signals around
as required.
