Derek,

Here is the pinout from the NIST website

The pinout for the EMC stepper motor interface is as follows:

Output Parallel Port
------ -------------
X direction D0, pin 2
X clock D1, pin 3
Y direction D2, pin 4
Y clock D3, pin 5
Z direction D4, pin 6
Z clock D5, pin 7

Input Parallel Port
----- -------------
X/Y/Z lim + S3, pin 15
X/Y/Z lim - S4, pin 13
X/Y/Z home S5, pin 12
