The EMC-standard pinout, starting at pin1 (parport D0 bit 0) is:

X DIR, X STEP, Y DIR, Y STEP, Z DIR, Z STEP.

Is that your pinout?  If not, you'll need to change it in the .ini:

- If you're using freqmod as your motion module, switch to quickstep.  It's 
better, anyway.

- In [EMCMOT] section, set the QS_PINOUT parameter.  It's an 8-digit hex 
number. Each nibble specifies a parport D0 bit (0-7), and polarity (+8 for 
normally high).  Starting at the LSB, they are DIR0, STEP0, DIR1, STEP1... 
STEP3  //Starting at the LSB, they are DIR0, STEP0, DIR1, STEP1... STEP3

For the standard pinout, you would say QS_PINOUT = 0x76543210;

Make sure you don't try to use the same pin for two purposes.

After EMC starts up, you can run "dmesg" in a console to see kernel message, 
which will include a description of the actual pinout it is using.
