I did some preliminary tests with the help of Jon Elson back in April. Only 
had one motor attached, but it did spin up in response to MDI and jogs. One 
of two things spring to mind..

1) You are using the wrong IO controller - Set EMCIO = ppmcbridgeportio

2) Alternatively, the ENABLE_INDEX for each axis needs inverting.
