I think you will find the problem is that the pinouts for EMC do not
match that of the Xylotex parallel port cable. Compared to the Xylotex
EMC has the step and direction pins reversed for each axis. On EMC pin2
is X dir and pin3 is X step. On the Xylotex Pin2 is X step and pin3 is X
dir. Unlike most modern PC controllers the pinouts on EMC are hard coded
and can not be changes in software. So, you need to build yourself a
crossover converter.
