I don't understand what you mean. Those pin combinations correspond to the step and direction pins of my breakout board. Motor 0 is the X axis, Motor 1 is the Z axis and Motor 2 is the Y axis. Granted the order is strange - XZY instead of XYZ but this definition has been working OK  for years

Sorry guys, my mistake - I was picking up the wrong .xml file at my end.

As John suspects, it could be bad pins on the parallel card or the BoB.

It turned out to be a bad ribbon cable that attached the port inside the computer to the BOB. Those PIC connections are hard to find. Thanks to Tweakie for support.
