Sounds like it could be Direction signal problems.
If the direction signal is not present for a particular axis or is shorted high or low then that axis will only move in one direction.
If the PC parallel port output is only 3.3Volt on a direction pin and the BoB expects to see a 5Volt signals then again the axis may only move in the one direction.
Perhaps check your wiring and the pp output voltage
