Check your wiring.
In particular the X axis Direction pin connection.
If you are using the Parallel Port then check your 25 way cable itself.
Also check the wiring and connections to the X axis motor (check both windings are connected).

Thanks for your reply.
I have checked the Dir connections, and all are OK.
Steppers are NEMA 12v 2 phase 1.8 ° 4 lead Resistance/Phase 1.5 ohm
Checked, with an ohmmeter, the the readings, at the X motor, are: A - 2.0, B - 2.2
Y motors A - 1.4, B - 1.6 Z motors A - 1.6. B = 1.4
I will check further, when I have time, and let you know what I find
