Hello Hood.
 I feel like a foul, but the problem was that I inverted the the step and dir inputs when I reinstall Mach3. Insted of setting 3-2 5-4 7-6 9-8  I put 2-3 4-5 4-7 8-9. I don't know why I end up with that combination. The only problem now Is that I cannot make the motor for axis Y move. The other  three motors run nicely.

Ha ha weve all done that

Just have to check your wiring and settings again, if no movement then check with Parallel port cable removed and a voltmeter on the Y axis pins to see if they are getting the correct voltage.

Hello Hood.
Checked my wires and reinstall them. Machine, now running nicely.
Thank you very much.
