Wrong Direction

Hello

Well,I've been working with my cnc machine for a long time without problems but
suddenly one day the x axis stopped working. I found out that my "gecko drive"
was burned,so after replaced it, everything seemed to be ok and after test it
I found that there was no direction change in the servo. My parallel port is
configured in the same way as always but the direction state is always "1"
(In the jog mode after I pressed + or - the servo always go in the same direction)

I tried to invert the pins in the parallel port and nothing happens.

I don't know what else could it be,any suggestion?

Thanks in advanced
