So... problem solved ! xD Just after made this post we found the problem.
The cable that we used (11 x 0.34) to made the conections from H6 to the motors had the DIR wire shorted with COM on the Z axys in the midle of the cable. Just did a rebuild the DB25 to used a spare wire and everything works great now.
Tested all the joging, homing, spindle, water pump.... ready to fireup.
Just have to lear how to CAM from SolidWorks now.
So, Thanks again for all the replyies.
Regards,
Lucas.
