I can jog in one direction only. I replaced the BOB (DB25) recently and i also replaced my computer because the mother board was fried.. The Y would reverse for a while but when I made some changes it will work only one way now. All seems ok in the program but may not be. Help Help

Either bad wiring for the Dir pins, bad bob or you do not have the correct pins or ports assigned for the Dir pins.

If you have a spare output on the BOB rewire the X Dir to it and re-assign in Ports and Pins, Motor Outputs to that pin and see if it helps.
