Title: drives will not reverse
Post by: engineeron on October 23, 2011, 01:45:30 PM
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.

I have all axis working in both directions Now ..except the X  axis.     I have checked and rechecked ports and pins setup  and  all checked to specs.  I was wondering if one wire is wrong on the bob. It maybe something simple.  Help

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.

Thanks for the help... It worked.  I changed the wires on BOB for the X dr.  from  2 and 3   to  8 and 9 :)
