Is the BOB in a metal box? A simple one could be enough ti ground the board.
No, it's not in a box, but it is inside a metal cabinet along with the 3 servo drive boards, and 12v power supply.

Did you ever try the caps on the limit switch inputs to your BOB?

The BOB grounds through the PC via the shield on the parallel cable.  Did you ground the PC chassis or try soldering a ground to the DB25 shield?
