Bad switch, faulty wiring... not really enough information to have very many thoughts.

The switches are working and are NC two types. Circuit opens when triggered. The breakout board is the same one sold at omc stepperonline.

When I run ptest I get pins 10, 12, 13 and 15 are green and triggered. Pin 11 is not. Any suggestions on other diagnostics that I could run?

Do you have a link to the BOB? Pin 11 is an input always so configuration is not a problem. Could be a bad opto on the Bob if they use them. I've had a bad opto on a cnc4pc C1 Bob.

I think we have narrowed the problem down to parallel port card.
I have a syba with netmos 9805 chipset.
