Home switches not "seen" by linuxCNC

I have been working on rebuilding my CNC'd 3 in 1 that a friend built me years ago. I have most everything working again but Home Switches. I have a CNC4PC C-10 BoB and my switches are wired NC in series to pin 12 (also tried 11) just as shown in the C-10's manual. I have tested continuity and function of the switches at the wires that connect to the BoB and they are functioning as they are intended. It seems no matter what i try in stepconfig wizard that LinuxCNC just doesnt see the connection. Any ideas of what I can try or a way to see if the signal is getting back to Linux?

Also, I am completely lost in the Linux O.S. if a have to install a tool or something I will need a step by step. Im learning, but its a slow curve.

Got the ptest paralell port test working. No matter which input i connect my home switches to i get no feedback. Strange that the Estop does work properly and its on the same input rail. Testing continuity at the wires from the limits that would connect to the BoB shows closed normally, and open when i press any one of the switches. I swapped to a new cable from the PC to the BoB and no change. I tried to add a dual P-port card i had but could not figure out how to get linux to recognize it.

Build your basic setup in stepconfig and dont look back.

Get into the hal file and tweak from there.

Just a thought

I have, thats when i found my home switches not functioning. I clicked home all and my Z hit the switch and continued in the same direction.

I dont like to, but i am running it with the home switches unused right now and just manually calling home in a near home position. and zeroing my DROs in that position in case for any reason i loose position and need to continue a program.]

I tested that, found 5v at the BoB and 5v through each switch broken when toggle the switches.

Not sure what you mean. Disconnect the common wire, the one going to the ground pin of the bob? What am i looking for results in, Ptest?

They are wired as shown here cnc4pc.com/Tech_Docs/C10R10_WG.pdf

Yes the jumper is in 'pull down' which is what is said to use in the full BoB manual. I have effectively tested 12, 13, and 14 by trying them for my switches. I will try it direct also, then try the db25 cable test.
