You say your home and limits are shared and homing works, but then that you connected them all together.
Limit switches can be chained together in series so long as they are NC
Home / limit switches need to be connected individually to 'xhome /x-max-limit' or whatever, there are options in stepconf to do it.
But theres a new issue that strted when I reconnected the limits. I ended up connecting them all to the same pin on the BOB, But now the computer wont boot linux if the parellel port is plugged in, it just freezes up
Unfortunately it sounds like your parport may be fried (albeit given the history I might be rather suspicious of the BOB too)
Is your CNC machine powered when you start?
If you have a powered BOB with opto isolators, having it connected or not should make no difference if it is not switched on, nothing should get through.
The pins should be in an indeterminate state until a driver has claimed it and if having something connected to it prevents booting, that is not sounding promising.
One option would be to buy a PCI parport card, possibly a twin port one to give future expansion if your onboard one turns out to be U/S.
A later netMos one should work without problems

It will be useful for expansion anyway and will comprehensively determine if your existing port is gone .

If yo look at the pic of my BOB wit the 6 terminal connector on the left they were originally connected to 2,4,5 and 6 common.
Nothing attached.
What is the make and model of your BOB and please attach your config files (ini and hal at least or just zip the whole dir)

I will have to try and figure out how to get the config and hal from linux later when I go out to the shop.

Oh, and those are changed from my original config on the limits to make it function as it is now.
