That would to me suggest a bad switch then. Why you see it showing on diagnostics page I do not know. Will look at your xml and see if I can find a problem.

I'll try to explain this. If I home posiitive and push the switch that the machine would hit in the negative direction it will work and vis versa. Seems like I need to reverse the switches? I'm I making any since?

xml looks fine and seems to be working fine here in simulation.
Dont understand how reversing the homing direction would affect things as you have your switches wired in series so Mach doesnt know which switch is being seen.

Afraid not, only thing I can suggest is download Mach again and install over the top of itself.
Worst comes to the worst you could home the opposite way and just set a Home Off value.

Not really sure I follow as you have al X wired in series  so no matter which wire is  which it should not matter, they are only acting as a closed circuit when non activated and an open circuit when activated.

Main thing, I suppose,  is you now  have things working.

Sounds like you are losing steps, try detuning your Z axis a bit, also check the axis for any roughness or binding.
