Ok I see you have shared the limits and homes for the X and Y but the Z has separate.
That should not be a problem as long as your Z Home switch is working.
You mentioned during the testing on the bench that when you did a ref all and pressed the Z Limit the motor kept turning, that is normal as I explained earlier. If however you press the Z Home switch it should stop, reverse and then stop when you again release the switch, does it do that?
Regarding limits and Mach, as I mentioned I had asked for an option of having Home switches adhered to if using seperate homes and limits but that never got done, should be fine in Mach4 I think but no chance in Mach3 now.
Personally I do not rely on software for limits, powerful machines should really have hardware limits, I do mine via safety relays, that then kills the drives, so even if for some reason Mach ignores my home switches when homing then the limits will kill things for me.
Below is a pic of a section of the E-Stop wiring on one of the machines.
