Eddy Save your self some inputs and just wire the Home and limits in series. If using separate home switches to limits you'll just need 2 inputs and if sharing same switch just one.!

Not sure if your aware or not but by default when Mach homes it just moves one axis at a time so can be wired in series with no problems. You only need on separate Inputs if you change the homing script so all Axis home together. It's actually better leaving in default mode because it's very easy to damage tools etc because when you press Ref all home then all 3/4 axis set off homing at same time and it's very easy for tool to catch something because the Z axis hasn't lifted enough before X or Y drag it into clamps or material etc.
Mach's default homing first lifts the Z axis then Y axis followed by X axis making it safe. In practice when wired in series this also means tripping any switch can set the axis being homed at that time.? Ie pressing X axis switch while Z axis is homing still sets Z axis home position.? Mach doesn't know or care which switch is pressed, all it cares about is seeing the input state change then setting the coordinates for the axis it was homing at that time then moves onto the next axis etc.

Also spotted you have the ABB 355 vfd same has me. I don't see any reference to the water pump on your schematic and I also don't see any reference to it from the VFD so not sure if your using WC spindle or not.? . . But What I do is use the On board relay on the VFD to turn pump on/off this way it's only on while spindle is spinning.
