Here's a question for you - If you are using one switch for home and limit does Mach ignore the limit function while homing?

Yes if you turn off HomeSW Safety in General Config.

That leads on to another - If you have slaved motors on an axis does mach wind both motors until a home trips and then keeps winding the untripped screw until the other trips, thus squaring the gantry and then do the backing off the home switch to complete the homing and aligning process ? In which case I presume you would need to have separate inputs for each side of the machine.

When using slaved motors Mach De-couples each motor turning back into two separate axis while homing happens which means the motors work independantly but move together in sync towards the home switches. When first switch is tripped that axis motor stops and backs off the switch while the other keeps going then does the same.
In practise provided your Gantry is square and the switches positioned correctly this appears to happen has one action. If your gantry is really out of square then you can position the switches to force it square.
When Both Motors have homed then Mach Couples the Axis again back into one slaved axis.

This does mean that the Slaved Motor needs it's own Home switch on a Separate Input.
