I'm planning this with my Chester Mill CNC conversion, I've become accustomed to being able to shut down my X7 and know there will be no positional errors when I turn it on the next day, select the WCS and slot a part into a fixture, I can't imagine going back to having to indicate every time I fire a machine up, I don't think a homing system which requires you to re-indicate a fixture which hasn't been moved is acceptable, in fact I think that's the definition of Useless.
Why not have 1 NC and 1 NO, then it wouldn't matter whether you wire in series or parallel

It took some time for me to understand the second part of the reply as I don't get what part the Wildlife Conservation Society play in CNC. If I am cutting a few parts and have to turn off the machine then I zeroise the Z and 'Ref All Home' to send the X and Y back to the zero point. That way, when I switch on the next day, I know here the machine is.

BTW, I love these things, Engineers Lego......
