Does a 30p microswitch really have that degree of repeatability?

Not saying it doesn't, just curious.

And what about the z axis where you want to detect the tool tip rather than the slide position? That'd be tricky with a microswitch.

I keep meaning to fit them but I have these nagging doubts, everytime I look at it I start drawing long amplifying levers and schmitt opto switches :D
