Proximity Sensors as Limit Switches ?

[Smiler]

Don't confuse limit switches, which are for emergencies, with home switches which need to be accurate and repeatable. Personaly I'd stick with mechanical switches since it is much easier to make these fail-safe compared to purely electronic ones.

Exactly my point. Put much more succinctly than I ever could.

And as Mach (which I use) can use them as both it IS important they are accurate, repeatable and reliable.

So there.
