3 wire proximity switch help

[cropwell]

Hi

JAZZ and I are saying different things.

JAZZ says that the two ends of travel actually only need one switch, but with a trigger point at each end. in the Mach3 config screen the ++ and -- inputs for that axis will have the same pin settings. Mach3 knows which direction it is travelling so it will recognise as ++ or -- accordingly.

What I am saying is that if you are using two switches it is a simpler practice to use two inputs on the BoB. Each input pin needs a pull-up resistor.

Here is a useful document - if you can't see it PM me with your email address and I will send it to you.

Cheers,

Rob
