Limit switches are usually wired Normally Closed (NC) this way if something happens to the wiring ( a break or disconnection) the machine will stop. If wired Normally Open (NO) the controller will not react to a broken circuit.

The touch plate would be wired Normally Open and use the probing routine. See this thread for a neat application: XYZ Probe modification

http://pminmo.com/home-and-limit-switches is a good article about limit and home switches. If you go to the home page: http://pminmo.com, there is an articles section that you might find interesting.

What type of controller are you using?

Hi Bob,
Im using one of the old custom made deepgroove1 controller and mach3. I already connected the touch probe and its working really well. But now I also want to add limit switches. They are already installed, but I´m not sure where to wire them.
I think this deepgroove1 controller is pretty similar to the xylotex controller board..
thanks Christof
