Z-axis limit switches December 26, 2008

I have started installing the limit switches for the different axises starting here with the Z axis. The limit switched trip when the axis is almost to the end of its travel so that it will stop whatever the CNC is doing to prevent damage. These pictures show both the top and bottom z-axis switches and the tab I installed to trip the bottom switch.

So does it then talk back to the computer to say there was a problem? Or does it stop there, not to start again until a human interferes?

The computer polls the switches each step it makes and when tripped stops everything (or what ever I want it to do)
