Taig limit switches

Hi Folks

I have a Taig mill,converted to CNC control, driven by Mach 3. I have
used this for a couple of years without the benefit of limit or home
switches. I am now considering the installation of these switches and
would appreciate some input.

Has anyone on the list added limit and/or home switches to their Taig
mill? If so, could you give me a quick run-through on how you did it.
A link to a website with illustrations would be much appreciated.

Thanks.

Keith
