Whatever method you choose to do DON'T WAIT 12 years like I did before installing this X & Y proximity switches. They're so easy to install even a legally blind person (given enough time) can do. They are soooo worth it. I'd smack myself upside the head for waiting so long before installing them, but my surgeon advises against further damage. ;)

Wow, thanks for the great advice everyone! I'm definitely feeling better about this....
Our background is that we just bought a PRS Standard 48x96 after feeling like we were outgrowing the 18"x32" laser engravers we usually work with. We have 8! Eight! It was time for a bigger machine. We are primarily a jewelry/accessory company, but my department gets a lot of orders from our retailers for custom signs & retail display stuff, and I was losing patience with having to scrap together big work from small parts. I'm really excited about getting as familiar with the CNC as I am with laser engravers, it is very liberating.
Roney, where in Brooklyn are you?
To add to Tom's technique - in the ShopBot setup routine, you can setup your xy zero offset from the prox switches. This allows you to simply hit C3, and it will automatically zero it where you want - no need to manually enter any offsets for your chosen locations.
Thom, my "bot" is located @ 3rd Ward in The Bushwick section of Bklyn. I'll pm you my info...
