This sounds exactly what I need to solve my switch solution (you can see information on my table setup and why my X limit switches are being replaced to dry out about every 3 days at this thread
http://www.cnczone.com/forums/showth...340#post714340 )
If you are willing, would you please email me any and all information that I need to replace my current limit switch with this solution?

It would be "Greatly Appreciated"...
Thanks,

In my initial testing, the biggest variance that I've seen in homing Z is 0.0002. This is at least an order of magnitude better than what I was seeing with the mechanical switches. I'm waiting for some larger diameter flexible conduit and have not hooked up X, Y (or A ) yet.
The retrofit was straightforward, we only had to make two new trigger blocks for the Y axis and a new switch bracket for X. The new electronics (transformer, terminal blocks and relays) fit in the left side of the cabinet. If anyone is interested, please let me know and I'll post a parts list and some photos showing how we did the upgrade.
