Hey-
I had a minor breakthru with my machine today (luckily not the kind of breakthru where the bit goes thru the board!) I FINALLY figured out how to set up a touch sensor and make it work with the software I am running. I am using the older MS Dos G-Code stuff- not by choice, that's what talks to my machine.
The machine is servo with the srv400 ISA card and srvbox2 controller. I made a homemade sensor out of some bits and pieces I had laying around the shop. If anyone has a setup like this and wants any of the details, feel free to send me an email. It looks crude, but it I would bet that it will accurately gauge the surface height of whatever material I am cutting to at least .005 or so.
Mike
