Thank you. I missed the touch part with the inclusion of micro switch talk. My bad.

Is someone really smart out there looking at a G38 macro to implement this?

I've written gcode (really simple gcode), but never a macro before.

Jarretl posted a macro here when I was wondering about ATC (thanks Jarretl!) and think this is the best approach I could get with the S3. Since then, I started using chillipeppr and its great

I intend to install a spring-loaded touch plate at a fixed location so the machine goes automatically to that position after the tool change, apply the offset and resume milling.

Check this one out. . . 50mm is about the smallest you can find & its pretty cheap comparatively

But if any of you come up with a functioning Z-Zero Setting Probe/Z-Limit Switch already wired for the Carbide Board, I'd be happy to buy one off ya.

Maybe I'm just lazy, but I want a moveable touch plate. I'll place the touch plate on top of the material to be machine, jog the bit to directly over the touch plate, then run a macro to determine the new Z axis zero for this bit.

Auto tool changers are way cool. The high school has an 8 tool machine. It keeps a tool length offset table instead of a touch plate. The machine's name: "Sweet Vickie". It's true.
