I have one of these. Fowler 54-575-600 Electronic Edge Finder with Cylindrical Tip, 0.200" Stylus, 1/2" Shank
I use it with the Shumatech DRO to find edges or the center of something round. The DRO-350 has a feature for that. Eventually I'll wire up a cable that can be sensed by LinuxCNC to detect the edge automatically. It won't help me set up the tool height for a tool table. I have a bunch of TT type tooling so eventually I'll need something for detecting where the tool is. Probably some sort of spring loaded contact that is a precise distance from where it's set.
