Trying out the idea of building an optical toolsetter for my machining center. This is a super quick rough prototype using an Arduino and a cheap photo-interrupter. Seems to repeat within about 0.0002" which is pretty amazing for such a lashed up rig! Seems like it might not be a crazy idea to build one, buying one is very expensive!

The toolsetter is basically a device that talks with the CNC to accurately measure the length and diameter of your tools. They can also be used for automated tool breakage detection.
