This is a small electric touch-plate for auto-probing the Z-height for a CNC machine. It's designed for the MPCNC with a common "Chinese" spindle. I think it should work on any hobby CNC, although the spindle-mounted electrode might need replacing with a clip.
It is designed to screw down (M6 holes at 10cm spacing) onto a CNC work-bed. It uses a small piece of plain copper PCB board from Maplin (35x40mm) as the touch-plate, and a 608 bearing with a wire soldered to it as the spindle contact.
