Re: [CAD_CAM_EDM_DRO] Coordinate Measuring Machine

You can make your own probe. Basically a disk on a rod for the probe,
and it passes through a ring with three contacts on it. A slight spring
presses the disk down on the contacts. When the tip of the probe
contacts a surface, a contact is lifted off a section of the disk,
breaking the circuit.
