There’s custom 3D printed vacuum nozzles, and a lot of work on a small desktop Grizzly mill. There’s a video demo of the camera in action below, but there’s a lot more CNC mods on ’ website. With a 3D printed mount and a few magnets, this camera can clip right on to the machine, and with the camera interface in Mach3, it’s pretty easy to zero out the mill to within a thousandth of an inch. is accomplishing this with a pen-shaped USB microscope. This means placing the work piece exactly where you want to cut, or failing that, zeroing the machine to a predefined point on the piece. If you need to mill a few bits out of a sheet of metal or plastic, it’s important to know exactly where you’re cutting. A CNC machine can take care of the relative positioning, but if you already have half your holes drilled, you also need absolute positioning. ![]() After what we’re sure is several dozen screw-ups or at the very least a lot of wasted hours, has gotten around to building a very precise microscope camera mount for zeroing out his CNC machine. ![]()
