NOTE: This machine is not and was never intended to be a metal cutting CNC mill. This article then, is my version using an old 3D printer and ideas found in online articles and other resources. ![]() So, while doing some googling on this I found an article from the great guys at Flightest RC about using an RC motor to drive a needle (like a sewing machine) for cutting foam and this article also led me to V1 Engineering who has some great ideas for a "Mostly Printed CNC" machine.Īfter all this (and much, much more) I decided how to proceed with my own version of a bench-top CNC for foam cutting and other jobs. ![]() This proved to be a real pain so the next thing I looked into was how to build my own foam cutter that would be relatively inexpensive and easy to build. I first bought some foam board and hand cut a couple of fuselages modeled on an old DW Foamies Juka 40 3D plane. ![]() Of course this led me down several paths. While "impressing" the neighborhood kids with some of my old 3D foamies (small, aerobatic foam RC planes) I decided to work on drawing some plans to help the kids build their own small flyers.
