Typically, CNC Machines take up a larger footprint than that of the raw material it is cutting. The size of such a machine may have prevented interested makers/hackers from buying or building one for themselves. If you are one of those people then you’d be interested in [Fly3DMon’s] series of CNC Router projects called PhlatPrinter.
A typical CNC Router has a bed that the work piece is mounted to and that work piece stays stationary. The tool then moves in 3 axes, removing material, leaving behind a finished part. The PhlatPrinter works more like a large format plotter, where the work piece is moved back and forth via rollers while the tool only moves in 2 directions. What this allows is a CNC Machine that takes up very little floor space when not in use that can handle any length of material!

Cutting foam is pretty tricky without a hot wire cutter. Don’t have one? Well, lucky for you, [Darcy Whyte] has a guide on how to make one. It takes just over an hour to build, and it costs next to nothing in supplies!
[Darcy] is using an old 9V power wart that he had lying around, but you can probably use any DC power supply. He designed the frame in SketchUp and cut it out with his CNC router, although a saw will work just as well for MDF. A piece of 40 gauge nickel chromium wire was strung taught between two 1/4-20 bolts, with one held back by a spring. The spring acts as a safeguard to prevent snapping the wire during overly aggressive cuts. This may be a simple build, but it does produce a handy tool.
[Darcy] demonstrates cutting foam with his creation in a video after the break. We think he could cut thin plastic with it as well—modify your 3D prints, anyone?—though he may need to crank up the voltage a bit.
