$250; Pushing The Limit On Cheap (And Functional) CNC Machine Builds

Cost is always a drawback and a hurdle when buying or building a CNC Machine, especially when building it just for fun or hobby. [Eric] was able to cobble together a working 3-axis rotary tool based machine for about $250, a few trips to the hardware store and a bunch of time. The machine design is loosely based on this one he found on Instructables. [Eric] chose this style because he felt the boom supported tool would have been more stable and easier to build than a gantry style machine. Skate bearings, HDPE sliders and c-channel aluminum were used to support the XY table instead of traditional linear bearings and rails. All three axes are driven with stepper motors and 1/4″-20 threaded rods. The Harbor Freight dremel-style rotary tool helps keep the overall cost down. [Eric] is going really old school by using TurboCNC as control software. TurboCNC runs on DOS and DOS-ba...
