This is a CNC machine that I made back in May through July of 2010. It is constructed entirely of materials from Home Depot minus the ball bearings and stepper motors/couplings. It is mostly MDF with pinewood used also. The approximate size is 2′ wide, 4′ long, 2′ high.You may have noticed that I didn’t actually cut anything in this video. I never really intended to post this video but I did anyways. The problem with my CNC machine is that it is not very rigid and there were accuracy problems. I built this hastily and Home Depot parts are not too precise. I drilled over a 1000 holes in a PCB as a test and at the worst it was about .020″ off. Not horrible but for PCB work it’s pretty bad.After getting frustrated and spending probably $400, I decided to save myself further hassle and I just bought a CNC machine. If I were to revisit this CNC machine, I would probably replace the lead screws and the nuts and bolts securing the ball bearings, which is a huge job in itself. I probably should have made it from metal in the first place.
