“What hobbyist doesn’t want a CNC machine? But realistically, how many can really justify the need for one? Not me, but we did want to learn about CNC machines and experiment with GCODE. If you are wanting to do the same; keep reading… We had an Arduino UNO sitting around doing nothing as well as some stepper motors we rescued out of an old laser jet printer. That’s a good start for the project, but some hardware/software to drive and control those stepper motors was still needed. Oh, and some PVC pipe and connecting joints to construct a mill platform, don’t forget that.”
