Making a 10x10cm CNC XY plotter from scrap parts....and then adding a laser to it!
Recently I had a few weeks off and during that time I finished one of my longest lasting projects - the 30€ 3D printer. During that time I got interested in CNC stuff and since I'm so budget minded (courtesy of my empty wallet) I started thinking of ways to make CNC cheaper, better and more available. This might seem like a far stretch but to me it was actually pretty doable. First I started out with what I want my build area to be, 10x10cm seemed pretty good and should work well for what I'll be doing with it. So I took a piece of paper and started drawing what I want my little plotter to be, the 10x10cm build area being the first thing I drew. You might notice that there's a 2x2cm square, that's the bit that will be moving around the whole build area with whatever is mounted to it. When designing most of my projects I just wing it and make whatever looks nice, I can then refine the design into something more sensible. The 2x2cm square was extended to 2x3cm to leav...
