Hi all, been building 3d printers for a few years now, but recently decided to take a dip into the hobby CNC realm with my latest open rework. I found a 3d printed 3 axis mill project over on instructables to get the ball rolling, and dug into it, designing my own set of printed parts for it,.. For a hobby mill made of plywood, plastic, generic 'all thread' lead screws, and economy electronics I am actually really impressed by the results, granted slow results, but still, results that you'd not guess came from such a basic machine. I quasi plan on releasing it here, but kind of curious what you folks think about this Lil CNC project? I do sell printed parts kits for this project, but I also make the 3d printed parts available for non compete re-work (points to links above), so i think that still works with this site, right..? Here is a video I shot of the tool path of a ~20 min "hello world" etch (speed up 2.5x for sanity sake). The etch is a modification of the open hardware logo i did, I am finding it a good relatively quick calibration / test etch for whenever I make changes. Close up of the etch job in acrylic (not the first run, but maybe the 5th or 6th) The square border around the logo is 40x40mm for x/y calibration, and the text is at its tallest ~4mm tall. The cutting bit used was a 25deg, 0.3mm flat tip engraving bit, etch depth was about 0.4mm. A deeper etch in acrylic The machine And my etch graphic.
