CAD model here. Software stack here. Preferred slicer here.
The software driver stack Installs cleanly onto any new Raspbian installation. It includes a touch-screen interface which is also served as a web-page for remote access. On the back end, it has a sophisticated GCode sender that works for 3D printers as well as CNC mills. Or use a sender you are comfortable with already.
Features: Core XY, sensor-less homing, integrated camera, touch screen, pi, 32-bit controller, fast, quiet, beautiful prints. 300 x 300 x any build volume. Just change out the Z lead screws, rods, and four pillars. It can easily be adapted to sensored homing, which I have done in a couple of cases.
This printer is designed to be rigid and strong first, light and fast second, simple and elegant third. Most heavier printers have weight in areas that do not contribute to the rigidity of the XY axes, which is where it really matters most.
Total BOM around $750 USD.
Build time around 6 hours.

Reason for this BuildAfter working with and being dissatisfied with commercial printers for several years, I had developed my own software stack, including slicer. The next natural step was to design and build my own printer.
