The Quantum ORD Bot is out. It is 3D printer platform made from MakerSlide linear bearing. It is extremely ridged and very easy to build. The design can easily be scaled in X,Y and/or Z by simply changing the Makerslide lengths plus belt and leadscrew lengths. This is the mini or 'Quantum' version. The parts other than MakerSlide are either off the shelf standard items or easily fabricate with a laser cutter, 3D printer or CNC router. The price is around 500$.
