All my projects & progress are available at marginallyclever.com. This version of the Delta3 is complete. I have mounted it upside down in a box and added a pen to make it a plotter. I could add a dremel to make it a 3-axis CNC or a reprap nozzle to make it a 3d printer. It has fewer parts than most 3-axis CNC and can be very accurate. I have deprecated this project and now offer a newer version with better, affordable parts on my website.
