Самосбор CroXY 3D Printer

Major features of CroXY 3030 and 3060 frame members for stiffness and ease of assembly Crossed rail gantry design with 4 motors driving 9mm or 12mm XY belts Triple SFU1204 ball screw driven Z for automatic bed levelling Linear Rails are all MGN12H Fully Enclosed, with option for 20mm of insulation. Printer functions fully without panels for materials that do not require insulation. Bed is 6mm Mic6 and is kinematically mounted with Kelvin kinematic joints preloaded by magnets. Thicker beds are possible. Hemera Direct Drive E3D extruder toolhead Magnetically coupled switch based probe picked up from a dock for super accurate bed probing. Dedicated area for nozzle purge and wipe. Z Towers are built on a single 3060 extrusion making ball screw and rail alignment extremely simple. Duet2 or Duet3 electronics with Reprap firmware 2 or 3. Klipper support is planned Built in optional drawer for tools and or a spool that feeds the extruder. Breakaway XY rails to prevent bending them in the case of a head crash. Feet with sorbothane vibration isolation. Footprint comparable to other printers of same bed size. Design is for 250x250x250 nominal size. Up to 350x350x500 should be easy. MGN15 Gantry mod in development will enable build sizes up to 500x500x500. Minimal printed parts. Most are designed to be easily machinable by aluminum for even more stiffness. Aluminum Z lifters are already designed. Aluminum toolhead, XY motor base plates and XY carriages are also in development.
