SolidCore CoreXY 3D Printer

SolidCore CoreXY 3D Printer Designed By Shane Hooper & Mike Fisher 3D Distributed https://3ddistributed.com/corexy-3d-printer/ https://www.thingiverse.com/thing:4307266 While the SolidCore design is still a work in progress it’s slowly but surely materializing. For now we decided to go with a simple but functional design but still have many plans that will later be adapted for additional tools and configurations. We recently moved the z-axis motors to the bottom of the printer and are setup to either use three independent driven z-axis motors or a single driven motor with the belt path connecting to three z-axis lead screws. Modular / Scalable All Metal or 3d printed Linear Rails Balanced Carriage Pull Enclosure Triple Z-Axis: Independent Driven or Shared Belt Routing With the motor and idler mounts placed on the inside corners of the frame gives us clearance to easily mount an enclosure. This configuration also eliminates any design constraints of overall length and width which maker the machine completely modular and scalable. Eventually we would like to have a spreadsheet or configuration tool that will allow you to input the current frame or linear rails that someone already owns and output length and rail options. Or if you’re aiming for a specific build area, you can input the data and it will output the frame and rail length options. The carriage and gantry are designed to be light weight and strong. We currently use c-shaped aluminum stock because it reduces machining time. The reduced machining time and minimized waste helps but it’s a compromise. That's going to change soon. We’ll probably make some changes such as reorienting the the y-axis linear rail into a vertical position similar to the RailCore but the current horizontal version will be easier to adapt an E3D Toolchanger. The top plates or motor/belt mounting plates that mount the idler pulleys have recently changed as well. The motor/belt mounting plates shown position the z-axis motors on top vs t
