This is a small size desktop 3D printer. I have noticed most of the parts I print are small and I was looking for a second 3D printer to handle larger prints. <h1>Features</h1> <strong>Build Volume</strong> X: 100mm Y: 100mm Z: 100mm <strong>Quick and Accurate</strong> This 3D printer uses a short Bowden tube setup with a high torque extruder, allowing for quick travel moves. The belt tensioners are integrated as well as an adjustable Z endstop. <strong>Silent</strong> Trinamic's TMC2208 stepper motor drivers provide high torque and speed in ultra silent operation. <strong>Clean</strong> This 3D printer comes with cable management. All axis use drag chains for durable and clean wire guidings. <strong>Affordable</strong> Common parts are used to keep costs down. <strong>Easy to use</strong> Preconfigured Marlin firmware and Slic3r profiles make it easy to get started. <h1>Bill of Material</h1> Download the latest BOM file with Aliexpress links for a complete list of required components. <strong>Electronics</strong> - Arduino 2560 + RAMPS 1.4 - 1x Radial Fan 5010 12V/24V - 1x Axial Fan 3010 12V - 3x Stepper Motor Driver Board TMC2208 - 1x Stepper Motor Driver Board A4988 - 1x LCD Adapter - 1x MKS Mini 12864 LCD with cable ties - Cable Ties <strong>Print Surface</strong> * Insulation Material underneath (wind shield cover, PU foam, cardboard, etc.) * Print Surface to your liking (PEI, BuildTak, PVA glue) <h1>Configuration</h1> <strong>Reference Voltages of Stepper Drivers</strong> - X: Trinamic TMC2208: 0.8V - Y: Trinamic TMC2208: 0.8V - Z: Trinamic TMC2208: 0.8V - E: Allegro A4988: 0.65V <strong>Firmware</strong> Download the latest configuration.h and configuration_adv.h for Marlin 1.1.9 in the Files Section. <strong>Assembly</strong> Find a 3D PDF in the download section to arrange the parts. Use a compatible reader, such as Adobe Reader. Filament path: Mount the bowden strain relief to the 2040 Z extrusion, above the ramps board for better print quality. <h1>Known Issues</h1> - Display (SD-Card) Circuit Board needs to be cut or use some rubber feets <h1>Changelog</h1> 2019/01/12 added missing chain mount for Z axis 2019/02/10 improved hotend heatsink airflow, cleaned up BOM 2019/07/28 fixed aluminum profile type 2019/12/20 added bowden filament strain relief
