== Overview ==
My Ender 3 is a heavily modified original V1 model, upgraded for high-speed, high-quality printing with modular capabilities in mind. It’s equipped with a BIGTREETECH SKR Mini E3 V3.0 mainboard, which offers quiet TMC2209 stepper drivers and Klipper compatibility thanks to its 32-bit architecture. I’ve replaced the stock extruder with a Sprite Pro direct-drive system, enabling better control over flexible filaments and high-temperature materials. The printer is controlled via a Raspberry Pi 4 running Klipper, Moonraker, Mainsail (for the web interface), and KlipperScreen, which outputs to a BIGTREETECH PITFT50 V2.1 5" touchscreen for local access.

My setup is optimized for manual tuning first—focusing on filament flow rate and pressure advance—before implementing accelerometer-based input shaping. The long-term goal is to rival the speed and quality of printers like the Bambu A1 Mini while maintaining full control over the system. I’m also developing a modular quick-change toolhead system that allows me to swap between the 3D print head, a small CNC spindle for aluminum machining, a Rack Robotics EDM head, and a laser engraver. Each toolhead will have dedicated connectors for clean, tool-specific wiring. The frame is stabilized with a foam base and weighted platform to reduce vibration during fast movements, further improving print consistency.
