CoreXY 3D printer from scratch

engineered and fabricated a bespoke CoreXY 3D printer, all from scratch, by synthesizing Voron influenced kinematics with a custom Z-axis assembly. This triple lead screw bed system, inspired by the Bambu Lab X1C, utilizes a single motor to maintain synchronization across the build plate.

The machine is powered by a BigTreeTech SKR Mini E3 V3 and a Raspberry Pi 4 running Klipper firmware. While the printer reliably sustains speeds of 500mm/s, the current performance ceiling is dictated by the hotend's maximum volumetric flow rate rather than mechanical instability.

This project served as a deep dive into systems integration and the principles of kinematic constraint. I successfully optimized the design by eliminating parasitic degrees of freedom and managing tolerance stackup, ensuring all components are properly constrained to prevent unwanted deflection during high acceleration moves.
