Open-Source CoreXY 3D Printer
“I wanted to build my own Voron, so I made my own design. This is my take on a CoreXY printer that follows the same mechanical principles as the Voron.”
MY-CoreXY 3D Printer
The MY-CoreXY-3D-Printer is an open-source CoreXY 3D printer, designed for high-speed and high-precision printing. Inspired by the Voron series, this project is ideal for makers, engineers, and DIY enthusiasts looking for a reliable and customizable 3D printer.
