The development of additive manufacturing technology encourages increased accuracy and efficiency in 3D printing processes. This research aims to design and implement an automatic leveling system based on XYZ-axis sensors on a Double Vertical Frame 3D printer to improve print accuracy. The system utilizes a CR Touch sensor to detect unevenness on the print bed, which is then corrected automatically by adjusting the nozzle height via Marlin firmware and slicing software G-code integration. Testing was conducted with 9, 16, and 25 leveling points. The results showed that the system could correct unevenness with a tolerance of ±0.5 mm and an average print deviation of less than 2%. The auto-leveling process duration averaged under 1.5 minutes. This innovation not only reduces manual calibration errors but also enhances printing quality and consistency, making it suitable for educational and industrial applications.
