X-Y-Z Coordinate System The X-Y-Z coordinate system is a 3D Cartesian grid that defines the position of the print head, build platform, and model geometry in three-dimensional space. It provides precise motion control, layer placement, and dimensional accuracy. X represents horizontal movement, Y represents depth, and Z represents vertical height. Proper homing, offset calibration, and motion planning ensure accurate positioning and alignment. Advanced printers use closed-loop control and optical encoders for high-resolution accuracy. The X-Y-Z coordinate system is fundamental for toolpath generation, model slicing, and 3D printing precision. |
