GCodeDateien

GCodeDateien, often referred to as G-code files, are plain text files that contain instructions for controlling CNC (Computer Numerical Control) machines. These machines include 3D printers, laser cutters, and milling machines. G-code is a programming language that tells the machine exactly where to move, how fast to move, and what actions to perform, such as extruding material or activating a spindle.

The most common type of G-code used in 3D printing is generated by slicing software. Slicers take a 3D model (typically in STL format) and convert it into a series of thin layers. For each layer, the slicer generates the G-code commands that instruct the 3D printer to trace the outline of that layer, fill it in, and then move up to the next layer. This process is repeated until the entire object is printed.

G-code commands are typically made up of one or more lines, with each line representing a specific instruction. Common commands include G0 (rapid linear move), G1 (linear move at a specified feed rate), M104 (set hotend temperature without waiting), M109 (set hotend temperature and wait), and M140 (set bed temperature without waiting). These commands are often accompanied by coordinates (X, Y, Z) and other parameters like feed rate (F) and extrusion amount (E).

Understanding G-code can be beneficial for advanced users who want to fine-tune their prints, troubleshoot issues, or even manually control their machines. While most users interact with G-code indirectly through slicing software, the underlying code is the direct language of digital fabrication.
