Deriving a Configuration from GCodeBaseĬreate a file with a unique name of your choice. One such example configuration for outputting G-Code in Millimeters is defined in file GCodeMM.js and available in the user interface as the configuration called G-Code (G41/G42). This is the case for most machine controllers. G1 X10 Y20 for a linear movement), the configuration can be derived from the existing configuration for G-Code called GCodeBase, which is defined in file GCodeBase.js. If the desired output is a G-Code dialect (e.g. This text stream is exposed through the member variable this.stream. CamExporterV2 offers a text stream ( QTextStream) to write to the exported file. CamExporterV2 also takes care of the various features of QCAD/CAM, for example tool radius compensation, lead in / lead out, cutting inner contours before outer contours, path optimization, etc.ĬamExporterV2 does not output anything by itself, but would produce an empty file on its own. Various methods in CamExporterV2 are called to export the file header, the various entities in the CAD drawing and the footer. CamExporterV2 defines the basic structure of CAM exporter configuration classes. The ECMAScript class must derive directly or indirectly from class CamExporterV2, which is defined by QCAD/CAM.

If the script file is called MyGCode.js, the class defined inside the script must be called MyGCode.

Basic StructureĮach configuration file contains an ECMAScript class with the same name as the script file. New format implementations can be added to the same location. All available configurations are stored inside the directory postprocessors. Each supported CAM format is defined in a configuration file (or 'postprocessor') which is an ECMAScript (JavaScript) file that implements the format details. These formats can be dialects of G-Code or other, completely different formats. QCAD/CAM can export CAD drawings to various formats used in CAM (computer-aided manufacturing).
