ofxGCodePlotter

ofxGCodePlotter is an "ofPath to GCode" converter. It is currently very alpha and misses a lot of functionality.

ofxGCodePlotter will _never_ be a GCode library. I personally only use it for converting ofPaths in 2D into one layer GCode.

Usage

Install the addon like any other openFrameworks addon. ofxGCodePlotter uses ofxCubicBezierToBiarc to convert cubic bezier curves to arcs - so that addon will also be pulled in.

Next copy the example config file and adjust the settings as needed.

Then create an instance of ofxGCodePlotter like so: ofxGCodePlotter gcode = ofxGCodePlotter('path/to/config', width, height);.

Feed it with a vector of ofPaths: vector<GCodePath> paths = gcode.generate(shapes);

Print to the console: ``gcode.print(paths);

Limitations / Roadmap

Shortest path Print filled paths (hatching). Cut paths under a filled path. Do not print off canvas content. Inject a tool.

• Feed rate.
