This library's intended purpose is to laser-cut svg images. If others think my workaround is a good solution, then the same change could be applied to similar lines in the code.Svg to Gcode - Flamma project The definitive NPM module to construct gcode from svg files.ĭon't feel like coding? Use the Inkscape extension. This only solves the problem when the cutting order 'subpath by subpath' was selected when running the extension. '''+++ curves_ =, ] for subcurve in curve] + curves_''' '''- curves_ +=, ] for subcurve in curve]''' I changed that line to add each curve to the beginning of the list instead of the end, effectively reversing the list. In line 3952 in gcodetools.py, the extension saves the letters to a temporary list. However, I have been able to make a workaround. I have not been able to find why those paths are in the wrong order when the Paths to Gcode extension handles them.

At least, that's what I see using the XML editor, which shows the path of the first letter at the top of the list. The paths for the text are in the correct order in Inkscape after the Hershey Text extension has transformed the text on the canvas to paths. If the order of the paths in the SVG are followed, then they are drawn line for line and in the right direction. It arranges the curves in vertical columns, so detached from the rest of the letters and lines. Someone suggested running Arrange > Restack, but this does not work for me. The extension should output gcode for paths in the order that they appear in the SVG. This is a problem because I want the plotter to simulate human writing and because I have a whiteboard eraser attached under my pen, so if the text is written from bottom to top, then the machine immediately erases the text it has just written :-) What should have happened? So it starts writing a paragraph from the bottom right, writes lines right to left and finishes on the top left. The Gcode which the 'Paths to Gcode' extension outputs makes my pen plotter write in the reversed direction.

See the resulting gcode in a Gcode simulator like (you need to remove the spaces after the Z's, X's and Y's for the file to show there).
