Convert an image into gcode for laser engraving
- bitmap vectorization using
potrace - svg to canvas conversion using
canvg - canvas to gcode using a patched version of
gcanvaswhich features:- fixed
clipperinset for paths with holes - updated gcode commands to replace Z-axis movement with laser on/off commands
- path simplification/cleaning
- use standard units per minutes instead of inverse time mode
- fixed
- final gcode path optimisation using a simple algorithm to minimise travel between points (can decrease travel time up to 90%)
simulation:
node index.js | gsim
export:
node index.js > image.gcode
- code cleaning
- create a cli tool
- handle more options
- better control on converted gcode scale
