svg2gcode

Convert any SVG 1.1 path to gcode for a pen plotter, laser engraver, etc.

TODO

• Support all path variants
• Support group and path transforms
• Biarc interpolation (G2/G3 instead of many G1)
• Px, pc, in to mm
• Configurable DPI for px/pc to mm
• Sort paths by distance to reduce G0 distances

Known bugs & whether fixed

• Smooth curves should not use the control point when the previous curve is not of the same type (quadratic -> smooth cubic, cubic -> smooth quadratic)
• Image coordinates mirrored in the y-axis because SVGs uses upper left corner as (0,0) while GCode uses lower left as (0,0)
• Close path command connects back to (0.0, 0.0) instead of the last move
• Ellipse paths are dubious -- large_arc, sweep may need to be inverted
