This function creates path to engrave letters or any shape with sharp angles.

Cutter's depth as a function of radius is defined by the tool.

Depth may be any Python expression. For instance:

cone....(45 degrees)......................: w

cone....(height/diameter=10/3)..: 10*w/3

sphere..(radius r)...........................: math.sqrt(max(0,r**2-w**2))

Gcodetools plug-in: converts paths to Gcode (using circular interpolation), makes offset paths and engraves sharp corners using cone cutters.

This plug-in calculates Gcode for paths using circular interpolation or linear motion when needed.
