I just hacked the code. The original comments say it was based on the
"Douglas-Peucker simplification", but because of the way it subdivided the
gcode commands, it would end up

great job, Frank!
this might be worth considering a canon optimisation stage in the interpreter
(that'd be near the comment-free wastelands of the NCD code ;)

Wow Frank!
I think I will use your code in a Rhino script later on. :)

Thank you Frank. Since I don't have a 3d printer, and likely won't have in
my remaining time, its of limited use to me, although I would expect
I've added my script to the Wiki,

It will take a gcode file (only tested with Slic3r output) and convert the
many short line segments back to arcs. It can make a huge difference to
print speed and file size if there are lots of arcs.

Since LinuxCNC does NURBS and b-splines, why not fit splines while
you're at it.

Does anyone know of a script that converts G1 line segments into G2/G3
curves? In the src tree I found author.py which has an implementation of
the Douglas-Peucker simplification algorithm, but I can't see where it is
used. Is there a script anywhere that uses it?
