I've added my script to the Wiki, http://wiki.linuxcnc.org/cgi-bin/wiki.pl?LinesToArcs
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. It's slow, but has been reliable over the last couple of months.

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? I want to use this to simplify the output of the 3d printer software Slic3r. It only generates line segments which slows down my router. Most of my shapes have circle shapes, so it would be nice to use G2/G3. I've tried a trial version of a program I found on the 'net, but it didn't work because there are A axis moves on each line (A = extruder).
