Cura and arc-overhang script

[Almazick]

I just tried your script and I'm getting an error using Cura. I don't know if I'm doing something wrong or not. I'm using Python 3.9.2

root@Debian:/mnt/usb# python3 ./arc-overhang.py ./test1.gcode
Traceback (most recent call last):

This script is currently only compatible with gcode created by PrusaSlicer

[nicolai-wachenschwan]

PrusaSlicer puts the used config at the end of the file and uses special keywords in the gcode, the script listens for.
Porting the script to cura requires changing all this specific code, you can try this if you want.

Porting this script to Cura is not so easy. Reading the Cura parameter is not a big issue. But as Cura doesn't tag the Overhang code as Prusa do it will be difficult to analyse and separate the code to convert the overhang areas in circular interpolation.
