Codeg

As a codeg newbie, I found it easy to compile and run codeg on my Gentoo Linux system. I did spot a minor bug in the documentation. In the README file the recommended test command is:

./codeg --in test_files/complex.dxf --out gcode.nc --quad 1 --feed 1 --x-lead .25

but --x-lead is no longer recognised as a parameter.

I'm not quite clear on the way tool offsetting is done. The --tool option sets the tool number, and the --comp option sets compensation to relate to a tool number, but how does the program determine the tool radius?

The built-in plotter plot.pl fails for me, with the error message:

perl: magick/cache.c:874: AcquireNexusPixels: Assertion `nexus_info->length == (MagickSizeType) ((size_t) nexus_info->length)' failed.
Aborted

I think this is probably an imagemagick bug, not a codeg bug, but at present I'm unable to confirm the codeg output.
