@phaedrux said in G-Code syntax highlighting for modal file editing windows:

If I'm working on a larger macro I'll start writing it in notepad++ on windows or Atom on OSX which both have syntax highlighting. Then copy and paste it into the DWC.

I think with notepad++ you could even connect to the duet over FTP and work on your config files that way.

+1 for notepad++ It does work well.
