I’ve been using this program for years… I’m sure to most here, it’s old news, but I’m sure some may have never heard of it.
If you haven’t , get Notepad++. It’s a great text editor and it supports many different coding languages.
you can download and import the gcode syntax also.
One thing I like about it, is I can do some quick notes on a tab and close the program without saving. When I open it back up, the notes are still there.
More often than not I use the VisVim module so I can have my vi keybindings in Visual Studio (primarily targeting Android drivers, no less!). In which case, I think my street cred just evaporated.
