An interesting piece of software I ran across in Fusion360 help forums.

NC Corrector is an editor for g-code. It has a visualizer and the ability to “play” the g-code and watch the operations.
There are lots of editors out there - I use Notepad++ frequently. The reason I mention NC Corrector is that it has a feature I’ve been looking for - g-code to DFX conversion. It allows you to export gcode as a DFX. I found one or two programs that sort of do it, but this one seems to work pretty well. Most of the time you’ll have the design you generated the gcode from, but in the cases where you don’t - this will let you create the design from the g-code. I’ve had a few cases of this, and it’s useful to me.
Another interesting feature that I like is you can click in the visualizer and it will jump to the line of code that generates that line or arc. I can see where that’s useful in a large complex gcode file especially if you are trying to track down a cut issue.
(I wish you could do that in Firecontrol and click run from here)…
Another tool for the toolbelt…
