If you own a 3D printer, CNC router, or basically anything else that makes coordinated movements with a bunch of stepper motors, chances are good that it speaks G-code. Do you?
If you were a CNC machinist back in the 1980’s, chances are very good that you’d be fluent in the language, and maybe even a couple different machines’ specialized dialects. But higher level abstractions pretty quickly took over the CAM landscape, and knowing how to navigate GUIs and do CAD became more relevant than knowing how to move the machine around by typing.
Reprap Darwin: it was horrible, but it was awesome.
Strangely enough, I learned G-code in 2010, as the RepRap Darwin that my hackerspace needed some human wranglers. If you want to print out a 3D design today, you have a wealth of convenient slicers that’ll turn abstract geometry into G-code, but back in the day, all we had was a mess of Python scripts. Given the state of things, it was worth learning a little G-code, because even if you just wanted to print something out, it was far from plug-and-play.
For instance, it was far easier to just edit the M104 value than to change the temperature and re-slice the whole thing, which could take an appreciable amount of time back then. Honestly, we were all working on the printers as much as we were printing. Knowing how to whip up some quick bed-levelling test scripts and/or demo objects in G-code was just pla ..
