The most widely used language for programming CAM machines is G-Code. G-Code is also known as the G programming language. This language was developed at MIT in the 1950s. Since then, various organizations have developed versions of this programming language. Different countries have different standards for this language. The name comes from the fact that many instructions in this code begin with the letter G.

This letter is used to convey travel or route commands to the machine. The commands go, in the true sense of the word, from A (absolute or incremental position around the X axis rotating around X) to Z (absolute or incremental in the direction of the Z axis). Commands with the prefix M (many) transmit other instructions to the machine. The coolant on / off is an example of an M command.

If you want a more comprehensive list of G code commands, there is a table on Wikipedia. You can write this G-code in any editor of your choice. But when it comes to more complex things, you usually won't do this kind of low-level encoding by hand. #ADDING FONTS TO INKSCAPE SOFTWARE#īut what about when you want to use a plotter or laser engraver? Other software for writing G code When it comes to 3D printing, the cutter writes the G-code for you. Then you will need a program to do this work for you. Sure, some CAD programs can write G-Code.

Here are some other open source solutions for this: dxf2gcode, normally a command line tool but has a GUI implemented in Python dmap2gcode, you can import raster graphics and convert them Millcrum, a browser-based tool LinuxCNC, can import raster graphics and convert them to G code TrueTypeTracer or F-Engrave if you want to engrave fonts As you can see, there is no problem finding a tool to do this.īut not all open source CAD programs can do this. What I don't like is the use of raster graphics. I use a CNC machine because it works more precisely than I could do by hand. Using raster graphics and plotting them to make a path for G-Code is no longer accurate. I find using vector graphics, which has paths anyway, is much more accurate. When it comes to vector graphics, there's no getting around Inkscape at least not if you use Linux. But they are nowhere near the capacity that Inkscape has. So the question is: 'Can Inkscape be used to create G-Code?' And the answer is yes! 'Since version 0.91, Inkscape has been bundled with an extension called GCode Tools.
