We want it to be at least 10 mm away from the X and Y axes. Also, we position the object where we want it. In this example we want it to be maximum 100 mm in either axis. Therefore we scale the object such that it is as large as we want it in millimeters (click the padlock icon or hold ctrl down and drag a corner to lock proportions).

We want to have control of how large the result will be in real life. Just cut-paste it into a new one to be sure.

The object needs to be in an own layer(click the link to see how to use layers). Since the drawing of the dinosaur is a regular bitmap image we need to trace the bitmap. A dev version is also available from githubif that’s what you prefer. The gcodetools extension is now included in Inkscape’s default extension library.

Preparationsįirst we follow the guidelines on Gcodetools’ page to install the extension. The way the laser engraver interprets the G-code is that it turns on the laser when the virtual Z-axis has a negative value and off when it’s zero or positive. In this example we will generate a toolpath for our laser engraver to engrave a drawing of a dinosaur. Gcodetools’ main features according to the developer Step-by-step Tutorial (by example) It is far from perfect and poorly documented, but it does the job. You’ll need an extension (that’s what they call plugins in Inkscape) to be able generate G-code in Inkscape, and the only one that we’re aware of which is capable of doing so is Gcodetools (yes, this forum thread is the closest you’ll get an official page). However, if you’ve made a machine on your own which need some kind of motion, such as a drawing machine or a laser engraver, generating G-code in Inkscape is both quick and easy.

For that it’s too dangerous! For those kind of machines you should use more professional software, such as anything from Vectric. Using Inkscape to generate G-code is NOT recommended when operating CNC mills, lathes, cutters or anything of that sort. When generating G-code this way it’s important to know what kind of machine you’re generating G-code for and how it interprets the code. Writing G-code manually for more than a simple square would be practically suicide, so luckily we have programs which do this for us. A snippet from an actual G-code file Generating G-code in Inkscape The last block moves the machine in a straight line to position (2.2,3.3) in the XY plane with a rate of 500 mm/min. The third block moves the machine in the Z-axis to -1 with a rate of 100 mm/min. How fast this movement is done is defined in hardware. The second block makes the machine run rapidly to position (1.1,1.1,1.1) in the XYZ space from its current position. G21 defines all numerical values as millimeters. G90 is the command that defines all coordinates as absolute with an origin as a reference. The first block does two things and is kind of a very simple setup block. ExampleĪ trivial example of a couple of blocks: G90 G21 A list of the different G and M-codes can be found here and here. A complete list of all of the letters with explanations can be found here. The most important ones are arguably G (used in most movement commands), M (miscellaneous commands), X, Y and Z (the last three are used to define positions in the X,Y,Z space, absolute or incremental). These letters corresponds to different types of commands.

Everywhere you look in the code you will mostly see letters with numbers behind them. A CNC mill interpreting G-code in real-time Structure and CommandsĮach new line (called block) in the G-code can be roughly regarded as a new command. G-code has many dialects or variants, but most (or all) adhere to certain common rules. G-code is the most widely used programming language for controlling industrial machines such as mills, lathes and cutters as well as 3D-printers. As a natural continuation from last week, we’re now going to talk about such toolpaths, called G-code, and how to generate those in Inkscape. The third suggestion on why to do such a thing involved creating toolpaths for machines. In last week’s post we discussed how to create vector graphics from bitmaps in Inkscape.
