One of those ideas is to machine a wooden gear wheel using the gear generator extension in inkscape.

There are a few more approaches I can try with this software before I ignore it for the rest of my life. This contour could then be used in a subroutine to cut out decorative shapes etc. It is not very intuitive and the G-Code it produced was very basic and completely limited in options.īut if you know the basics of writing your own G-Code it can be useful for generating lines and arc codes for a complex freeform or artistic contour. It is definitely not a great solution for generating G-Code for your hobby cnc machine. I have spent my working life as a machinist in an industrial environment, so my initial thoughts about this software were not very positive.

The final result was very underwhelming but it proved the process worked and I had an understanding of how to produce G-Code using Inkscape. Using a pointed tool to pick up the corner of the stock Make sure you are saving the datum positions to the same offset position that you put in the header of your program. You can read my posts on setting your datums and tool length compensation if you need more information on these topics.įor setting my datums I just used a pointed tool positioned over the corner of the stock.

Set up the stock on your machine, pick up the bottom left hand corner for your X and Y datum offsets and set the top as your Z axis datum zero. Now you can upload the G-Code to your machine control software. To change the Z axis depths I used the replace command in wordpad to change them all at once. (changed the Z axis depth to what I want) Read the notes in the brackets to see what I changed.

Here are the first few lines of the program with my header pasted in and a few minor modifications. I am going to paste in the header and footer from my article ‘ G-Code programming for Dummies’ overwriting the ones created by inkscape. So what we need to do is add a proper header and footer.Īlso note that the Z axis depth is at zero all through the program, this is not what I wanted but is very easy to change. To add your own header create file “header” in the output dir.) I have copied and pasted the first few lines of G-Code that Inkscape produced for my small bat shape below.Īs you can see the header is very minimal and the first move is a rapid move down to Z axis zero*. Udemy have a good selection to choose from including the one in the link below which I can recommend. The first task to accomplish is to get familiar with inkscape, you could try and figure it out yourself, but I would highly recommend a dedicated course.

The words it uses to explain the processes bear no resemblance to any ‘proper’ cnc terminology.Īlso it only produces the code for the paths you draw, some additional G-code will be needed to create a proper functioning program, more on this later. Inkscapes ability as cad cam software is very limited though, the G-code function is an extra add on extension and not the software’s main purpose. It is a vector graphics program that allows you to draw freeform shapes which can then be converted to G-code using the ‘gcode tools’ extension.

This is where the free software “ inkscape” comes in. Many of you may just want to only do craft projects, it can be really enjoyable and is actually pretty easy once you have learnt the basic steps to follow. Starting with simple decorative craft projects can be an easier way to learn the basics of cnc machining.Īfter reading this inkscape G Code tutorial and using this to learn the basics, then you will be more able to progress to more complex and dimensionally accurate projects. Getting started with a Cnc mill or router can be overwhelming, there are many aspects you will need to grasp and learn to apply.
