There are further options with the drop down menu. This will machine your chosen profile offsetting the tool to the inside. I will show this in my demonstration later in this article. This can be combined with other profile selections inside a larger area.
The pocket option will machine an area inside your selected profile.
The create operation option is for choosing your machining strategy. If you use different software you may need to change this to get accurate sizes for your G Code. It should load as 96 by default as this is what Inkscape uses. This option box allows you to set your pixels per inch. metric3mm.jscut, which could represent metric units and a 3mm endmill. Just change the word ‘settings’ to your new name, e.g. A box will appear with the file name ‘settings.jscut’. To save each setting just make your changes and click ‘save settings’. This means you can quickly change all the settings to match the feeds and depths of cut etc, for all the different tools you own. So it makes sense to save multiple setting files for all the different sizes of tools you own. One of JSCut’s shortcomings is that only one tool can be used for your loaded SVG file. JSCut will allow you to change these settings and to save your changes so you can load them when needed. When you open JSCut in your browser, it loads with its default settings. Testing and trying different operations until you are satisfied with the result is a typical process you will have to follow. With this in mind, you sometimes have to ‘trick’ the software to do what you want. Inkscape does include an addon extension that can create G Code but it is really clumsy and unreliable and I do not recommend it. Inkscape is a high quality downloadable software that fills this need perfectly.
To create your own SVG files you need SVG software. SVG stands for ‘scalable vector graphics’, a full explanation can be found on wikipedia. One of the best file formats to create free cnc patterns for your projects are SVG files. The examples in this article will be aimed at basic cnc machines like the 3018 engraver, as this is the type of cnc router that people start with in this hobby.įollow the link for a complete 3018 unboxing review and setup tutorial of this type of machine on this website. This will create any basic 2D shapes for your cnc router or mill. I will show the process of using a free G code converter which uses SVG files. If you can relate to this problem, just keep reading this article, it will help you get started. Just learning what processes you need to go through to get to a finished project can be a lot to take in at first. One of the hardest and most frustrating challenges for a new cnc hobbyist is converting an SVG to G Code for your own cnc projects.
