You need to get from the SVG file I’ve posted above to instructions for your CNC machine to run. There are several options for this process (called CAM). If you own a Shapeoko and have access to Easel, you can use the SVG import feature to bring in the file. You can also use MakerCAM if you don’t have access to Easel.
If you are using Easel, this should already be mostly done already. The thin lines are Outline paths, meaning they will be cut all the way through the material. Select all of these lines and check “Outside” under the Fill / Outline toggle. This will tell the machine to cut along the outside of those lines, making sure the box fits snuggly together.
If you are using MakerCAM, individually select all the notched panels and set them to be profiles. Then select the thin rectangles and set them as pockets, to half the depth of your material. This makes the lid section
If you are using Easel, you can simply send it to your Shapeoko at this point.
If you are using MakerCAM, double check your feed rates and depth per pass rates, and export the .nc file. Then boot up Universal Gcode Sender (or your preferred gcode sender) and start sending that file to your machine.
