The first thing to understand is the difference between a raster file and a vector file. Vector files are easy and ready to go but raster files may take a little work to make them compatible with the CNC software.` The Difference Between Vector Files and Raster Files.

Many CAD software programs can import an image and help you edit the result. Many people buy images off of the internet to use as a CNC pattern.
One way to cheat this lack of talent is to use an existing image file. After several attempts, it becomes just a bit frustrating that my artistic skills are not as good as my imagination makes me believe they are. The method I used is the same for VCarve, Aspire, and Cut 2D.Many times I have seen a project that I would like to replicate but just could not get the scale and curves right. In the video linked below, I demonstrate one way to check for and eliminate unnecessary points from vectors imported from a DXF file, into VCarve Pro. This is especially true if it only take a few seconds to do. I don’t think anyone would argue that if you can improve your daily output from 5 per day to 6, and achieve a finer finish straight off the table in the process, it’s not worth taking the time to do. But those seconds or minutes can add up if you’re cutting a large piece of material, or if you have several copies of the same project to cut. How much shorter of a machining time? Well, there are lots of variables – it may only be a few seconds or minutes. This can result in quicker calculating times, smaller g-code files, a smoother curved cut, and even shorter machining times. By simply applying curves to the vectors, and having those curves replace the imported vectors, we can make a dramatic reduction in the number of points the software has to use to calculate our toolpaths. It’s generally accepted that the smaller the number of points the software has to calculate, the better your finished project will turn out. This will result in a huge number of calculations, bloated g-code files, and could lead to faceted curves rather than smooth curves.
If these vectors were left as is, the VCarve software would have to calculate the toolpaths necessary to cut the project by calculating from each individual point to the next point.

That resulted in turning the long curves to a series of straight lines – a huge series of straight lines. In the example file I used in this video, the program the vectors were drawn in converted all of the vectors to polylines. Why is it a good idea to remove these extra points? There are several reasons: faster toolpath calculation times, fewer lines of g-code and smaller g-code files, smoother cuts on the final product, and more. This will almost always result in the need to reduce the number of unnecessary points in these vectors. In any case, we need to get in and check them.Īfter importing vectors, whether they’re from a DXF file or any other source, it’s usually a good idea to immediately join them, and then go into Node Editing Mode to see how many points make up these vectors. This is done to reduce file size and eliminate software conflicts. Additionally, sometimes the export process within the creator’s program will change the type of vectors being exported to polylines, no matter what type of vector the creator used. It may or may not be readily apparent as to which type of vector the file’s creator used when they drew the vectors. All vectors are based on one of these three types. Among these basics are the numbers of points in the vectors and what type of vectors they are. Īs I’ve mentioned before in previous posts, there are three types of vectors: arcs, curves, and lines. While there’s nothing inherently wrong with that, it can lead to side issues if some of the basics aren’t addressed. One of the side effects of importing vectors from a separate CAD or graphics program is that you’re importing those vectors as drawn by the file’s creator.
