Often looks like a node without a black border. Duplicate Nodes: Most common error that effects importing into CAD is two nodes on top of each other.Additional nodes will slow down CAD and CAM programs when generating G-Code and sometimes cause errors, so simplify the vector graphic when possible.Tracing is not perfect, only an approximation, so some editing will be required. Tracing can produce more nodes than is necessary to represent the image.Optimize Paths: Combines Bezier paths to reduce the number of nodes.Higher increases smoothing, zero is no smoothing. Smooth Corners: Controls the amount of smoothing at corners.Suppress Speckles: Excludes groups of pixels smaller than Size.Remove Background: Removes background color, leaving transparent background.Smooth: Applies a gaussian blur to image before scanning to reduce errors.Grays: Same as Colors but outputs the scans in grayscale.

Note: Black and White are colors so setting Scan to 4 will produce 2 color scans.Colors: Scans sets the number or colors/scans that are output.Example below was pulled apart to show two paths. Brightness Steps: same as brightness cutoff but divides into multiple paths.Be sure to select the vector created and ungroup to select individual scans: Object > Ungroup.Not used often for CNC unless there are different groups of paths desired.Multiple Scan will result in a group of paths, set by number of Scans, based on color or brightness.Determines thresholds based on number of colors to detect. Color Quantization: detects an edge where color changes regardless of brightness or contrast.Edge Detection: detects an edge by comparing the contrast of adjacent pixels.Brightness Cutoff: considers if a pixel should be black or white based on the threshold.Each time you click OK, a new vector path or group of paths will be created. Select the imported image and convert the raster to a vector.

Get Inkscape for free here Easy Way To Trace An Image For CNC Load Raster Image Into Inkscape: Inkscape has many tools which can be used to draw vector graphics, but it also has tools that can be used to trace raster images and convert them into vector graphics. For free software, Inkscape is very powerful and there is a large community of users posting tutorials and YouTube videos. It is very similar to Adobe Illustrator or CorelDraw but is typically missing some of the most recent tools. Inkscape is an open source (meaning it is free) vector graphic software. A vector graphic can be easily used to generate g-code. Vector graphics are best for scalable images like logos or for engineering CAD. The position of lines and edges is calculated mathematically so the image will be very accurate and independent of resolution.

They can also be defined with dimensions such that real-world objects can be represented in true scale. Because of this, they can be scaled to any size without losing quality. Vector graphics (SVG, DXF, DWG) use mathematical operations to calculate points or edges (paths) of shapes.

They are not precise enough for representing a scaled image or a real-world object. Raster images are the most common digital image and are best for photographs and images with a lot of shading. Also, if the edge of a line were to fall between two pixels, it will get averaged and appear blurry or shaded. The image will appear clearly at its intended resolution but will lose quality when scaled since pixels will be averaged. Pixel size is set by the resolution of the raster image based on the number of pixels per inch. The image is made from a fixed number of pixels, but the size of a pixel is not defined. Raster images, (JPEG, BITMAP, PNG, TIFF) are created by a grid of coloured squares, called pixels. Difference between Vector Graphics and Raster Images Not all image types are suitable for generating g-code for CNC machines. Therefore, if we want to make something on a CNC machine we first need a scaled, mathematical model of it. The programs that control a CNC machine are generated mathematically from a digital model of the object or design that is to be created. Movement of a CNC machine is controlled by programs (G-Code) which move the machine to specific positions or along specific paths.
