For about a month I've been working on a SVG parser, which translates the SVG primitves to gcode, for the use with 3d printer. I started developing the Pigaso so I can easly plot PCBs with my 3D printer. Unfortunately for me, there wasn't any application, which would easily enable me to generate gcode from SVG image, or any image in that matter. So I though of making my own application to do just that. My main goal, is to develop a converted which is easy to use, and specialized for generating gcode, no hacking required. Continue reading for a demonstration.
As of now the application has the following features:
- Nearly all primitves of SVG can be drawn
- Transformations like scale, rotate, translate, matrix have been implemented
- GUI for rearrenging the object on the platform
- Recursive best effort longest path searching algorithm
There are still many features I would like to implement and I belive are quite mandatory for succesful project:
- Support line width, could be viewed as filling algorithm
- Automatic line invisibility test (detect where lines shouldn't be visible
- Scaling of the image
- Construct gcode from not only vector graphics images, but also from rastra, like JPEG, GIF, PNG.
- Improved longest path algorithm, for example use djekstra algorithm to find the longest path
- Construct a new algorithm to detect the shortest path between multiple elements
- Support of multiple pictures in one workspace
The application is written in C++ with Qt framework, which enables it to be compiled basically on any OS available. So no worries, I won't be discriminating against linux or mac users.
Soon I'll publish the projects source in one of the open source version control systems, like sourceforge or github. Until then you can enjoy the video of the Pigaso generated gcode in action:
