The Dark project was the natural development of the Darkcut.
It can transform arcs, circles and lines in two dimensions to a language known as G Code, a widely known language to the computer numerical control applications. Since I prefer to use Linux for development, this project was done for a Linux machine, using common tools.
It is also under current use in the company that possesses the DarkCut machine, Mastor, Lda, that uses Linux OS.
What can it do ?
It can handle a DXF file, with one layer of information, containing only circles, arcs and lines (all the necessary do draw anything). After, it parses the file, looking for connected objects and constructs the G Code output file. The G Code only uses a small amount of codes, but all the necessary to create a tool path in 2D, for cutting.
The source for the DXF file can be any CAD program. In Linux the most known software is QCad, it is a good software and frequent updated versions are avaiable. In the following example, the G Code presented on the right was generated from the DXF file obtained from the drawing on the left.
It was obtained setting the feedrate to 700 mm/min, delay 40 sec between pieces and 0.3 seconds for initial drill.
This project is property of the Mastor company.
