The last step in cad stag save files to .DXF file
I have made GCOD by using Aspire 9.5 This softwre provides a powerful but intuitive software solution for creating and cutting parts on a CNC router. There are tools for 2D design and calculation of 2D toolpaths such as Profiling .
The vedio below explain how it works
This tool path milling are storage to flash memory and plug it in cnc controller that shown in figur bellow
