How to create the G-code files from any gerber file (using PCBMill software) necessary to create a PCB with 3Drag, by milling. To create a PCB with 3Drag, by milling, you need the G-Code files for the tracks patterning  and for the holes pertaining to the printed circuit board itself. In this section we describe how to obtain these G-Code files, starting with a gerber file created by using any design software for PCBs: for the conversion we use the free software PCBMill  (supplied by CNCdrive company). This software is very simple and intuitive and allows to obtain G-Code format files that can be imported without any problem in Repetier Host . The creation of the printed circuit provides the use of a chisel to make the incision of the tracks and of a drill bit with the suitable diameter for drilling. Both are to be mounted in the electric mandrel. - The first procedure is to download the software PCBMill (PCB milling software tool) from the downloads of [...]
