drill2gbr.exe can also run from the command line for batch processing. It is necessary to have determined the parameters of both the drill file and target Gerber file ahead of time in order to get the expected results.
You will need to know parameters such as Gerber and drill units, gerber and drill format, zero inclusion/suppression, drill sizes, etc. After the conversion, we recommend loading the resulting Gerber file together with one of the other layers and make sure they are aligned. If not, you will probably need to change one or more of the settings on the command line.
Here are the options available on the drill2gbr.exe command line:
