I am interested in having a few of your boards produced. Mainly the expansion and serial boards. I typically use OSHpark to create boards. When I upload your gerber files they are not accepted because of standard naming. I renamed the layers changing the extension names, but the board outline file is missing.
Question... What software did you use to generate the gerbers? That may help me understand what I need to do to get the filenames to match what my board maker is expecting.
