Some time ago the DRCbot stopped accepting ‘floating files’ but what was not made clear was that that means that the files in the .zip must all now have the same name. KiCAD helpfully adds layer names to the gerber output files so you don’t have to remember the extensions. However, this means you need to rename all the files before you submit them. Thus, I made a small batch file that will rename your files and automatically zip them up. This is the first time I have written something like this so feel free to let me know if there would be a better way to do it.
