Gerber file format from FreePCB

Hi,

When I generate the CAM files from freepcb, the files end with a .grb extension. When I upload those files, BatchPCB tells me that they only accept the file formats:

  • TopCopper - “.gtl” , “.cmp”, “.top”

  • BottomCopper - “.gbl”, “.sol”, “.bot”

  • TopSolderMask - “.gts”, “.stc”, “.smt”, “.stoptop”, “.tsm”

  • BottomSolderMask - “.gbs”, “.sts”, “.smb”, “.stopbot”, “.bsm”

  • TopSilk - “.gto”, “.plc”, “.sst”, “.positop”, “.leg”, “.slk”

  • BottomSilk - “.gbo”, “.pls”, “.ssb”, “.posibot”, “.bsk”

  • Drill - “.drl”, “.txt”, “.tap”, “.drill”, “.gdd”, “.drd”, “.cnc”, “.exl”

  • KeepOut - “.gko”

  • MiddleCopper1 - “.g2”

  • MiddleCopper2 - “.g3”

  • BottomStencil - “.gbp”

  • TopStencil - “.gtp”

  • Outline - “.outline”, “.oln”

Is there a way for freepcb to generate those or for me to convert the .grb to the accepted formats?

Thanks in advance!

I had no idea on your direct question. However page 69 of your manual does not seem to show a way.

But to address the underlying problem, you should be able to use your operating system to rename files. You could automate that with a batch file (command file). It looks as if you are using Windows, so it should be fairly easy.

Agree - just re-name the files!
