CAM Export (Producing Gerber Files)

Computer Aided Manufacturing (CAM) files, also known as Gerbers or Gerber files, are the standard format for describing your board design to a board house who will manufacture it.  Since Fritzing does not yet automate the task of creating these files, you will need to use the standard Eagle tools to manually produce the files.
In case you need it, here's a list of manufacturers.

1. Open your board in the Eagle PCB editor and make sure that everything is as you want it (parts in the right place, all connections wired, etc.).
   
   
   
2. Select File > CAM Processor. The Eagle CAM Processor window should open.
   

   

   
   
3. From the CAM Processor window, select  File > Open > Job.... The Job Selection file navigation dialog should open.
   

   

   
   
4. Navigate to the the Fritzing install directory, then to the eagle\cam\ folder, choose the fritzing_gerbers.cam file and click Open. The Job Selection file navigation dialog should close.
   

   

   
   
5. From the CAM Processor window, select Process Job. The CAM Export Job should run.
   

   

   
   
6. Once finished, open the project directory folder in the system's file browser and select the following files named for your project by their extension:
   .bor (outline of your board)
   .cmp (copper design for the top side of the board)
   .plc (silkscreen design for the top side of the board)
   .pls (silkscreen design for the bottom side of the board)
   .sol (copper design for the bottom side of the board)
   .stc (soldermask design for the top side of the board)
   .sts (soldermask design for the bottom side of the board)
   .xln (drilling instructions for the board)
   

   

   
   
7. Combine all files into a single zip archive named after your design. Optionally, open all files in the Gerber viewer program gerbv to inspect them.
