A Gerber file for each section of your electronic circuit design is what you need if you want to create a PCB.
In Eagle, open Board view. Click the “CAM” button or choose “File -> CAM Procesor”. This will open the CAM Processor tool that is used to generate the files.
Here you can define the sections you want to create files for.
To simplify creating Gerber files, you can use the predefined job of myProto. This is the file myProto RS-274x 2layers.cam for two-layer circuits and the file myProto RS-274x 4layers.cam for four-layer circuits.
We recommend that you put these two files in the directory C:\EAGLE-x.x.x\cam
To open it in the CAM Processor click “File -> Open -> Job”
Browse to your /eagle/cam/ folder, and you should see a file called. Choose it and click “Open”.
You will now see several tabs in the CAM Processor. Each of these tabs will generate a Gerber file.
Click on “Process Job” to output the Gerber files. You will find the files in your project directory folder.
Step 4: Check output files
You will get 10 RS274-x format gerber files with myProto RS-274x 2 layers:
