How to export Gerber files from Eagle file

EAGLE is a scriptable electronic design automation (EDA) application with schematic capture, printed circuit board (PCB) layout, auto-router and computer-aided manufacturing (CAM) features. EAGLE stands for Easily Applicable Graphical Layout Editor (German: Einfach Anzuwendender Grafischer Layout-Editor) and is developed by CadSoft Computer GmbH. The company was acquired by Autodesk Inc. in 2016. EAGLE contains a schematic editor, for designing circuit diagrams. Schematics are stored in files with .SCH extension, parts are defined in device libraries with .LBR extension. Parts can be placed on many sheets and connected together through ports.
The PCB layout editor stores board files with the extension .BRD. It allows back-annotation to the schematic and auto-routing to automatically connect traces based on the connections defined in the schematic.
When you finished your PCB design in Eagle, you could generate Gerber files which is needed by PCB manufacturer. This NextPCB’s article is telling you how to export the Gerber file from Eagle software.

Step 1.Open the CAM Processor

Open your PCB layout (.brd) file in Eagle, Click the “ CAM” button or choose “File -> CAM Processor”.This will open the CAM Processor tool that is used to generate the files.

Step 2.Click File -> Open -> Job

Step 3.Then navigate to your default EAGLE cam folder, choose the GERBER_RS274x.cam file, press Open.

Step 4.Adding a second silk screen (Optional)

If you look at the Layer options, it doesn’t have a file for silk screen bottom. But if you need silk screen on bottom layer as well, follow these steps:

a. Click “Add”
b. Change Section to something like “Silk Screen SOL”
c. Change File to “%N.pls”
d. Deselect all layers
e. Select layers 20 “Dimension”, 22 “bPlace” and 26 “bNames”

Step 5.Select the Process Job button to create all of your Gerber files.You can find all of your generated Gerber files in the Autodesk EAGLEControl Panel in your project folder.

Step 6.Generating Your Drill File

a. Select the CAM Processor at the top of your interface or
select File » CAM Processor to open the CAM processor dialog.

b. You now need to load a drill CAM job to get things started. Select File » Open » Job,
and in your default EAGLE cam folder select the excellon.cam file, then select Open.

c. you'll now have a single Generate drill data tab available, which will grab the data from layers 44 Drills and
45 Holes, just what you need. Select the Process Job button to generate this file.

After those step, Gerber files and Drill data have been exported from Eagle software.
