How to export Eagle PCB to gerber files
When you finished your design in Eagle, the last step before sending it off to the fab house is to generate gerber files. Autodesk EAGLE includes a handy computer-aided manufacturing (CAM) processor that allows you to load a CAM file and quickly generate the specific files you need for your design.
Download CAM files
Our Kind customer has made 2 layer and 4 layer CAM jobs for Eagle ( Version 9 onwards)
A good place to save this is in your Eagle folder in the
cam/ directory, since Eagle will assume your CAM files are in this folder.
Generating Your Gerber Files (up to v.7, see at the bottom for v.8+)
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.
2. Select File -> Open -> Job
3. Then navigate to your default EAGLE cam folder, choose the gerb274x.cam file, select Open.
4. Adding a second silk screen (Optional)
If you look at the tabs, you will see that you don’t have a file for silk screen bottom. For simple boards, the silk screen is usually on the top layer so that you don’t need the bottom. But if you need silk screen on bottom layer as well, follow these steps:
Change Section to something like “Silk Screen SOL”
Change File to “%N.pls”
Deselect all layers
Select layers 20 “Dimension”, 22 “bPlace” and 26 “bNames”
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 EAGLE Control Panel in your project folder.
Generating Your Drill File
1. Select the CAM Processor tool at the top of your interface or select File » CAM Processor to open the CAM processor dialog.
2. 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.
3. 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 you have created each gerber file, zip those gerbers up and upload them to JLCPCB order page.
