How to export CircuitMaker 2 PCB to Gerber and drill files
Gerber and NC Drill setup
First, we need to configure some options. Once the settings are configured, CircuitMaker will remember the settings for a specific project, which means you don’t need to set these options every time before you generate the files.
Right click on the project name (the .PrjPcb file) on the Projects panel, a pop-up menu will appear, click Generate Outputs.
Some Outputer are listed in the Generate output files dialog, click Configure for Gerber Files.
A window will appear that allows you to specify some options.
Select necessary layers, for example, for a 2-layer design, you need to select the following layers:
- Top Overlay
- Top Paste
- Top Solder
- Top Layer
- Bottom Layer
- Bottom Solder
- Bottom Paste
- Bottom Overlay
- Outline (Note that different Mechanical layer can be used for outline, in this example, it’s M2)
If it’s a 4-layer or 6-layer design, don’t forget to select the inner layers.
|Please don’t check Keep-Out Layer (it will be exported to a .GKO file), our system looks for .GKO and may grab it as the outline. The Keep-Out Layer is used to put objects that blocks or prevents the placement of copper objects within an area.|
To have a cutout (remove all material), just draw the shape on outline layer.

Drill Drawing tab
Check Embedded apertures (RS274X)
Click OK button to finish the Gerber Setup.
NC Drill Setup
Click on Configure on the right side of NC Drill Files.
Use 2:4 for format
Check Suppress leading zeroes
Check Reference to absolute origin
Check Generate separate NC Drill files for plated & non-plated holes
Check Use drilled slot command (G85)
Check both Gerber Files and NC Drill Files, click Generate button.
CircuitMaker will say "The project has modifications…", just click Save and Commit changes.
Then click OK in the Save to Server dialog.
Click the Release button, this will save the generated files to cloud.
A window called Confirm Release will appear, you can write a release note if you want, then click OK.
A new windows will say "Project has been released successfully, open in Web Browser."
Click on open in Web Browser, this will open the released files in a web browser. Click Hide Files to show the file, then click the download icon to download the Gerber and drill files.
Verify the files
Before uploading your Gerbers and drill file to JLCPCB for production, it’s highly recommended to cross-check the generated files with a 3rd-party Gerber viewer.
If you find any issues, fix them and export the Gerber/Drill files and check them in the Gerber viewer again.
There are some nice Gerber viewers here and there, just use the one you feel handy.
If everything is OK, now you can upload the zip to JLCPCB to place the order.
