Here’s a quick guide on exporting a board from Altium Designer 14 to be made by OSHPark.

1. Go to Design -> Layer Stack Manager
2. Set your stackup to be this:

.LayerStackManager

This information was derived from this FAQ.
3. Go to Project -> Compile PCB Project.  Fix any errors that could cause a problem.
4. Go to File -> Fabrication Outputs -> Gerber Files
5. Under ‘General’, set the units to be ‘Inches’ and the Format to be ‘2:4’
6. Under ‘Layers’, select the following layers:

  • Top Overlay
  • Top Paste
  • Top Solder
  • Top Layer
  • Bottom Layer
  • Bottom Solder
  • Bottom Paste
  • Bottom Overlay
  • Mechanical 15(assuming that you have drawn your board outline on mechanical 15)

Now export, save as <projectname>.cam

7. Go to File -> Fabrication Outputs -> NC Drill.  Use the following settings:

  • Units: Inches
  • Format: 2:4
  • Leading/Trailing Zeros: Suprress trailing zeros
  • Coordinate Positions: Reference to relative origin

Save as <projectname>-NCDRILL.cam

8. With the NCDRILL.cam file selected, go to File->Export->SaveDrill.  Set the extension to be .xln

9. Go to your project folder, there should now be a sub-folder called ‘Project Outputs for <Project Name>’.  Grab the following files:

  • *.xln
  • *.GBL

  • *.GKO(re-name the .GM15 file to be .GKO)

Put these all into a .zip folder.
