Ranger 3 is a very early PCB design tool from SeeTrax. It appears to have been replaced by the SeeTrax CAE package, but the company still provides some support.
Generating Gerbers and Drills
We need a zip file containing gerber layers in RS-274X Extended format along with an Excellon/NC drill file.
One of the gerber layers should contain a watertight board outline by itself without any measurements, text, or fab notes. We use this layer to calculate your board cost, and to mill your board.
Ranger 3 doesn’t automatically include the tool sizes in the
Drill Data.txt file, so we have instructions for adding them manually from the
drill tool info.txt file.
Finally, we need the files renamed to match our suggested naming pattern so we can detect each layer correctly. You can leave out the
drill tool info.txt files.
