Gerber.cam JobforTwo-LayerBoards
The gerber.cam job uses the GERBERAUTO and GERBER drivers.
These generate files in the RS-274D format. It is set up for two-layer
boards which are to receive a solder stop mask on the component and
onthesolderingside,andistoreceiveasilkscreenprint.
Load the job by double-clicking on the gerber.cam entry in the tree view

The second message advises you that more than one signal layer is active
at the same time. Normally only one signal layer is active while output is
generated. However, when generating the wheel, all the layers need to
be active at the same time in order to form a common aperture table for
allGerberoutput.
