I load my CAM job as usual in Eagle 5.6.0, and then load the schematic for a new board, and all the CAM jobs have no layers added.
Neither the Eagle CAM jobs like gerb274x.cam nor my own custom CAM jobs have any layer information in them at all!!
What have I done, and how can I undo it? I have tried to download CAM.zip from the tools section of the user downloads from the eagle
website, and even those CAM jobs came up blank!!!
