I just upgraded to the 7.6 release and when I tried to generate my standard drill files by running CAM job => excellon.cam I get the following error message on my 4 layer board
"CAM job doesn't cover the Layer Setup! - MIssing signal layers 1 2 15 16"
A quick look at the DRC indicates the layers are setup correctly and in fact, I had a prior successful autoroute. When I try to manually add the layers, it then complains that more than 1 signal layer is active. It does seem to generate the files and they seem reasonable to a quick scan but errors are indicated in the flow
When I retreat to Eagle 7.5 the same excellon.cam job works without issue and no errors are generated. Both the Eagle 7.5 and 7.6 installations are on MacOS. Is there a new trick that I need to be aware of to make standard CAM work on 7.6 without error ? The gerber generation went without incident, but the CAM failure for the drill file generation which has worked pretty much forever is a bit annoying.
