Eagle 8.6.0 Issue with loading CAM files

Okay so you folks decided to revamp the whole cam interface ... fine but

I cannot seem to load older cam files - please tell me this is backwards

compatible?

 

It insists on calling it template_empty cam and all the layers names are

pooched

 

Hmm... I don't see the layer name corruption but I agree the renaming is

annoying.

EDIT: Just saw your image (missed it at first read). I'm not sure why all your layers are messed up like that. What version of EAGLE was your old CAM file generated in? The CAM's I created in V7 seem to import fine.

Yes it is backwards compatible. Next to where it says template_empty there is a button which pops up a menu which will allow you to load up your old CAM file. When you do it will put it under the Legacy section and in my tests all the layers etc all remain correctly named and pointing at the correct design layers. You should just be able to run this as before and I believe it will use the old CAM processor. You won't of course get all the benefits of the new CAM processor which are Gerber X2 and it using polygons in the Gerber instead of raster fills which reduces Gerber size and cuts generation time dramatically.

I think what you are seeing when you think all the layer names are "pooched" is the default template layer names. It tries to be helpful and load up a template which matches your board stackup when it first loads up. If you don't like it then change it and save it as a new style CAM job or just use your old one id you prefer. I created a new CAM job to replicate one of my old 10-layer jobs and it certainly is a lot quicker to output the job on a complex board.

One thing to note though, make sure you choose the option to generate multiple drill files explicitly if your stackup has more than just through vias. You need to right click on the Drills section and choose the option called "Generate Excellon outputs based on PCB stackup". If you don't do this then you won't get anything than the through board drills generated.

I had one older profile which reacted the way I posted, the others  I

tried did have the correct layer names.

Okay - thanks for that info

I wish it would show the cam filename instead of defaulting to

template_empty.
