"No filename specified!" in CAM processor even though it is

Former Member
Former Member over 11 years ago

    Greetings,

 

I'm trying the mac version of EAGLE 6.5.0. The CAM dialog gives me "No filename specified!" for any of the default .cam files, even though I have clicked the File button and browsed to a valid directory. I cannot get past this to generate Gerber files. Any words of advice?

 

...Thanks, Dave

    Thank you Richard,

     

    With a little help from another user, I've discovered what was giving me so much trouble - it was the user interface that had me so confused.

     

    What I was doing was opening the gerb274x CAM job from the control panel instead of the board editor, as in

     

    File>Open>Cam Job...

     

        Because, just selecting File>Open... from the board editor only gives you the choice of opening a board or schematic. When I was looking around for File>Open>Job... I couldn't find it! But I noticed that I could open CAM jobs from the Control Panel File>Open>Cam Job... and that's what I had been doing every time.

     

         You get the same CAM processor dialog box, with the same five tabs populated, but Process Job or Process Section result in the "No filename specified!" message.

     

        Now I see that if you open the CAM processor first, then you get the File>Open>Job... option.

     

        That subtle difference is what led to my confusion. I spent several hours trying different permutations of filenames and locations for the output job files! Now that I see the difference, I will call this a flaw in the user interface. It is confusing that some menu items behave similarly but are really different when invoking them from the Control Panel, schematic or board editor, or CAM processor. I was about to rip my hair out! Why is the File>Open Cam Job... hierarchy in the menu there in the Control Panel. Very confusing!

     

         In any case, thanks for your reply!

     

     

         ...Dave

    If you have the board editor open, the "File" menu includes "CAM

    Processor". Surely that's a pretty obvious thing to click on if you want

    to generate Gerbers from a board?

    No more so than ANY other GUI I've ever encountered. It's like that for

    reasons that you get used to after a while.

    Just like the option to open a library from the control panel, or a user

    language program, or a script, it's there so that you can edit the job

    without having to load a project first. This is helpful if you're

    setting up a new default or a company standard.

    Guest,

     

    Maybe after you've been initiated, it seems obvious. But if you've never generated a Gerber file from EAGLE before, it's not.

     

    And then what? You get a dialog box that has a tab with nothing but an asterisk in it, and a File button. What's the file button for? Selecting the output file. OK. How do you open the .cam job? There's no button for that - it's File>Open>Job.... menu. But what if you clicked on the board window in the meantime as I did. Now the menu has changed, maybe you didn't notice that. Now it's File>Open..., which does something different. But look! There's File>Open>CAM Job... because now I clicked on the control panel and it's the active window - that's what I want, right? It let's you open a CAM job gerb274x.cam. That dialog looks right, one tab for each layer. There's a File button, I can select the output filename and path, and a device. Only Process Job gives the "No filename specified!" message. I think that message is misleading and what led to my confusion. What filename is not specified? I specified an output file, I loaded the gerb274x.cam file, what filename is not specified?

     

    Well, my point is simply that if I ran into this then some other new user might too, and I hope that this thread will help them.

     

    It's a good thing that I didn't pull my hair out!

     

    ...Dave

    All I can say is that I didn't find it confusing even the very first

    time I generated Gerbers. But then I'm old-fashioned enough to have read

    the tutorial that comes supplied with the software.
