• gerber outline

    From Hul Tytus@21:1/5 to All on Mon Feb 28 19:54:04 2022
    Ospark.com's quote section took a gerber .zip file (generated by Eagle version 3.5) and said it couldn't find the board outline. It showed a few
    other problems too which have been fixed, thanks to several people showing working gerber code. Oshpark's need for a different form of board outline
    seems to be the only remaining difficulty.
    I'm hoping someone who has used Oshpark (or 4pcb.com?) will send a Gerber .zip file that has been accepted to me at [email protected]. This will provide a "known good" example of a board outline that I can use as a model when generating gerber files. Also, it needn't be generated by Eagle but just be in accordance with Oshpark/4pcb's expectations.

    It's been a while since I last used Eagle, but as I remember:

    You draw the board outline on the Dimension layer 20 - ie if it's a rectangle, four lines forming a closed loop.

    I've not used Oshpark but it seems their CAM export script takes it from
    there:
    https://docs.oshpark.com/design-tools/eagle/generating-gerbers/

    (on other CAMs you may have to add the Dimension layer to copper gerbers so
    the fab picks it up from there, but that CAM generates a separate .boardoutline.ger file)

    If you did the above, is there something wrong with your lines that they
    aren't being picked up? Does a Gerber viewer make sense of your .boardoutline.ger file?

    I don't have any examples I'm afraid, but when I was using Eagle the
    dimension layer was picked up by the fab successfully (although I do recall first time around having this problem as I failed to tick it in CAM export)

    I did look at Oshpark's .cam data but not what you have mentioned.
    The outline code appears ok now but I'll keep your suggestions on record
    just in case something changes.
