Problem with gerber file dimensions

autodeskguest

Hi, when I create gerber data and drill files I see the following in my

gerber viewer:

I remember I have to do some settings in the window below. But I can't

remember what settings I have to do.

  • the drd file seems to be correct.

     

    Maybe your problem is related to the following topic: "Offset in CAM Output"

     

    Did you set the option "Positive coords" when generating Gerder data ?

    Ben,

     

    Thank you for replying.

     

    These are the first few lines of the DRD file -

    By default, the x and y offsets where '0' and I didnt make any changes

    to them.

     

    Is there something I need to do before I run Excellon ? Some one, on the

    internet, had suggested running drillcfg.ulp? What does this do ?

    Normally a drill file generated by Eagle using the Excellon device has

    no "header". So, GC Preview shouldn't recognize a header and ignore it...

    How do the first two or three lines of your *.drd file look like (you

    can use a text editor to open it) ?

     

    When generating the drill file: is the offset for "x" and "y" in the

    CAM processor set to "0" (zero) ?

    Hello Ben,

     

    I use Excellon to generate the drill data. While importing the drill

    data using GC-Prevue, I set the - Whole digit to 1 and Precision to

    4. But I see that my drill hole position are offset from where they

    are supposed to be. They don't overlap with the pads in the other

    layers.

     

    Also when I import the drd file , I get the message saying " Ignoring

    information in the header ".  Is that how it is supposed to be. I am

    new to PCB design and I apologize if my questions is very amatuer.

     

    Thank you.

    if you are using the "EXCELLON" device when generating drill data

    with Eagle, you have to setup your Gerber viewer (it looks like

    "GC-Preview") to:

    "Whole Digits: 1"

    "Precision: 4"

     

    The rest is correct
