CAM process hanging on"printing aperture D10"

dandeurloo

I am trying to print my first 4 layer PCB.  I am trying to run a CAM process for printing my Gerbers.  The CAM process keeps hanging up on a screen that says "printing aperture D10".  Do these "printing aperture D's" typically take a long time to process?



Any ideas what might be the issue and how I can get these Gerbers created?


I am using EagleCAD 7.7

 

Thanks.

    Unless you provide the gerber code describing aperture D10 it will be

    hard to tell, but I suspect you may have used very thin wire for

    polygons, wich will become a very large file and take a lot of time to

    create.

    Yes, this was it!  Thank you.  Is there a preferred size of wire for creating polygons?

    Not a single value. The width parameter controls the narrowest fill you

    can achieve, and thus the smallest gap it can flood through. It also

    controls the width of the bridges across "thermal" isolation on PTH

    pads. Generally, you should go for the widest that doesn't cause you any

    problems with flood fill. That said, the corners are rounded to the

    width setting, too, so making it too wide "blurs" the shape.

    As Rob says..

    Remember the wire width requirement originates from the time when the

    fill actually happened with a round pen/aperture, and this is why inner

    and outer corner sharpness is limited to this pen diameter. If this pen

    is very thin (or 0, wich is converter to very very very thin in eagle),

    imagine the time it will take to fill it.

    Today's modern transfer tech does not have this limitation as the are

    very fine pitch pixel based. But modern tools support support converting

    the old stuff. I have been missing "flash" mode fills on Eagle for a

    long time. It would also make screen drawing a lot faster, wich you will

    notice when working with larger pcb's.
