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.
