I am making a flash/debug cartridge for my Game Gear handheld of yore. I am making my own PCB for this and I need to, of course, lay out the edge connector in the CAD software. I've tried this in Eagle (5.3, if it matters), and even being very meticulous, I ended up with some pretty bad results where the edge connector didn't have the right spacing. I tried setting the grid spacing to be a multiple of the distances between the center of the pads, but that only helped a bit. It seems that when moving a pad in Eagle, it considers the "center" of the pad to be wherever you clicked on the pad, not the actual center. I wish there was some way to simply say "add a pad at location
Thanks,
