I’m working on a PCB that I plan to use Seeedstudio’s Fusion service to manufacture. I’ve designed the PCB in Eagle. Initially, I used Sparkfun’s CAM job to generate gerbers, which I viewed with Viewplot. They looked fine.
Now, I have downloaded Seeedstudio’s CAM job, generated a new set of gerbers, and it appears that the drill file doesn’t line up, but I might just be misconfiguring the viewer. I don’t want to send these gerbers off to Seeedstudio without some confirmation, though.
Can someone help? Maybe someone who has used Seeed’s CAM successfully?
Here’s a screenshot of part of the board from Eagle:

Here’s a section from the .txt file the Sparkfun CAM spit out:
Here’s the same section from the .drd file the Seeed CAM spit out:
Is one of these “more right?” Is there a config file somewhere that should specify if the hole position is centers or upper-right corners? Am I missing something?
In the end, all I want is some level of assurance that when I send these gerbers to seeedstudio, I’ll get the correct hole placement. But it looks like the locations generated by the seeed CAM job are not correct - or am I using my viewer software wrong?
