I’m doing a design in Eagle 4.16r2 and I have downloaded all the .cam and .dru files from the batchpcb site, but it always spits out the drill file in 2.4 normal. How do I change the sfe-gerb274x.cam so I get the dril file in 2.3 trailing (which is what the site says they are looking for)? Thank you.
Hi,
I am having the same problem. 
Did you ever find an answer?

Have a look at this old thread: viewtopic.php?t=1350
You need to edit your eagle.def file in the Excellon section so it outputs in the format you want. I’m not currently on my computer with Eagle installed so I can’t do a cut and paste for you.
What I do when I set up eagle is I make another section called EXCELLON_2.3 so when I run the CAM processor, I can select between the regular 2.4 format or the 2.3 format without having to edit the eagle.def file every time.
