EAGLE - GERBER file problem

SN96

Hello gents,

I was reading the tutorial on the Spark Fun Electronics website on how to generate gerber files using their script files. I did as the tutorial said and all my files came out with no problems except the darn .drd file (Drill data). I was using Pentalogix's View Mate to review my output files and for some reason when I import the .drd file, it shows several small specks way way out side the boards boundry. Also there are more "specks" than there are holes in the original design.

The .drd file is using Excellon as the device. Could it be that View Mate cant read Excellon? is this normal?

Thanks
Mike

I provided a screen shot to help explain my results with the drill data.

I think the Excellon file is just a text file.· I indicates the x, y locations for each drill bit.

The board house I use also needed the .dri file so they know the drill bit sizes.

Thanks StarMan!

This has been driving me up the wall. You are right, it is a text file and I do see data in it when I open using notepad.

I guess you can't view it in View Mate like all the other layers to see if things line up?

Here is what is inside that .drd·file (my board is very small about 2" x 2")

It looks like something·has gone afoul somewhere.

The numbers after the Xs and Ys are thousanths of an inch.· You have some numbers in the range of 15 inches.

Here's the file from my latest board.· The board size is the default 3.4 x 4 for Eagle Lite.·

I got my .drd files to show up properly in View Mate. I had to change the Eagle config file and change the X,Y, Res setting from 10000 to 1000.

Then In View Mate, I had to change the import options to the proper format:

2 dec. left, 3 dec. right

Omit leading zeros selected

positon absolute selected

units english

character ASCii

It all shows·lined up but thats not to say that the output is compatable with the fab houses. I would have to try to submit the files and see if it is workable.

Thanks StarMan for your help. You certainly pointed me in the right direction.

See screen shot to see how the drill holes indeed line up with the pads, indicating it must be correct I assume.
