Noob at this... trying to generate Gerber and its too big

Glad to know you are successful .

I think it may have just been that viewer, because this one seems to

There are some aspects of the Gerber and Excellon (drill) file formats

which are not as well defined as one might hope. For example,

coordinates are quoted in multiples of the resolution, but the

resolution has to be guessed at. Eagle uses a fine resolution (this

actually changed between V6 and V7, I think) which some viewers don't

cope with. Some, rather obscurely, cope with it in the Gerbers but not

in the Excellon, resulting in the drills appearing nowhere near where

they should be.

It's possible the TXT file you removed confused the first viewer in that

way, but the Paragon one works better.

Personally, I never use web-based tools if I can install a better one.

There are several free ones available. I use gerbv.

why do you have vias shorting (or what looks like shorting)to adjacent

traces?

There is plenty of room available for you to work with--why not use it?

Success!

I ignored the preview stuff and uploaded it to a PCB site... and voila!

Ok... got the cutoff issue resolved, just had to redraw the dimensions.  But the drill file is still making it too big

Ok well, the drill file (at least in my case) is definitely the cause the big board.  I left out the TXT file and voila, its the right size (but it is still cut off like before...)

Not sure if its just my computer but I can't see that picture; its white.

anyway, I completely re-made the circuit.  I've attached it as well.  Now I have a problem when I export as CAM, when I render the files in the webGerber, the bottom of the circuit is cut off.  Also, the holes don't line up where they should; I think they are what is making the board bigger than the circuit in the previous circuit as well.

Attached are the gerber files and the original .brd file in a Zip.  Try running the gerber files through the WebGerber I linked above to see what I am talking about.  And if you know what the problem is, please look in the .brd and try to fix it.  I don't know what's going wrong but it's sort of annoying

Also, There is no layer 20 outline thing anymore.  At all.  You may be able to see that in the .brd file.  That may also be part of the problem...

I moved your zip file layout over to the origin (did group move) & generated the gerbers (use the CAM instructions from the manual to see the easy steps).

There was some sort of error in opening your zip files, maybe some trace or lib info was not there.

I then ran the gerb files into your 3d viewer:

This is what I get.

I see nothing wrong with the file...
