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

By the "size"  do you  mean gigabytes or inches?

I've found that many viewers can show boards at different scaling/zoom

levels.  So look at a known component pad spacing & use that as a reference

for any gerber viewing.

Ok so long story short, I fly RC aircraft one of them being micro size

quadcopters, and I designed a circuit for one of them.  It looks good

but when I try to export as a gerber using the CAM thing it makes the

gerber files way too big... the size of the whole circuit is only about

25mm x 25mm or so but it makes the file huge (I use an online gerber

viewer) webGerber (http://mayhewlabs.com/webGerber/)

See the recent topic "Large plot of data warning message?" below. My guess

is that you are using polygons with width=0?

I mean that when I view it in the WebGerber, the circuit is there on the board but it's tiny, only about 25x25mm like I said (1x1") but the entire circuit board is huge.... many inches.  So my tiny little circuit is sitting in the corner of the board and the rest is empty PCB...

I think it's trying to render it the size of the original freeware size, but the size of the board is correct in the program (I resized it like this... change the PCB board size in Eagle - Electronics Forums) instead of what I resized it to

I am a complete noob with PCB designing, I am just trying to make a simple circuit... its really just four small circuits connected at the power inputs (speaking of which, I forgot to put the power pads in it, I'll need to do that)

"My guess

I have no idea what that means I didn't change any of the settings in the program.  I used this cam file for the job.

"SparkFun’s CAM file"

When I first rendered as a gerber using CAM, I forgot to resize the board so it was huge just like it is when I render it now, with a tiny circuit in the corner.  But when I resized it in the program, it still renders the board huge leaving the circuit a tiny thing in the corner

It sounds like you did not change the size of the dimensions layer 20

outline.  Go there & make sure you board outline (on layer 20) matches your

desired board size.   If you don't change it, eagle starts off with a

rather large board.

You can  turn off the display of all the other layers & just show layer 20

to see the shape/size of your board.

I'll try that when I get home. Thanks

Is Layer 20 the white outline that you can move around?  If so thats what I've been trying to size.

Layer 20 dimension/outline is a thin whitish line (unless you set up colors

differently).

BE SURE to check the lower left corner is on the (0,0) crosshair (you will

see a crosshair at (0,0).   coordinates are shown at the upper left of the

screen  If your square outline is put somewhere else, perhaps the

gerbermaker still uses (0,0) as its starting point (I'm not sure about

that).   Be safe, start at (0,0).

This is what I get.

I see nothing wrong with the file...

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:

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...

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...)
