Problem with gerber file dimensions

Ben,

Now I find that the Drills are aligned properly with the layers associated

with the component layer. But there is an offset in the board edge between

the layers associated with components side and those associated with solder

side.

Do we need to keep the 'mirror' option enabled for layers associated with

the solder side ?

Regards,

Ashwath

the drd file seems to be correct.

 

Maybe your problem is related to the following topic: "Offset in CAM

Output"

 

Did you set the option "Positive coords" when generating Gerder data ?

These are the first few lines of the DRD file -

By default, the x and y offsets where '0' and I didnt make any changes to

them.

 

Is there something I need to do before I run Excellon ? Some one, on the

internet, had suggested running drillcfg.ulp? What does this do ?

Normally a drill file generated by Eagle using the Excellon device has

no "header". So, GC Preview shouldn't recognize a header and ignore

it...

How do the first two or three lines of your *.drd file look like (you

can use a text editor to open it) ?

 

When generating the drill file: is the offset for "x" and "y" in the CAM

processor set to "0" (zero) ?

Hello Ben,

 

I use Excellon to generate the drill data. While importing the drill

data using GC-Prevue, I set the - Whole digit to 1 and Precision to 4.

But I see that my drill hole position are offset from where they are

supposed to be. They don't overlap with the pads in the other layers.

 

Also when I import the drd file , I get the message saying " Ignoring

information in the header ".  Is that how it is supposed to be. I am

new to PCB design and I apologize if my questions is very amatuer.

 

Thank you.

if you are using the "EXCELLON" device when generating drill data with

Eagle, you have to setup your Gerber viewer (it looks like

"GC-Preview") to:

"Whole Digits: 1"

"Precision: 4"

 

The rest is correct

I remember I have to do some settings in the window below. But I

can't remember what settings I have to do.
