The EXCELLON device has a resolution of 1/10000 inch. I suppose you

want to reduce the precision. This can be done in the file eagle.def

which is in the eagle/bin directory.

The device definition looks like this:

Type     = DrillStation

Long     = "Excellon drill station"

Init     = "%%\nM48\nM72\n"

Reset    = "M30\n"

ResX     = 10000

ResY     = 10000

;Rack     = ""

DrillSize  = "%sC%0.4f\n"        ; (Tool code, tool size)

AutoDrill  = "T%02d"             ; (Tool number)

FirstDrill = 1

BeginData  = "%%\n"

Units    = Inch

Select   = "%s\n"                ; (Drill code)

Drill    = "X%1.0fY%1.0f\n"      ; (x, y)

Info     = "Drill File Info:\n"\

           "\n"\

           " Data Mode         : Absolute\n"\

           " Units             : 1/10000 Inch\n"\

           "\n"

Change the lines ResX and ResY:

ResX     = 1000

ResY     = 1000

Now it should work as expected. Change the Units line in

the Info section as well.

Info     = "Drill File Info:\n"\

           "\n"\

           " Data Mode         : Absolute\n"\

           " Units             : 1/1000 Inch\n"\

           "\n"

By the way:

It's a coincidence tht the ast digit is always the same here.

This can have to do with the CAM Processor's option "Positive

Coordinates" which moves the whole layout into the positive

coordinate area.

Hello Bob,

You don't need to suppress the extra digit. Note that EAGLE has a 2.4 precision

format and many Gerber viewers, such as CG Prevue default to a 2.3 format so the

scaling of the drills/holes is off. Just import into GC Prevue in 2.4 precision

format for the drills/holes and will be well.

Regards, Philip

I would have changed things in GC Prevue to view correctly except that I

saw the last digit, the "8" and the "1" there, and I knew that they were

wrong.

I did not want to send out gerbers with obvious wrong numbers, even

though the PCB company's are very good at deciphering these differences

and making them correct in the final product.

I will change the eagle.def file to make the output correct, as per the

previous posts by cadsoft.  I'm not sure if that response is in the

manual, but maybe it should be... OR, maybe an extra added addendum maybe ??

Thank you !

Well, now it's REALLY screwed up !!   I did this simple thing and it's

still bad !  I have been using GC Prevue for over 20 years now, and I

haven't had this much trouble.   Output still is WAY too large.  I have

been using Eagle for 10 years now and have had to mess with things like

this, but this is definitely the most trouble I have had.

I am now officially frustrated.

My problem must be with GC Prevue...   I output 2 Excellon files.  One

with 1/10000  and got the usual 10X output.  I then tried it again with

eagle.def specifying  a 1/1000 resolution and sure enough, the output is

rounded correct and the right number of digits.

Guess I better reload GC Prevue or something.  GC Prevue will not load

it at all with the correct excellon output.

Is there a newer and better alternative to GC Prevue these days ??????

OK, so now the Eagle Excellon output is good.

I was also able to read it in correctly (almost) into GC Prevue.

However, as I am reading in mils or 1000th of an inch, I don't know why,

but I had to tell GC Prevue that I had to specify "1 Whole Digits" and,

"3 Precision"  AND had to say Inch rather than mm.   These "choices" are

not really consistent with my excellon output file though.  There is no

mantissa, which is eluded to in their setup.

Now I just have to see why GC Prevue is only reading one of the drill

tool sizes correctly.  That's another problem I haven't had in a very

long time.

Still wondering about some other program that has a bit better

consistency in their number formats.

OK, just one more time on this here...

The inches vs. mils problem might have to do with drill tool size AND XY

position.   Tool size is in inches and XY is in mils.

There is not really anything that says one format for drill size and

another for XY position.  I think that's where my confusion lies or is

related to.

I cannot find where to adjust this format in eagle.def in the Excellon

area either.  I only see the option to edit the drill size length
