Excellon output...  Extra digits at end of X and Y positions

Former Member

 

I cannot seem to figure out how to suppress this extra end "1" digit

for the X position and an extra "8" digit for the Y position of the

excellon drill output (Eagle 5.50 or 5.60 these days)

 

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 as far

as what the comments in eagle.def say.

 

 

  For example, I get this:

 

T01

X8981Y13548

X8971Y12958

X8971Y12378

X9771Y13498

X9761Y12828

X9761Y12238

X1101Y15808

X971Y15198

X811Y14628

....

 

when I SHOULD be getting this:

 

T01

X898Y1354

X897Y1295

X897Y1237

X977Y1349

X976Y1282

X976Y1223

X110Y1580

X97Y1519

X81Y1462

 

 

They are the same except for the extra constant digits.  If I edit them

off, GC Prevue reads it just fine.

 

 

How can I fix this besides editing the output file

by hand  or editor ?   It may be that the PCB makers have been editing

these off for me for years, but this should not have to be the case.

 

 

Thanks,

    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.

    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 !
