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

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,

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.
