At this moment I only can give some tips when you want to print an Eagle
Suppose you receive the Eagle file : clock factory.brd (Dutch name :
Open the file in Eagle.You will see the print-drawing and all the parts
and even red lines
(through connections you have to make before you start putting the parts
on the print).
On the left side on the monitor screen there is a white vertical file
with a lot of symbols.
Top-left you see an *i *(info) and just below that are the "layer
settings". Click on that
symbol and you will get the "display ".
On this display you will see : Layers
The " Nr " file on the left is sometimes blue and sometimes white.When
you click on
a number the colour will change . For making a print-drawing you must
change all the
numbers to white EXCEPT nr. 16 , 17 and 18 !!! .They must be BLUE.
Then click OK and you will only see the print-drawing.
1) After that click on "File" (top-left),
-choose the printer
size (I use A4)
orientation (I use Landscape)
-alignment (I use Centre)
-area (I use Full)
Set preview ON
Then you can see where the print is on the paper. Experiment with other
Start with scale-factor = 1. Then you get the exact size for making the
Try printing on paper (cheap) and when all is okay print on film.( see :
yourself means: 5 )
Later you can change the factor , I sometimes use 2 or 2.8 or even 3x.
A higher scale-factor you can use for a personal-use-print on paper.But
the factor too high , the drawing must fit on an A4 . (or on an A3 when
you have such
a printer )
After that you must change all the numbers to white EXCEPT nr. 20 , 21
and 25 ,
they must be BLUE. Then click OK and you will see all the parts .
Repeat 1) with the same settings and after printing on film you can
put the film
on top of the other and see where the parts must be placed on the print
To be continued when I receive serious questions about the 365
I didn't tell you before.
So good luck when you start building this meter.
