Ground Pour |
I am going to finish this tutorial with some notes on editing polygons. First, let’s look at how differently the polygon fill behaves when the outline completely contains the layout. Select the MOVE command and right click between the pads of C4 in the lower right-hand corner. This causes Eagle to select the bottom right-hand corner of the polygon’s outline. You can tell this because only the bottom and right sides have an altered look:
Escape from holding the corner and grab the right side of the polygon. To do this, left click above C4. The trace from C4 up to Q5 will light up. Right click and the whole right side of the polygon is highlighted.
Now left click to select that side so that you see this
and move it out to the right 100 mils so that you have this
Do another RATSNEST command and you will see no change compared to what we already had. As before, Eagle does not fill in where there are no pads or trace corners. But if you move out all four sides of the polygone, this is what you will get before the RATSNEST command
and after

the,
your message is too cryptic to offer a tip. there are times when “change layer bottom” does not prevent the route tool from reverting to the top layer when you are starting a new trace from an existing trace that is in the top layer. that’s all that comes to mind and that’s just eagle. you have to take your mouse up to the route tool bar and click on the layer you want.
good luck, paul

Thanks for the tutorial AND the libraries, this is extremely useful for noobs like me. Your detailed description of the ground pour is the best I’ve seen on the Net, thanks for taking time to do this!

Loving these tutorials, got my first pcbs started with your help. Thanks.
I’m having trouble getting my top and bottom layer pours to ‘work together’ they are wiping out traces in each ones level. Like this:

Any tips? is there a way to make a board with just a single layer, this would seem to make sense for small stompbox projects, or am i misunderstanding something fundamental about pcb design?

I got it figured out! I was clicking on the pour rather than the traces to change the layer.

Great tutorail gauss, thanks for the librarys. I made my first pcb, i don’t know if its going to work, but looks ok.
Are you going to continue this tuto? I had trouble withe the tool “autorute”, didn’t like the way the ground line came out.
How do you make de ground line stays around the pcb?
And finally how do i export my pcb to another program, like photoshop, to print it, with other pcbs?

Great tutorial, but what do those six commands actually do? Becasue now eagle thinks my board is actually 3.7 metres across and I cant seem to change it back…

Parker said:
Ah sorry my mistake I was assuming ‘mil’ was short for ‘millimetres’ which apparently it isnt? Must be a yank thing…
Again this is a fantastic tutorial – cheers

gm-
I also got the error when I entered the ch lay bot command, because I was still working from the new->schematic from the last tutorial.
If anyone else gets the error, it might be because you are working on a schematic instead of a board. Right click your project and go new ->board.

Parker-
A ‘mil’ is 0.001 inches.
I’ve seen lots of people mistake it as an abbreviation for millimeter, however
1 mil = 0.0254 millimeters

could you change c4 or c1 to filter out some treble or simulate rolling your treble knob on your guitar back as I have had no luck wiring in a treble control in this circuit and I like with the treble all yhe way off

Why does only the “square” package show up for every device in the supply library? Did I do something wrong?
