I think I have found the answer. If you Print the file you will get the squares and circles that you see on the screen, even if you print to a postscript files.

However, if you Plot to a postscript file and then print that file the squares and circles disappear.

I have uploaded both postscript files to the files section into a folder called Print Plot Tests so you can see for yourself.

Interesting. I know from your website you are using Linux (Debian) so as I run Slackware I thought I would try this too. Infortunately on my laser printer I still have the squares and bubbles even if I print to a postscript file first. What printer are you using?

Hi,

I have design a very simple board, with only 1 layer. This is what I
call the "hello world Board". The website is in spanish, but you can see
the pictures:



This board is free (as in freedom) hardware and It was designed using
the Kicad software (a free software). So, its a free hardware board
designed with free software :-)

We wanted to learn how to use the kicad and to test if the gerber
files generated by kicad could be understand by our manufacturers.

As you can see, there were no problems :-) . We have manufactured 55
units

Regards, Juan

I have not reached the point of doing the PCB yet as I am still working the design. Is there no manual router? A single layer PCB, I wouldn't think, would not have the level of complexity that would require an auto route. I am new to KICAD and mean no disrespect just a question.

Yes it does have manual routing and as you say this is probably the preferable route for single sided PCBs. However, the autorouter is useful once you have an initial placement to give you an idea of which tracks are going to be the hard ones to route. It also gives you an idea of track desnity which can be important if you have a power circuit where fatter traces will be needed in places.

Umm! I had not tested the autorouter with one layer.
We always use manual routing since we hadn't technology for metalising vias. Now we are quite skillfull avoiding vias with manual routing :-)
Pedro.

I have discovered I can force the autorouter to work only on the copper side by selecting copper for both layers in the Select Layer Pairs dialog.

So, it's better you stay with 2 layers routing in any case.

That makes sense. However, on a single layer PCB you normally wish to minimise the number of links. Is there some way to get the autorouter to do this i.e. route as many tracks as possible on the copper side and as few as possible on the component side? At the moment I force the autorouter to route only on the copper side by selecting both layers as copper in the 'Select Layer Pair' dialog.

Pedro.

Is it possible to make diagonal lines like the traces?
A kind of a contour that can be associated and generated with each trace
is maybe a way?

I was evaluating a commercial package today for our R&D dept.
and I found one package that do the fill at 45 degree and
add a contour trace around each obstacle.
I inserted an example of that in the attached file Fill_Zone.jpg

This is a way to avoid too many tracks when using thinner traces for the fill and this totally avoid stair pattern...
Maybe the problem is to program this? This I can't tell, I am not a programmer...

Cu means Copper ("Cuivre" in french).
This is the layer where you sold the component.

Cmp means "Component". It's the layer where you insert and see the
components.

Even if you do a single layer layout, then, the layer "Component" can
be considered as a manual layer you will use to put some strip wire
(so, I mean, nornal wire, but not copper on the pcb).

Anyway, you can make a single layer pcb if you want: at general options,

Layers xxCu and xxCmp are the bottom and top layers of a pcb. Any other layer
is an inner layer, where you can route the tracks and zones but you cannot
solder any component nor write any reference or draw the silkscreen.

Una pcb tiene 2 caras externas: una arriba y otra abajo. Si haces una pcb
multicapa, tienes también varias capas internas. En la de arriba y en la de
abajo puedes dibujar la serigrafía de los componentes, sus referencias,
cotas, etc. En las internas no tiene sentido escribir nada, puesto que no se
ve. Y tampoco puedes soldar ningún componente dentro de la pcb, sólo arriba y
abajo.

Para una pcb casera te bastan las caras "cobre" y "componentes" y, si sólo
quieres una cara de componentes smd, te basta sólo la de "cobre". En plan
casero no se hacen ni serigrafías, ni máscaras de pasta para soldar, ni
máscaras de antisoldante, ni capas internas.

Pedro.

I am confused about layers too especially as I am trying to do a single sided PCB layour. As far as I can make out there are always at least two copper layers - the one on the bottom xxCu and the copper on the top or component side xxCmp. All other copper layers are inner copper layers and labelled as such. Trying to get the autorouter to route just on the copper side only is quite hard.

... and the utility of the layers ECO1 and ECO2?

According to the help ECO1 and ECO2 are general layers for anything you want.

Hi ,
I'm eager to see a proper 'Undo' utility (preferably upto several
levels)in KIcad (eeschema as well as pcbnew)!

Thanks,

Hello Everyone,

I am new here and I am very glad that Mr. Charras and his supporters
created this very good Open Source Program. So far is the best open
source electronic design program I have seen. Thanks so much.

I have a question for creating symbols on Eeschema. I am trying to
modify some symbols for some libraries I am creating and I have not
found the way to change the grid to be smaller once I am inside the
Library Editor. I can change the grid when I am makig the schematic,
but is it possible to change the grid inside Library Editor?

If someone can help me I will really appreciate it.

Best regards,

Eduardo Bonilla

Please contribute your symbols and modules to the library folder in the
group files section. Yahoo! Groups Links
