How do you get the ERC to pass?

Asked by gratefulfrog

Hi,

I am new to Kicad having previously only used Fritzing.

I am trying to follow the Getting Started tutorial on Ubuntu 12.04, Kicad from 2104 Jan.

1. It crashes quite often, but restarting usually recovers most of what was done.

2. I made the schematic as far as step 44 in the tutorial, but now the ERC produces a bunch of errors which I cannot seem to fix.. The report is below (making it crashed the application as well).
I would really appreciate some help... Is there a mailing list or an IRC or something - French is fine too.

3. Does anyone use this tool for serious PCB design? I am not sure that I want to spend the effort to learn it if it is alpha tes software - I'm not trying to insult anyone, I do appreciate that it may work fine and I don't know what I'm doing...

Any help would be great!

Thanks,
Bob

That's very strange. It shouldn't crash.

The usefulness of eeschema ERC is debatable... pcbnew's DRC is fine,
however.

The kicad-users mailing list.

I have more than 10 board (almost 20) in full production (mostly two
sides, a couple of 4 layers, too). Other people did very complex
designs too (AFAIK at least an 8 layers)

It's not Altium or PADS but IMHO could beat Eagle blindfolded; also
can't beat the price:P

Thanks for taking the time to answer!

So, if the schema editor is not of any use, what is the workflow? All I
want to do is create some 4 layer PCBs.

Is there any document which describes this?

Also, it would be nice to know the URL of the mailing list to sign up.

Thanks,
Bob

The schema editor IS useful, it's the ERC feature that's not so
useful...

> Is there any document which describes this?

The manual IIRC describes the workflow, which is pretty conventional. In short:

eeschema: schematic -> cvpcb: assign footprints -> pcbnew: layout

Start here

https://groups.yahoo.com/neo/groups/kicad-users/info

There are also user groups in italian and spanish (don't know about
french)

Hi,

I appreciate you are trying to help me, but this is not really helping
me... Your answers really suppose a level of expertise that I do not have
with your tool.

Since I don't know how to use the tool, I tried to follow the tutorial.
But, it doesn't really work (I mean beyond being out of date) and it is a
real struggle. On top of that the crashing makes it painful.

I somehow feel that the tool may be the one I need, but it is really hard
to get into it with no decent tutorial or real help...

I am now giving up with Kicad and going to give pcb a try...

Sorry to be so pessimistic, but I have spent all the time I can afford on
it and not made enough progress to justify continuing.

Thanks anyway,
Bob

The launchpad questions funnel into the developer's mailing list. You are not talking
with people yet that can speak at your level and hold your hand.

Lorenzo said "join the user's mailing lis"t. That is the best advice you can get right
now, follow it, and ask all your questions again there.

This is your best path forward. KiCad is the right tool. You may not be using the right
version, they can tell you more on the user's mailing list.

This is your shortest path to success.

Can you help with this problem?
