Re: [ANN] PCB Multiplyer (early test version)

 

Thank you Markus for this interesting utility.
When needed, it will save a lot of time and clicks :)
I run it as a test on my Windows 7 Home Basic.
Its learning curve is 1 or 2 seconds at most :)

Hi,

often when I finish a design with KiCad, I want to print more than one
of them on a single board. Of course one can do that by copying and
moving the whole content in PCBnew. This has some disadvantages however:
- Selecting and placing the desired content is error-prone and
sometimes a lot of trial and error.
- Every time you make changes to the design, you have to start over
with copying and moving.
- It is not easy find the best fit to a certain board size and it is
hard to adjust it to other sizes.

So I tried to implement this function myself and ended with a little
application to do the job. Screenshots:
- The original board in PCBnew:
- PCB Multiplyer application:
- The resulting bord in in PCBnew:

Note that the application is limited to rectangular designs and boards.

You can download the application here:

It requires a Java Runtime Environment (JRE) 1.6 or greater. Start by
double clicking pcbmultiplyer.jar.
This a an early test version that is fully functional, free for
non-commercial use and comes with no warranty of any kind. It might be
released as open source under CPL in future.

Please let me know what you think about it and also let me know if you
find any bugs.

Perhaps this highlights that some form of inbuilt scripting / macro
functionality within pcbnew might be something to be looked into.

I have implemented some more features and brushed up the existing application:


In the first version, you were only able to select a target board size and the software tried to fit as many designs as possible. In the new version you can also specify the multiples in x- and y-direction and the software will create the result and calculate the target board size itself.
Also the layout preview is now updated on the fly while you change the settings. So you can more quickly find out good setups.

Re: Freeerouter Lockup Problem.

 

I found a workaround to the freerouter being "write-protected" problem. If I download the freeroute.jnlp file and launch it locally (as
opposed to using webstart) then it works fine and allows me to modify the settings as usual...very strange....it's been working
flawlessly until now. In any case I can continue to push the ball forward now.
Freeerouter Lockup Problem.

 

Hi Guys a little off topic but I'm hoping someone may have encountered this and has a solution handy, I'm getting nowhere...

I have a problem with KiCAD/freerouter. I was routing a large 6 layer PCB that was routing for about 3/4 days when I ran another two
threads from the same instance of freerouter in order to route two small boards, and all was running well, there was lots of CPU
and RAM available, then I began routing yet another, and the whole thing then froze up.

Okay, so sadly I have to restart everything, but that's not the problem.

The problem is that now after restarting freerouter, I cannot change any of the Freerouter rules such as the Net Classes, it's as if
everything is write protected, I've looked everywhere I can think of for a lock file (I'm running Kubunru Linux). Does anyone know if
there is some sort of lock file or something that I need to delete in order to get things back to normal? Or is this a java thing? Do I
need to reset some Java file squirreled away somewhere?

Hello Charles,

There is no flaw in LTspice - all SPICE3-compatible programs treat only the netlist order as important; the pin names are irrelevant to a SPICE parser.

The problem is not a new one, and applies to many EDA suites, and is why often there are two sets of schematic symbols provided: one geared intended for PCB netlisting with focus on pin numbers and the other for simulation.

The neatest solution would be for KiCAD schematic symbols to have a separate SPICENETLISTORDER attribute that the netlister used instead, when generating a SPICE netlist.

copying/moving artwork to a different layer in module editor

 

I have 2 related questions.

First, is it possible to copy or move artwork to a different layer in Module editor? Specifically, I have artwork on SoldP_Back and I want it on SilkS_Front.

The background is that the artwork was imported into the module using bitmap2component, which brings up the related question: Is it possible to control which layer the artwork is placed on when using bitmap2component?

No need, the function is already there.

In the Lib editor:

select the correct working library 2nd icon top toolbar
open the part you want to edit.

Make your changes and change the name.

Then

Either update the current component in current library (6th icon)

The save to disk (1st icon)

or

select another working library i.e. you may want to save the new
component in your own lib (a good idea anyway)
Then save to disk (I don't think that you need to do the update in this
case, but it does not hurt to do so if you wish)

Hi Brian,

hah! Simple! Thanks.

I've checked again the manual (12.14 - saving a module to the active

of
a

of
using the save button (under Windows, it never asks for a name there).

Re: Odd PCB design [1 Attachment]

 

Off topic reply (about rotary encoder design):

Jorge, if you are designing a conventional 24-position rotary switch, your design should work OK. However, if you are trying to determine a shaft position in a _continuous_ range to the nearest 15 degrees, your rotary encoder design will not work reliably because it will give incorrect codes when the encoder sensors are lined up exactly on a boundary between the 15 degree sectors. For example, at the boundary between 10111 and 00000, the sensors might report 10111, 00000, 10000, 00110, etc.

To make a rotary encoder that works over a continuous range, you can use Gray code. See You can use a 32-entry lookup table to quickly convert the Gray code to binary.

Cheers,
- Jan

Re: How to Connect Ratsnets in PCBlayout without making netlist .

Andy Eskelson
 

You cannot have a ratsnest without a netlist, which is usually generated
bu the schematic program eeschema.

So if you do have have a ratsnest, where did it come from?


Without a netlist you would be using pcbnew like a simple graphics
package to draw tracks and so on. Doing things like that will mean that
you cannot use any of the DRC checking.

The grid dots, you are prob just zoomed out too far, beyond a given
point they are too small to render. If you are working at this zoom
level change the grid size and they should appear.
