Personal library not updating ...
Hi, I have a personal footprint library that is used in a project.
I have added a new footprint and closed and reopened the schematic editor but when I try to assign the new footprint the library appears unchanged !!
If I go to the PCB editor I can see the new footprint OK.
How do I flush the updated footprint library through ?? I know I can set the footprint in the PCBEditor but I prefer to keep it consistent.
Regards,
Dave

Re: Chamfers on edge connectors - how ?
Hi David,
You should always supply the fab with a mechanical drawing or fab drawing of your PCB. This is where you will specify the dimensions and tolerances. This drawing should also contain a drill chart with hole sizes and if they are to be plated through or not. As well as a notes section where you specify the materials used, copper weights, soldermask type and color, nomenclature (silk screen) color, finish (HASL, ENiG, etc) and for the fingers hard gold if that's what?you want. Typical thickness of Gold (Au) is 30 to 50 ui(micro-inches) over Ni 150-250 ui.
Hope?this helps. Glenn

Re: Chamfers on edge connectors - how ?
It's in your fabrication notes, we have a whole
block of notes on the fabrication layer.? Not saying anyone reads
them, but the instructions are there.

Re: Chamfers on edge connectors - how ?
I do not use KiCAD, but when you send your gerbers to the fab house, be sure to inform them of what you need. Most will be glad to assist. May cost a bit more to deal with edge plating. I use Electronic Interconnect (EI) as they are very helpful. Not sure how to work with Sunstone as we use EI for production work.

On further review I see that the dimensions are correct.? Don't understand how I made such an error especially since I checked a few times. But today its seems all is good.
My other error was looking at the 3SK263 as it was a duel gate which is what I wanted and the markings are not the same as the one I wanted.? But I understand now where I went wrong.
Thankyou Tony for your response

Which SOT143 footprint? In the Package_TO_SOT_SMD.pretty footprint
library, there are 4 SOT143 footprints.
SOT143s are used for all kinds of devices, not just MOSFETs. My copy
of the library?SOT143 footprints only list pad numbers, not pad
descriptions. The KiCad libraries are not atomic - there is no
1-to-1 correspondence of schematic part to footprint. You have to do
that.

I've just
noticed that the SOT143 4 footprint is too large and drain is on
the wrong tab. I thought I read a while back that the error was
corrected. From what I see its not.? I'm using ver7.? Not sure
about 6

Re: Edge cut layer and fillet command
You can design shapes in FreeCAD and then integrate with KiCAD if that helps. There is a plugin for FreeCAD.

Re: Edge cut layer and fillet command
I'll be honest and say I'd never tried this before, either, but it's
a new feature I think. In the past, I've imported complex PCB
outlines as DXFs, which is still possible. Both options are better
than adding arcs manually.

I did try it before
posting and as the edge cut layer is an outline it was possible to
select all of it rather than each segment.
After appling the fillet command, all the 90 degree bends were

I guess my post was really saying that this appears to work....Am
I missing a really obvious reason why I shouldn't do this.
Anyway, so far so good...Happy Days

Re: Edge cut layer and fillet command
Did you try it? I find that's the easiest way to answer questions
like this.
Spoiler: yes, it does work. You need to select each segment to
include before executing "Fillet".

I'm new to KiCad and have
version 7 set up with Win 11.
My board is essentially square
but the outline needs a number of cut outs to allow cables to
run through.
I need to make all the 90
degree edges curved, but the suggested method of creating
separate arcs would take a long time. I think there are about 20
to change.
Can I simply draw the outline
and then use the fillet command and set a radius for the curves?
That would be a 10 second
solution rather than probably an hour or more for this beginner.

KiCad 7.0.5 Simulation: Coupled Inductors?
I'm trying to simulate a transformer-like situation using two coupled inductors. In SPICE this is done with a 'K' statement indicating the two inductors to be coupled amongst other things.
My question is pretty simple but I'm stuck. How can I add this 'K' directive to the ngspice netlist? I can see the netlist in the Simulation workbook window (Simulation | Show Spice Netlist...) but while you can edit it it doesn't seem to be saveable.
I've seen some suggestions about modifying the schematic file (which is text), but does anyone know the 'proper' way to do this?
Thanks.

Footprint property parameters or formulas?
Is there a way in PcbNew to define footprint properties in terms of, or relative to, other properties or parameters?
I started out working out my X and Y positions by hand, on paper. When that grew unmanageable I naturally reached for a spreadsheet. Now I'm considering using Python scripting to "update PCB from spreadsheet", but I'm new to the KiCad ecosystem and wonder if there's an existing idiom for this?
Here's my spreadsheet [1]. It's like a Component Placement (.pos) file (towards the bottom), but incorporating Excel formulas. Here's the same spreadsheet in Google Sheets [2]. My plan is to use the LibreOffice API to parse and evaluate the CSV, and PcbNew scripting to copy cells to footprint properties.
The formulas layout switches on a 36 key keyboard, some of which are relative to other switches, or depend on a rotation parameter. Here's a PcbDraw render of the board [3] which is an early work in progress.

Re: Export Kicad Libraries while kicad isnt working
If Kicad 7 works, why not just import the libraries in Kicad 7?
They are just text files, like all Kicad files.
Otherwise bring your libraries to a PC not running garbage
anti-virus and move the libraries or ask your IT department to
build an air-gapped PC without the AV, export the libraries, and
done.

Re: Export Kicad Libraries while kicad isnt working
You should be able to tell any AV software to leave certain files/directories alone. Also as said inn the next post the files should be quarenteened not deleted. If you AV sox cannot do this then get rid of it. You can always disable or uninstall the AV sox, then copy the library back onto the laptop. You can then export your files to wherever you want before reinstating the AV sox. All AV sox will do this sort of thing from time to time, they are not perfect. This is why you need to learn how to manage things. There are some software products that are so old, but still working that most AV sox gets confused about. The software I'm thinking about is a very old conferencing forum software, that frequently gets tagged as a bad file. The solution is to exclude the install directory of that software from the AV scanning. Andy On Thu, 15 Jun 2023 04:46:58 -0700 lorenzo.gherardelli@... wrote: Hello everyone,
I have been using?Kicad 6 on Win10 laptop for months now and our antivirus software (Trellix Endpoint Security) at the company reported this data as a trojan C:\Program Files\KiCad\6.0\bin\brotlicommon.dll". Now the file has been deleted and I cant use any of Kicads subprograms/applications (schematic editor, symbol editor, pcb editor, etc.) anymore. This means that I cant manage any library. Also whenever I try to open an application Kicad presents me 3 different error messages.
I tried copying the deleted data from a different laptop with the same kicad version, but the antivirus software immediately deletes it after copying into my laptop.
I was hoping if I could still export all of my libraries from Kicad 6 and import them into Kicad 7. Moreover Kicad 7 is working normally and our antivirus software didnt discover any malicious data.
Here are pictures regarding the error messages that I get while opening any Kicad subprogram/applications.

I appreciate any help or suggestion to fix this dilemma.

Re: Export Kicad Libraries while kicad isnt working
The problem may be with either Trellis (most
likely) or KiCad. First, report your problem to Trellis.
Security software have no business to delete files, only
quarantine them, because false positive detections of malware
are common.? If Trellis won't co-operate, scrap it and use a
better security app. I use Avast/AVG and it seems very good.
