Re: Footprint for trimmer potentiometer
开云体育Thanks, Reinier. I am probably odd, but I do
not like video instructions. I will study the KiCad manuals and
see if I can find the 5 mm preset pot for sale by those
suppliers. On 2024-04-11 08:58, Reinier Gerritsen

Re: Footprint for trimmer potentiometer
开云体育Creating a footprint is very similar to "normal" pcb design. There are probably tons of youtube video that will show you how to do it if you are afraid of trying yourself..Or just start with an existing footprint, "save as" you new name (create your own library!), and modify pad position, dimensions etc. Designing or modifying footprints is really something a pcb designer should know. By the way, big resellers like Mouser and Digikey have CAD models of their parts, also in KiCad format. Schematic symbols. footprints and 3D models. Library management can be a bit difficult to master. You'll need to add your own library. I would suggest to use Onedrive of similar for you own libraries. That makes it very easy to keep libraries (and pcb designs) in sync between multiple computers. Success, Reinier Op 10-4-2024 om 20:21 schreef John

Gerber export with DRC errors
Hi all,
On the FB group, someone pointed out that KiCad refuses to generate Gerber plots when there are DRC issues with the board. My experience shows otherwise. Is there any feature like this? If there is, how does it work? Thanks, Levente -- Levente Kovacs Senior Electronic Engineer W: |
Re: Problems with Audio plug2
开云体育Thanks, Brian, but that's not the problem. I
am not sure which message you are replying to, because you
haven't cited any of my message.? I have been advised how to
configure 'libraries' so that my? modified symbol file can be
added to the schematic. I am surprised that the library
management is (counter-intuitively) under 'Preferences'; I think
it's so fundamental that it should be a top-level tab. On 2024-04-01 16:31, Brian German via

Re: That question again: How to import an Eagle

Found my way in there, but using "browse libraries" to navigate to my Eagle stuff, Kicad will again not see a .lbr file, only .lib, so no apparent ability to digest Eagle there. (Clicking on the "Kicad symbol library files (*.lib)" button offers no better eyesight, despite the up/down chevrons intimating that options are on offer.) I may have to grab a strong coffee and brace myself for a Kicad upgrade, in the hope that being up to date will reduce the risk that I'm doing things the hard way. (Procrastination can do that - don't ask me how I know.) Many thanks, Erik |
Re: That question again: How to import an Eagle library?
Try adding the Eagle library in the Manage Symbol Libraries dialog.
