Hi all,

Is there an open source tool or KiCad plugin that'll convert
a KiCad PCB file to whatever format Seeeed Fucion wants?

I found Osh Park super easy to work with as they have a nice
web gooey to do this and can accept KiCad PCB files.

Seeeed Fusion, however, has instructions on exporting Gerber
files manually, which I followed, but which their system
did not accept. It seems like the kind of conversion that
could be automated away with some software.

Googled around, didn't find anything.

If you know of something that does, this, I'd like to use it.

I usually generate all my gerber files with a little script, that I have in all my KiCAD
projects in some form; it uses the KiCAD python bindings (so scripting needs to be compiled with Kicad)

Just invoke with the PCB and it creates a subdirectory plot/ which should contain everything
needed. Zip up the plot/ subdirectory, and you're ready to go.

I find that board houses sometimes have issues with the newer Gerber formats, so switching off
the attributes might be what is needed in your case; already done in this script
