Thank you for suggestion. Very nice idea, but it did not work for me.
I've uploaded my custom.3.0.binding file to edrefcard and get almost empty chart

Something like this:
https://edrefcard.info/binds/yfgdov
My assumption is that
edrefcard does not work with 3.0 bindings. Or am I doing something wrong?
Sincerely,
jsBulat.
Interesting - I just did it for my setup (I don't use tflight) and it produced a correct graphic (well correct graphics as I have MFDs too) but didn't give me a "saved as" reference, just an invalid link (i.e. not a link to a binds directory / archive on their site such as your example). Mine should look like this:
https://edrefcard.info/binds/ksfbpe which it does to an extent (that is an old set).
So sorry for the duff gen, it does seem to be broken to some extent although it did work after a fashion.
EDIT: I just checked with an old 2.0 binds file and the same thing happens - the graphic is correct but there is no reference generated.
SECOND EDIT: I have raised this issue on the support thread for the ref card generator.
THIRD EDIT: Got an answer, posted it below - "If you want a permalink, you now have to provide a description in the last field of the form. "
