Hi Dick,

Thanks for the response. This is the original email from Lorenzo for
the original patch:

I uploaded the file gridorigin-r2010.diff.gz

Only slightly tested (but is a really simple patch anyway).

Notes:
- I added the tool under the aux axis tool, with the same icon. It
could be put under the show grid button maybe. With a new icon :P
- There may be some fuzz in the patch because I also have other in
house modifications. Please note in pcbnew/tool_pcb there are some
AddSeparator tagged to removal; I kept it to avoid invalidating the
patch (I removed separators to be able the use the 800x480 screen on
the EEE);
- I flagged the m_UserGridIsON. It seems to be unused;
- The juice of the computation is in common/zoom.cpp. That seems to be
the only place involved with grid computations;
- The origin is not saved in the .brd file. I'm not sure if it could
be useful... anyway I thing pcbnew/ioascii.cpp is the place to look
into for it.

Hope to make Dick and other people happy :P (I'm already using this :D)

There is nothing else in the archives relating to the grid origin as
far as I can see. The original patch I guess is lost along with the
kicad-devel yahoo group.

I will dig around the source and see if I can add the functionality as
I'm sure it is more expected to be saved if it has changed.

Best Regards,

Brian.
