Re: gEDA-user: BatchPCB

[Stuart Brorson <sdb@xxxxxxxxxx>]

It would be interesting to view this board using gerbv-2.0.X.  The
latest gerbv includes some facilities for debugging low-level Gerber
problems under the "analysis" menu item (IIRC).  gerbv also now has
some error reporting during the file parsing.

I looked at your posting on sparkfun.  The Gerber looks OK, so I don't
think gerbv will complain.  This is supported by the fact that other
checkers say your Gerbers are OK.

If I had to guess anything, I'd guess that *their* machine is choking
on %LNFRONT*% (can't handle standard but uncommon Gerber codes), and
then gets confused about what's a D and what's a G code.

As somebody on that list suggested, a work-around is to delete the
%LNFRONT*% and all other %LN lines from your Gerbers.

If the board house actually has live humans you can communicate with,
you can ask them if their machine supports the %LN<layer> code.

Cheers,

Stuart
