When I reverted your change, I mentioned it on the irc channel, and
explained why in the commit log.  Sorry you did not see it.  Here is
the log message I left:

http://cvs.linuxcnc.org/cvs/emc2/share/axis/images/axis.ngc?rev=1.7


I never had a problem with moving the splash screen, but I do think
doing it with G92 is a bad idea.  This is for two reasons:  (1) If a
user aborts the splash screen run, he will have offsets remaining that
are confusing, and (2) if a user jogs before running it, it will not
run at the location the preview is showing.  I think both of these
would be quite baffling to a new user, the one you are trying to help.

I like the current solution much better.  I think it accomplishes
the same goal without causing the confusion.

Another change you suggested, which is to change the safety height
to zero or below, violates a user expectation that the program can
be run with top of material set to zero.  For that reason I am
against that change, and I think putting the comments in to make a
"mini tutorial" about how to touch off Z is a much better solution.

Please, let's not spend any time questioning each other's motives
here.  I have no personal conflict with you and I hope you don't
invent one where there is none.  The tone of your message confused
me because I didn't know there were any hard feelings after we came
to a mutually-agreed-upon solution on the list yesterday.
