Just noticed your ref to me, sorry for the late reply.
I use different fixture offsets for the board
sides. For the bottom of the board, I use G55
with the origin (0,0) at the lower right corner
of the fixture and for the top of the board, I
use G54 with the origin at the lower left corner of the Fixture.
This way, the fixture pocket is approximately the
size of the board stock and I set the origins
when I milled the pocket out to provide the
necessary fences and then saved these offsets
for future usage. The fixture is permanently
mounted on the router and I have homing
switches. Standard operating procedure is to
power up the machine, home it, and then load the
offset table. Now the machine knows the offsets
for the fixture and where my touch off plate is (referenced in G53).
I have customized my "user-gcode.h" to
automatically handle the necessary inclusion of
G54, G55 for the top or bottom files and the
tool change routine (which only comes into play
in drilling and milling) to do a subroutine to
G53 for tool length measurement on the touch pad.
I don't worry about a tool change for etching as
I am using autoleveling and I found out the hard
way that tool change routines and autolevel don't
get along. This part is a work in progress as I
am constantly changing the way I do things. YMMV:})
