Craig,
My first milled PCB seemed to take F-O-R-E-V-E-R to mill. Turned-out
the Gcode was not at all optimized. After running the Gcode through an
optimizer, my milling time was cut by 60-70%. See my blog entry for
details
<http://woodworkerbcncrouterproject.blogspot.com/2010/06/gcode-optimizat\
ion.html> . If it works for your Gcode, it would be totally worth the
effort.
The results of your milling look outstanding. I tend to get a lot of
"curling" of the copper
<http://woodworkerbcncrouterproject.blogspot.com/2010/06/pcb-milling-att\
empt-2.html> at the edges - not sure if it the tool or some operator
issue. I still need a lot more milling experience, to be sure.

small cuts on the bottom side related to the copper pour that slowed
things down.
