After LG mentioned "way back when the raster depth was .9... (I really thought it was 1.0 but have not located an authoritative reference yet)", I came across this FAQ from way back in 2007. About the time I purchased my machine.

Anyways, I had totally forgot about this promised feature and I wonder if it is officially dead now.. or still may see the light of day sometime.

Can the machine use G-Code programs?The software cannot import or export in G-code presently. Advanced versions of the software
will have the ability to import and export G-code.
When will the advanced software package be available?
The advanced software package is scheduled for release in 2007. The price has not been
determined yet.
