Ah ok now i know what you wanted. For that you have to put the text into
the milling layer (46). If the text is normal it will be on the top side
and when mirrored it appears on the bottom side. In pcb-gcode you have
to activate "generate text" in the "generation options" tab. Than after
generation you will see a preview of the text and the output for the
text is in a file called $basename.top.text.ngc and $basename.bot.text.ngc.
I tried it myself and it works as expected for engraving result. :)
I doesn't like the way that pcb-gcode normally will mill away all copper
which is not used. Therefore i put a polygon over the whole board with a
gap of ~0,2mm between all traces. Than pcb-gcode will only mill away
these small 0.2mm width lines around the traces which is much faster and
preserves your precious router bit. :)
