I also got a message from allpcb that the file format is not supported. I had
the option "include extended attributes" checked in the plot menu.
The kicad-pcb version is 4.0.7
In September I used allpcb too but then the kicad-pcb version was 4.0.6, no
I have compared the 2 gerber files, the file created with 4.0.7 has 3 extra
lines in the header (or top) of the file :
Further I created for testing 2 sets of files with the above mentioned option
on and off, there is no difference in the generated files other then the time
and date of creation.
Question : is that option supposed to do anything ?
