you got much the same results i got.
I took it a step further and bought expensive carbide-tipped pens with  
cross-ground tip.

Didn't work because (i think) the trailing edge of this metal "tube"  
scrapes away much of the ink and it is no etch resist layer an more.

I never got plotting to copper to work, and it would have been very slow  
anyway.


IMO you are wasting your time, but with what seems a reasonable idea so it  
isn't foolish.
