Been there... done that.. got the T-shirt... and get my
boards done with a PCB manufacturer now.

Getting the pens to work reliably, the ink right, the speed
of drawing right and slightly altering the Roland dxy1200
to take PCBs was a trial but not impossible. It was just
that if you didnt keep using it, the ink would go off, the
pen would take half an hour of fiddling to get it flowing
right and then there was etching and drilling....enough
said (broke about 6 X 0.5mm drill bits just getting this
setup right).
Seemed a good idea at the time since we had a plotter
anyway but it was only feasible if you were using it
almost daily.

Now with new chemical/safety regulations in NZ the
keeping, using and disposing of Ammonia Persulphate is
a huge hassle.
