Hi Kenneth,

Good to hear from you! The resist pens sound like good idea. And the
"modified" Gcode certainly seems to fit the "plotter" approach to
PCB's. Good ideas! I'll have to keep them and the "mirror image" in
mind.

The spring holder sounds like a part I need. I'm trying to adapt HP
7475 plotter pins.

Sorry to hear about the bad experience with the package. That would
certainly turn one off on sharing. Yes, I wish everyone was honest
too.
