Homebrew PCBs

The photos are phenomenal.  Did you do any continuity testing on the
small traces (under 5 mil)?  I'm doing a conversion of a C88 printer
with Mis Pro inks, so seeing what you've been able to accomplish has
me really fired up.  My printer is pretty heavily modified, so your
preheating experience has made me think about adding a small lamp
(40-60w) to my new infeed in order to preheat the board, kinda like an
easy bake oven.  This way you could load the board carrier and just
give it a minute or two to warm up, then hit print.

Once I get the finer details wrapped up, I'll post some pics of my
converted printer.

Nice Work!
