My first board
I had a go at making my first homebrew board last week, using a
marker pen, some etchant and a needle. First I set out the design
using software I borrowed called Easy PC. I printed the pin

Print on copper
There is a commercial product designed to make PCB's with plotters; it
includes the copper. First you plot on the copper with the right ink,
then you stick the copper to substrate, then you etch.

On a plotter? But you can plot directly onto a PCB

Check out the Links I laboriously added for some on

Direct PCB Plot.
Hi,
I think everyone on the list should take a look on this link on the
"direct PCB plot section". Seem pretty much doable, even more for the
fortunate ones that have a CNC mill around. Regular

Re: Direct PCB Plot - would it be helpful?
If there is interest I will put up the HP G/L code on one of my web-
pages. HP/Agilent provides a little support for these old, workhorse
products, but not much. I also have a "fix" for converting

Re: Direct PCB Plot - would it be helpful?
I think I missed something- what HPGL code are you
talking about?
I have a couple of those old HP plotters, both serial.
Thought that might be a good place to start for making
an engraver, use the

Re: Direct PCB Plot - would it be helpful?
Hi Jack,
Yes! I'd be interested. I still have my HP7475 from '85, although I
use it only occasionally. Laser printers do such a good job on
schematics now! What "code" do you have? I hate to see

Re: Print on copper
Hi Steve and list-
You are right, on a flat-bed plotter you can print direct to PCB, and
that is obviously much better than the system I mentioned in my post.
But, if someone does not have a

Re: Print on copper
I did look at the links on direct plotting PCB's, and discovered that
it is possible with some non-flatbed plotters to stick a PCB on a
heavy piece of paper and plot right on the PCB. My previous

Using HP GL/2 - direct printing etc.

Uh, you don't want to make this a competition. Only reason I wouldn't beat both of you is on a technicality, as mine isn't a darkroom.

I use Dyna Art. The paper just floats off in mildly warm water after
