Re: Milling Circuit Boards
Steve,
You can use Corel. I use Turbocad. Make sure that you draw
the trace all the way around and make it overlap onto itself a
short distance. This eliminates unwanted little shorts.

Re: Gerber and Excellon to DXF
If you are planning to buy Easy-PC I still have the latest version for
sale. I had it for sale at Ebay for several weeks but no one wanted

Here's a link to the old auction site.... I'm still

Re: Gerber and Excellon to DXF
I use Easy PC, which is capable of outputting DXF and which has an add-on module that can import Gerber.

Gerber and Excellon to DXF
Does anyone know of an effective and reasonably priced software program to
convert Gerber and drill files to DXF?
Thanks for any shove in the right direction,

Re: Milling Circuit Boards
Good point. I'm used to using CorelDraw and a vinyl cutter so it
draws it differently, I guess. I make sure and join all objects
that touch so the path is only around the outside of an area. I

Printing PCB boards
I am new to this group and I have been tinkering around with making
hobby PC boards for a couple of years now (I am no pro nor do I claim

Re: Milling Circuit Boards
Steve,
An other thing about using a plotter. If you use
PLT files, you will end up with pads and traces but
they won't be connected. When a plotter draws pads it
makes a circle for each pad.

Re: Milling Circuit Boards
Hi Steve,
When you use a plotter to draw on the copper
you have to be able to slow the plotter down. If you
don't the ink will not flow fast enough. Over the years

I did try a Staedler 313 (Red) pen, just discovered I already had
one. I

Re: Milling Circuit Boards
Steve,
Don't take the plotter apart until you look at:

Also, hooking up a Dremel or other tool to a Plotter
has a drawback. Pen-up and pen-down

Re: Milling Circuit Boards
My concern was that it was becoming personal.
Tony, your website looks like you are pretty advanced. Is it
possible that John's paper is aimed more at the beginner? Reviews

It is unfortunate that this has ended up as a slanging match, and I apologize for my part in that.

You're right, and my heart bleeds for you. However, even subtracting the shipping, it was an expensive way of buying 15 sheets of paper - and at least if they'd been blank sheets I could have re-used
