Milling Circuit Boards

Hi All,
Here is an update! After spending countless hours using
TOPO,TurboCad,Eagle and Target here are my findings. TOPO will
take a BMP and turn it into a DXF. The problem with using TOPO
to make circuit boards is, the program adds tons of up and down
commands. The conversion is also plagued with the traveling
salesman syndrome.
Eagle with it's script looked great until I did a larger
circuit board. Three 14pin ICs and some traces resulted in 16,000
lines of code.
Target had the same problems as Eagle to a lesser degree, but
the program is not a easy to use as Eagle. I went back to TurboCad
using a new approach. I found out that when you convert a DXF to
a Gcode file, the machine will move the same way as you drew the
outlines. The trick is to stay in one area at a time and to draw
as much outline at one time as you can before hitting finish. Make
each trace of the circuit board one long line. Then hit finish. If
you draw each trace as several seperate lines, the machine will move
up and down for each line. Jumping around on the drawing to touchup
or correct will result in a final GCode that will move the same way.
I have a GCode file that makes a six IC circuit with twelve
transistors.(4"X6") My machine takes an hour and twenty-minutes to
mill the board. I am hoping to cut this to 60 minutes while adding
starter holes for components.
