It is perfect to have fast way to produce PCB. For those of us, who have CNC milling machine available, is to mill the “printed” circuits one solution. It requires to have suitable milling machine with sufficient accuracy, working tool (HPTec V-groove cutter type 802.9 seems to be ideal for me, it is possible to buy it at http://www.cncshop.cz/drazkovaci-freza-30-600-v-profil-typ-802-9 ) and of course the software, which can convert PCB design to G-code for CNC milling machine. As far as I know, one of the most widely used PCB design software especially among the enthusiasts is Eagle from http://www.cadsoftusa.com/ . One of its feature is create the user language program (ULP), which can be used for many purposes and one of them is to generate G-code.

I decided to build CNC milling machine approximately 5 years ago. After some experiments in the field of foam cutting devices I built my first unit for wooden and  glass fibre materials . It was simple machine without deep accuracy, but it means my first experience  for me and it became milestone for my planned construction of precise CNC milling machine. In the end of year 2010 I designed the construction, which was finished at the  moment.
