Homebrew PCBs

Thanks Slavko for responding.
Do you have a link where I can see the video description you mentioned?

Hello..
It's written in video description. The data is provided by python script.
Well the workflow is like that:

-Draw board.
-export board to 800 or 1000DPI BW image -pass that image to python script
to get bitfile -load bitfile into LinuxCNC -Push start

Slavko.

p.s.
It's possible to pass just BW image to Linuxcnc but the power of my computer
is just little to low to provide data in realtime. So I do preproces data.
Maybe just better algorithm can solve that...
