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...
