Hi,

I am trying to do some light painting with an industrial robot.
Basically a long exposure photo in a dark room where the only light is an LED attached to the robot.

• I have installed the DXF2Gcode
  
• I am able to generate toolpaths
  
• 我能得到一个toolpath by adjusting the DXF2Gcode slice depth and final mill depth both to -1,00mm. (If slice is less than the final depth, multiple passes are required... hence the double toolpaths)
  
• I was able to solve the path and make the robot follow the path.
  

All is going well but I am wondering about some optimizations.

Questions:

• I want the robot to be behind the logo. Normally milling and such is done from above... like drawing on the table. I want to basically draw from underneath the table. How can I do that?
  
• Can I define the order of elements that are drawn? Some toolpath optimization is doing all the letters in seemingly random order... I understand that it comes from the G-Code and the software that generated it.
  In DXF2Gcode there is Options > Tolerances > Tolerance for common points and tolerance for curve fittings.... does not seem to make a difference. I would have expected circular features to be recognized as longer curve segments... and the generated KUKA robot code to be much fewer lines.
