A few words about plasma or laser cutting

[AndrewShad]

Hello! Very impressed with your project!
I was able to generate a fairly large cutting program using a .dxf file.
I dare to say a few words on my own.
Please tell me, is it possible to add a lead-in and lead-out for plasma or laser cutting?
For example, in a straight line or an arc.
I see the order of execution of the program has already been discussed. I just wanted to add that for plasma or laser, the internal contours are cut out first, then the external ones. Moreover, the cutting direction for internal and external cuts is different, since the plasma has only one finishing side of the cut (usually to the right of the movement of the cutter).
Plus the order of making cuts is from left to right and from bottom to top.
I did some digging and found this interesting document.

Good luck!
