This dxf I downloaded from the internet.
I have preferred to export to T2 as .plt, it's pretty simple and everything goes straight, size and lines ... I liked this scheme of colors to export in plt, but for me the colors do not change the strength of the laser, it changes the speed ; Black = 350 (my choice in vector rate), Blue = 740, Green = 870, yellow = 1000
I would rather change the laser's strength
