I am not sure if it is a dxf file problem, but lw4 does not create the gcode file correctly. Some lines are dessapeared.
Diameter of the laser 0,15 mm

With lw3 the gcode is created correctly.
The files:

I think that all the lines are polylines.
When you can, try to make the gcode with lw4.There are two parts. 1 cut and 2 cut light0 .
If both are select at te same time, the gcode generated has missed paths. But if the blocks are selected and drag separately the gcode generated is ok.
In part 1, cut, there are two pieces together, share some laser strokes. Maybe this is the problem, share laser passes.

LW4 combines paths in an operation using polygon rules. If you place two solid objects against each other they become a single solid object. Likewise if you place 2 holes against each other they become 1 hole. If you place a solid object inside another solid object it becomes a hole. It does this so it can reliably decide what’s inside and what’s outside.

@Todd_Fleming Ok. Thanks for your answer.
