I have been using laserCut by bmsleight, for a while. As I do not need the 3D stuff for my purpose, I did remove 3D stuff, like cube([x,y,z]) => square([x,y]). Now I can directly export dxf files right out of OpenSCAD. And in addition, I now can engrave/raster in such a way that I can visually see the result right away, while working in OpenSCAD. The output is then exported to SVG (or pdf).
