Now i should be able to retrieve all points that created H (or all important points that one can create H using them and some simple drawing algorithms) and send them to Serial port and from there to mechanical sections of machine.
How do you drive the hardware, with an instruction(s) to etch a line from X->Y or to etch a 'dot' at (x,y).
If it's just a dot, then it's a rasterisation problem. You could take the inkscape drawing and export it to a bitmap; then interpret that into your drawing engine.
Off the top of my head, you could also make a smaller bitmap dump of the SVG, and interpret the points as an interconnected mesh. (assuming monochrone), if two adjacent points are black, then you need to etch from X->Y, so you'd map the mesh to the dimensions of the machine, and spit out vectors. (I'm not sure this method works, it requires some more thought, it would probably suffer from missing very thin segments at a pariticlar dimension.)
Ghostscript must have solved this reasterisation problem.
