Thanks for testing on windows! Selection and fiducials by default have nothing to do with the xy export origin. The origin point, by default, is the top left corner of the drawing area, since pcb-rnd is using the same coordinate system for the xy export as for the GUI. You can change the origin point by palcing an object with a specific attribute makign it the "pnp origin". This pool node explains how it is done for macrofab (but the method should work with any XY template): http://repo.hu/cgi-bin/pool.cgi?cmd=show&node=macrofab Related: XY is not a real file format that is ever specified anywhere - it's just a generic concept, basically the idea of "you send the x;y coordinates of your parts in text format". Thus each fab will have their own XY format requirements, especially about the coordinate system and rotation angles. Fortunately our XY export plugin uses templates and you can write a template that produces the exact output your fab requires. There are keywords for all possible interpretations of data, for example we have different keywords for rotation for "always looking from the top" and "always looking from the side the part is on".
