Arcs from .gcode seem to render with wrong clockwise direction for arcs ZX plane. Preview shows lots of weird circles instead of neat arcs, while tool tracking from G2 board (DUE) goes correctly. If G2 and G3 are swapped for ZX plane (by tweaks in tinyg.cps post) - the preview shows correct picture, BUT the weird circles appear in tool tracking.
In other words: G2/G3 interpretation of 3dviewer (GCodeParser object?) is different from tinyg for arcs in ZX plane.
