/**
*
* @author Thomas Oster <thomas.oster@rwth-aachen.de>
+ *
+ *
+ * some technical details about the iModela IM-01:
+ * max. part dimensions (x,y,z): (86mm, 55mm, 26mm)
+ * operating speed x and y axis: 6 to 240 mm/min
+ * operating speed z axis: 6 to 180 mm/min
+ * software resolution: 0.001mm/step (in NC-code mode), 0.01mm/step (RML-1 mode)
+ * mechanical resolution: 0.000186mm/step
+ *
+ * This driver controls the mill using NC codes.
+ * Reference: http://icreate.rolanddg.com/iModela/download/dl/manual/NC_CODE_EN.pdf
+ *
+ * Currently, this driver just engraves/cuts material in 2D. 2.5D data is not supported by VisiCut (yet).
+ *
