*
* 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).
