NCPlot 1.1 FREEWARE replacement PlanetCNC USB Controller software

The defunct NC Plot v1.1 FREEWARE cnc backplotter is replaced by PlanetCNC USB Controller software. This software provides excellent gcode simulation as part of it's featureset.

Backplot runs automatically (F12), by  scroll-keys, or  by scroll-bar.  View pan, tilt and zoom are available AS the simulation runs. After a little setup, it handled 300,000 lines of 5-Axis surfacing code no problem. Some suggested settings are in the cnc4free.org forum  'Updates' thread.

A software license and USB hardware are required to run a CNC machine.  Simulation, toolpathing and 'translation' functions, like image to gcode, .DXF to gcode, and many others, are 'unrestricted'.  This is confirmed by Andrej,  the author of the software.
