That won't fly Roland. 2 reasons. I forgot to turn one over before I ran lightscribe, and it knew the disk was upside down. And to do that, we would need a working cut-sim to convert our gcode to an image format (png?) lightscribe accepts. My little fishing expedition into that over the last 24 hours seems to have disclosed that none of the trails I followed have led to working code, the closest I got was openscam which I had to build, but then fails to do anything useful, and that the best 'preview' of what I want to do is likely to be obtained by making it out of a cd & perhaps a coat of black paint. All this could be satisfied by my proposed additional field in the tooltable that would enable, perhaps as a preview only translation as the code loads, which would turn the backtrace plot into a great preview by utilizing the selected tools diameter as the width of the path to trace, perhaps even using a different color for each tool size, as opposed to the current 1 pixel wide wire frame of the tools center line path. I can see where this is certainly not a run time option for obvious video horsepower needed reasons, not to mention the video memory required. Other than loading time growing by 500x for the preview only render, it would still be cheaper than the worn tooling and materiel cut up only to find there isn't room enough to make it work that way. To my train of thought, even the cut-sim approach, which might be theoretically correct, seems like patently the wrong approach when just translating the gcode into a brush the width of the tools diameter and then tracing out the XY motions only where Z is negative, would do a quite decent job of rendering a 2D preview. Heck, even a plugin for gimp would help, but we are I think predisposed to want to see that in the axis backplot window so we also can see the zoomable image with a measurement scale. The utility value of such an option was why I asked. Perhaps this is something that none of the other competing high dollar stuff like mach etc can do? I have never seen Mach other than as thumbnails of its screen so I can't write about it. Thinking that freecad may have grown an import gcode function, I even put my machine on the daily build list for that, but it seems not, the open menu has the import/export functions greyed out until a legit file has been loaded. I did note that the docs for freecad have grown until they are 2x the size of the freecad package itself, so this alone will put it on many more machines. Great progress in a year or so IMO.
