That’s true, but if at that time you were able to set up 2 different speed/power settings manually for two different materials, it would only stand to reason that you could do the same with Auto-detect Proofgrade materials as that is strictly the automation of loading speed/power settings. Unless of course there was a “slight of hand” in the video and the same speed/power settings were used for both cuts, letting the viewer take away from the video what they will.
Even though I have not seen the GF live at a Maker Faire, the short glimpses of the interface would seem to indicate you can setup any cut/engrave image any way you would like. That’s what it looks like from those short glimpses anyway. Seemed to be using that colour paradigm for cutting/engraving. Probably way wrong on all this. . .
Does beg the question on proof grade how the QR codes translates to various cuts/engraves. How could they know ahead of time anything but a cut action (other than vector cut all the way through) of for example a vector etch to partial depth of cut or any form of 3D raster engraving? Trying to visualize that one.
