MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
But I have not tested it on the printer yet, or with a webcam. I doubt it will have any problems though, my official Rpi 7" seems to work OK with a webcam. I think it is a good idea either way to avoid using the touchscreen when printing though (not entirely, but just being careful). Below is a screencap from when I was bouncing though the menus on TouchUI (intentionally trying to spike the CPU).
It works :)
