After numerous attempts to get RoboOS upgraded to Raspbian Stretch (Debian 9) I have decided to come at this from a different angle. I am going to sort of follow on some previous work (http://community.robo3d.com/index.php?threads/robo-flavored-raspberry-pi-octoprint.16942/) and see if the RoboOS can be streamlined a bit and extraneous files removed (There are two OctoPrints on the SD image, for example). At the same time, trying to reduce the dependence on Robo's GIT repositories and make sure all parts are up to date with current releases of everything on that µSD. I am going to start with Guysoft's Stretch version of Octopi as Octopi was the basis for RoboOS. That should give me a working base configuration allowing the R2 / C2 to fully function, minus the LCD screen. If anyone is interested in assisting me, I am not a very good Python coder, I would appreciate it. I will be creating a repository for the parts that need to be rewritten (not too much, as well as a place to store the rPi images. Since 4GB and 8GB µSD cards are nearly impossible to find in a Class 10 card I am going to build this as a 16GB image. This will require a 16GB or larger card to get working.
