(sorry off topic) You mention Touchscreen....While mine isn't as fun, and after trying the Rasberry Pi\Octopi, I have opted to use my Dell Venue 8 pro tablet with Repitier Host. I also have TeamViewer installed and also utilize Microsoft One drive. I can use the Touchscreen at the printer or remote into the Venue and adjust my slicer or printer temp/fan settings and even add a file to Onedrive from work and pick it up remotely on the printer and print. I'm still not comfortable printing while not at home but the few times I have I have been able to watch progress via TeamViewer on my Mobile phone and also watch my IP cam. I plan on doing an Arduino power strip so I can turn it on or off remotely. Perhaps Arduino actuated fire suppression is in line.
