Anyone running Rpi & printer board?

Anyone running Rpi & printer board? Experience any problems with the printrbot stopping half way through a job? Other issues?
I have an rpi lapdock setup running slic3r & prontrface driving my printrbot lc. Works fine (but sloooooooow) for the most part but it fails printing things like the nautilus gears.

Any recommendations on rpi setups that will free up my laptop once it’s done slicing (slic3r on rpi is too slow) e.g automated gcode file transfer and kicking off prontrface, how would you do that? What’s you rpi setup? Would it be too much to ask the rpi to run a webcam watching a print on top of prontrface?

That’s exactly what I need, thanks!
