Cura 18 (lulzbot) will not install on Mint17.2/Ubuntu due to the lack of python-wxgtk3.0. It won’t even install if python-wxgtk3.0 is built and installed successfully from source. Presumably due to some naming issues for the .so’s.
Found a little error in the end GCode in the Beta. I noticed when I was slicing with the new Beta, that the bed would not turn off after presenting the print. I fixed it by updating the end Gcode from M140 S, to be M140 S0
