I added PLA profile for Cura in github. It changes the temperature to 220 and start.gcode Type value to 1. Cura's profile settings are bit weird, apparently you need to load the profile you want to use every time you want to change it. I expected that loading a profile would add new machine... well I think the best option would be to add 2 machines in Cura, Cube ABS and Cube PLA and then load respective profiles to those machines
