That's not the software or the PEI plate. ABS is very sensitive to temperature differentials, even a cool breeze from opening a door can be enough to set it off. On my Delta I would put a big heavy plastic bag over it, that was usually enough to protect it from drafts and let it print higher without problems. Until I did that I screwed up more than one ABS print by opening the door to let the dogs out. Have not tried ABS on the Robo just yet.
