I would suggest printing an auto leveling setup early on if you dont want to deal with bed leveling.

As to you connection to the printer I would try different USB ports on the computer as well as a new cable


As far as the ABS i would suggest using a pretty high print bed temp around 120 especially if you don't have an enclosure, the slightest breeze can warp the print.
The auto leveling is something I want to do but Collin told once setup correctly it shouldn't be needed. I can't even get it setup! Hopefully the Rumba is capable of auto leveling as every thing I read seems to be ramps. Wish I could do ABL, but I can't even print the parts!
