Try downloading and using the software Flashprint. It is meat for printers with a dual extruder but it may work for your printer as well. When it is installed, go to supports on the top and click auto supports. This will automatically generate supports that will aid in the printing of overhangs. The controls on the side of the software let you rotate, move, cut, and do many other things. When you are finished, press print to select different options based on material, print speed, raft, etc. I hope this works for you.
