In Cura, go to the top bar - Click expert, Open expert settings. On the right hand side under supports you can change your supports from grid to LINES which always remove easier. Then look down to distance z and bump it up to .2 but be aware this may affect your clean edges a bit. If using a raft, you can increase the air gap there as well. It is clearly labeled as Air Gap under the Raft settings. If struggling with raft removal you can also try turning your fan on earlier (say at layer 2 or so).
Here is a great reference for quick trouble shooting using Cura. Some of it is Ultimaker specific but still may be useful.
Also, I am really impressed with the helpful tips from Matter Hackers. I LOVE using Matter Control (under configuration you can choose to use their slicing engine, Cura, or Slic3r so that’s pretty cool). Also, Lars is really knowledgable, responsive and helpful. Printing with a Raft | MatterHackers
I hear really great things about Simplify 3D but I like to go the freeware or open source route since mostly I am teaching others and prefer to make things as accessible as possible. Let me know if that is helpful or if you have other questions.
