Cura is generating unecessary supports

[panakon 0]

Hello, I am new to 3d printing and i tried to print this part to upgrade my Anet A8 but when I select generate support , it generates those weird support stuctures that doesn't seem to support anything.

I tried to find the setting to disable it and generate only the supports that I need but I coudn't find it, so I printed it. The cylinder, right one , was inside a hole and was a nightmare to remove and I almost damaged the part trying to pill it out. I'd like to reprint the part but first I need to disable these small supports. I really try to understand how the software works and what setting should I use for each part as as of now I find it really enjoyable but this really messes with my head. 

If you have any idea of what is causing this or a way to work around it, I'd be very thankfull.

If you turn the right side in this image to be down you might not need any support.  Not sure - I need to see the part better from all angles.

 

I usually just create my own custom support in CAD if cura doesn't figure it out right away but there are tons of settings you can play with - maybe the x/y wall distance is the one you want?

Try lowering be the support join distance and the support horizontal expansion.

how do you control where the supports are placed?  It's so difficult to remove them and I feel that I can minimize them using Tree supports.  Im new to 3d printing, but my hands are all cut up and I have had to throw away too many projects from damaging them removing supports.

To my expirience so far, using 1 line wall  support seems to be easy enough to remove. Im new to this too though and I don't know if this is enough for bigger prints or if are there any other options.
