Hi All,
I am new to 3d printing and I am just looking fr some advice, I have recently printed out testing cubes and believe I fount my optimum temps and flow.

Can someone please review the below images and suggest some alterations to fix the issues. Any more parameters required please let me know.

Machine: Reprap Prusa i 3
Flow: 101
Temp: 195
Filament: PLA
Retraction: yes
Retract speed: 45, 4.5mm
Supports: yes

Looks like the supports clasped in certain places which maybe the reason of some of the strings on the outer edge, also down the cylinder bore you can see blobs,

Thanks
