What’s wrong here? Creality Ender 3 Pro

[Lilyvani]

Hi, I’m a newbie, first week of printing, with a brand new creality ender 3 pro. In this object I have lots of random supports that are failed and don’t really understand why, when the main support lattice is largely printing fine, there are these seemingly unnecessary extra ribs which are ragged and have loads of gaps. In the same vein, the very bottom of the object shows poor adhesion between lines and layers, can see the plate through it (still printing). Similarly some supports are only partially attached to their neighbours. I imagine this is basic stuff and would appreciate some tips.20200320_183757.zip
