My retraction is set to 4.5mm and I can't figure out if I need to change it or not, but 2mm seems like a little too little to me, but I really don't know.

Hi guys,
believe me yesterday I spent about 8 hrs to figure out what's the cause of my poor printing and the result was quite scarce.
I tried to level the bed several times, I don't know if in the right way or not.
I used a flexible phone card to check the gap between the nozzle and the bed, moving it throughtout the area and doing fine tuning.
Probably it also overextrudes I have the E-Steps set at 95...
I don't know where to start/resume... the first layer piles up as a blob,
the nozzle at very beginning extrudes strands that I don't know where the h*ll they come from, morover hot nozzle ruins my works bumping over them.
I already tried retraction to 4.5 I have to give it a try again.
Suggestions are really accepted, even good words to heal frustation

You were right with the paper, but a normal sheet of printer paper is just the right height to allow for thermal expansion of the hotend.
Also, you should use Prusa's calculator to find the correct e steps you should be using. e steps aren't something you should really tune, but there is a definite number for any printer.

At 34C ambient temperature you sure had all windows open to catch a fresh breeze?
This might have been the cause for the warped handle.
If you want to print without heated bed, you´d build at least a casing around the printer.
Your other parts look better regarding retraction/stringing, but the cube still has "elephant´s foot".
Check this to see what´d help against it.
Keep the link as your 3D-bible

Yes windows were wide open but I have some doubts about the fresh breeze, it was quite hot here.
Anyway the printer was close enough to the window, so does light breeze affect printing?
Otherwise If I want to turn the heatbed on what will be a good temperature to set for PLA?
Take into account that today it's 32C 60% of humidity
About the elephant's foot you mentioned, I have to print such 20mm cube again , since yesterday before the wrech I leveled the bed again.
The guide you provided me with is very extensive, thanks man!
