So you have re-leveled and still get the same result?  When you say it doesn't stick does that mean anywhere on the bed or just in some spots?

 

If you re-level and get the same result as the picture then try moving/rotating the glass 180 degrees and see if anything changes.  See if you get the low spot in the same place or if it moves.  Might be a warp in the glass.

 

Also try turning the model on the bed (in the slicer) by 90 or 180 degrees and see if anything changes.

it always occurs on the back in the middle (the not sticking)

and this filament pressured mostly on the left as you can see above

Hi, if your issue happens only on one side of your print it means you need to level your bed better.

For your filament not sticking if you leave more space, you need better bed adhesion.

There are several tricks for that: raise a bit your hotend and/or your bed (if heated) temperature (5 or 10 degrees usually works best without bringing other issues).

You can also slow down your first layer.

what i meant by not sticking when the bed is a little lower, the nozzle simply doesnt touch the bed sometimes

Ok so you definitely need to level your bed.

It needs to be flat and level.

I don't know your printer but you can usually change its angle with screws or similar.

well, i will do what you said once more, maybe i did it wrong in the meantime but i tried it before and it simply either did not stick to bed or made the result showed above
i will write again with the results of this
