Do you still have the stock plastic extruder? The stock pressure arms are very prone to breaking (see the image below). Take it off and look at the underside of the arm. Under-extrusion can be mistaken for poor bed adhesion or a bad leveling job as all three cause insufficient squish to the build plate.
I can't see an ABL in the images...have you changed the way you are leveling?
Are you using anything to aid bed adhesion (glue-stick, hairspray, etc.)?
The bed looks clean. Have you given it a good wipe down with isopropyl alcohol lately?
Here is the underside of a stock Ender 3 pressure arm. Some were delivered like this.

Thanks for the reply!
Yes i still have the stock plastic extruder, i just did remove the arm and no crack found under it, and there's no abl installed, I manually level my bed.. i don't use glue stick or anything but i always wipe the bed with alcohol before each print... I understand that everything point to a bed adhesion problem.. but at the same time why would the wall that print constant (without retraction) get perfect adhesion?
I will try a test print with gluestick on the bed to see if it helps
The full stable release of UltiMaker Cura 5.4 is here and it makes it easier than ever to remove brims and supports from your finished prints. UltiMaker S series users can also look forward to print profiles for our newest UltiMaker PET CF composite material!
