Printing issue with flat surfaces

[Baltazar]

Hi all. When i am printing something flat usually at the top i have some line gaps. However when i print something small i have no issues. Any idea why that happens?I add a link to one of my prints to understand my issue. I use ender 3 and Cura 4.5.6.
Thanks

This could be due to a verity of factors. Is this a stock Ender 3?
Can let us know your Cura settings, screenshots would be best. Also what filament are you using?

I have the following upgs. E3 SKR mini 1.2, BLTouch V1.3, the creality glass bed. Specific print is with eSunPLA+. My Cura settings are the ones recently uploaded from Chep for 4.5.6. I used the one which Chep named it best quality.
However the specific issue i had it also before the upgrades for similar surfaces and with previous Cura versions.
Thanks

Do you still have the stock extruded bracket? Does the printer make any clicking noises on those long passes?

Thanks gigobait. Sorry forgot to mention that i have changed the plastic with the metal extruder. I do not hear any clicking noise.

Also my bad. The profile i used from chep was not 4.5.6. Was 4.6!
