Ender-3 V3 SE adhesive problems

I am desperate!

I followed the instructions on the video: https://youtu.be/VtSVgwfsRpA

The print is PERFECT!

But

The moment I print a design, there is no adhesion and the filament end uo un a lot of strings as well as ‘n blob of plastic.

I use Cura 5.10.1 slicer with be build in settings of Sandard Queality.

I have the printer for a few months an printer secsesfulle until nou.

Thanks

Hello ! Can you check if the Z-offset you put is still being saved ?

Hi

The video is NOT for the V3 SE model, search out the correct one.

What temps are you printing at?

Correction: I did use the correct video and the file from the wiki page.

Tried the Creality print. One success, then failure again.

Newest problem: no heating. Just start printing - cold!

Should I use a 2 or 4 pound hammer?

My 8 year old Wanhao Mini (no heated bed, small and simple, manual bed levering) print better

I do all the automatic settings and savings… nothing! No difference.
