I own an Ender 3 Pro 3D printer. I'm having a problem where the nozzle pulls the already printed material along after 4 or 5 layers. The first few layers are perfect, but then the nozzle pulls the printed material along behind it. What can I do to fix this problem?

Hey, yesterday my HP Officejet 4620 printer bent the paper and got stuck, then I pulled the paper out and now it shows something about a paper jam and pulls the paper only for a short time and then no further. What should I do? If possible, I want to repair the printer and not…
Hello, the question is above Is from a HP 5520 Photosmart printer
This can have several causes.
First, the distance of the nozzle to the bed.
But even if the filament has drawn water, bubble formation occurs during heating. Impure surfaces can then be formed on which the nozzle remains suspended and the already printed tears along.
When the flux of the filament is too high, the excess filament swells somewhat high and the filament is also taken through the nozzle.
If the liability for any reason is insufficient, the pressure dissolves and is partially taken along.
4-5 layers are not yet high enough to cause warping for example ABS. But this can also happen. Then the corners usually stand out and are taken away from the nozzle at some point.
If the error occurs only in large areas, it can also be an uneven bed. Not every bed is really flat. That’s why many printers have the mesh option. In this case, the printer scans the pressure surface and notices the height differences. He then takes this into account when printing.
Enlarging the Z distance would be my first idea.
I tried at some point the distance was so large that kreise are no longer round but the nozzle still pulled the printed.
Then I would increase the next temperature of the nozzle and the bed, so that the material dissolves more easily from the nozzle and the adhesion on the bed becomes better.
I’ve done nothing changed
Then I would go to the race with 210 or 220°C and 60 °C bed.

Which manufacturer?
Use PLA
which temperatures would you recommend?
Increase the pressure temperature. Could be that the filament is still too cool and therefore not properly adheres to the pressure
I print 200 C how high would you recommend?
What material?
Look at the filament the specified pressure temperatures. If there is 200-220, take 220 so the highest
