Ender 3 pro bad printing

[vykeymasmaya 0]

I am getting this kind of issues when printing. Printing is not good and I have used super quality settings in the cura software. Need help to get rid of this problem. Kindly let me know how to solve the issue.

...it's hard to tell what the exact problem is by watching at the photographs... please attach the project-file so we can see you printer and cura settings...

 

Did you manage to get a good print with one of the other profiles?

I had the same because of Bowden tube. It swelled due to high temperature.

It can also be:

- gap between nozzle and Bowden tube 

- too much retraction distance

- nozzle clogged

Yes, severely under-extruded.

The Extruder steps/mm may need calibration.

The printer and/or Cura have been set to Volumetric extrusion.

As @brtzor says, it could be a problem with the printer.

Both Mari and I have Ender 3 Pro's.  For myself it was always a blocked bowden tube at the hot end from heat creep.  I finally gave up and went with an all metal hot end.  Not perfect, but it's much much better.
