Recently, my Ender 3 printer is giving these bad quality prints as shown in the image below. Something in common in all these bad prints is that they only fail in a particular section. The print looks good on the rest of the parts. I'm having trouble on how to find people with similar problems as I don't know what type of failure this is called. I would really appreciate any suggestions on how to fix this or if anyone experienced the same issue and managed to solve this.
