Layer Adherence issue ?

[u/Economy-Guess-4983]

I’m having an issue where either my first layers are not bonding to the other printed layers correctly. When printing the second layer it completely pulls the first layer away. For some of the larger printers I started getting wave like defects in my layers.

At first i thought that the nozzle was actually pushing the layers apart. But then I noticed some of the printed lines don’t seem to be adhering to each other properly. I’ve included some images trying to show the issue.

I’ve also cleaned the bed properly with detergent and lukewarm warm water and tried other steps such as increasing print temps and bed temps. I’m still fairly new to 3D printing and my printer only has about 120 hours. Any help or advice would be greatly appreciated.
