First Layer Surface Sticks lines are visible

I have been looking for a solution to the problem as depicted. The issue seems to persist no matter the Z-height adjustment. These images are from the "bottom" surface. The side that touches the build plate. Any support on this issue will be greatly appreciated! I have not been able to locate online resources that have pointed me in the right direction yet.

These prints look like the First layer is too low.

I agree with Joan, those wavy patterns are tell-tale signs of a nozzle being too low. I use this calibration strip https://www.prusaprinters.org/prints/105404 to quickly dial my live z setting in.

Thank you, both. I will give this a try. I was adjusting the Z-axis between these prints with the built-in height adjustment tool. Perhaps I am still too low! I will report my findings later today.

Jeff Jordan's Life Adjust Z post appears to have resolved my issue and it was indeed too close by about 0.15...

I had to change filament to enact the change however. It appears that the cheapy BotFeeder filament that I have been testing on was water damaged (I can hear popping which corresponds to filament not being dispensed as seen in the holes of the black filament.)
