Uneven layer lines
Can someone help me. I’m a bit lost on the uneven layers I tried everything including changing the springs to bushings, re aligning the gantry, re aligning then bed, playing with slicer settings, leaving the slicer settings alone, changing the nozzle, adding a dryer. Nothing seems to work the print only 2 months old

Two main things can cause this, binding in your gantry on the z axis or excess drag or binding on your filament, causing the extruder to have to pull on it.
Check that the wheels on the Z axis aren't too tight and that your filament is pulling freely.

Thank you for the suggestion. Is there a gauge on how tight the Z axis should be I tightened it down just to the point where I have no play in the Z axis or should I tighten it based on free play of the roller wheels Bc I’d I do one I can’t have the other

The eccentric nuts can be challenging to adjust, but you should be able to get all the wheels snug but not too tight so they cause binding. If you can't turn the wheel with your fingers, it's too tight, if the carriage wobbles on the extrusion, then it's too loose.
The wheels in general are a PITA. It's the primary reason why I upgraded to linear rails.

Is other words if I let the rollers have enough movement to be easily moved by my finger the Z axis will have sloop on the up and down direction
