Horizontal Banding on prints

[Project_Edan]

Dudes and dudettes, I am at my wits end trying to get rid of this issue. Across all of my prints, regardless of nozzle type, i’m suffering with these lightened horizontal bands.

THINGS I’VE TRIED:

• Altering speed of outer walls
• Switching Nozzle
• Different build plates
• Adjusting Z-Hop
• Swapped out entire Z-axis/Gantry
• Altered position and support for printer numerous times
• Changed extruder and cleaned its gear
• re-tensioned belts and lubricated appropriate sections
• new Z-axis tensioner
• new hot-end (and tightened the 7 infamous screws)
• new toolhead block
• new part cooling fan
• multiple re-calibrations
• with/without AMS Lite

I can’t seem to solve it at all. Haven’t a clue what else to do. It’s worth mentioning that alongside these bands, layer lines are also more visible on prints these days. WTF?

Same for me look at this pics.
For me it’s a bad design on A1 printers without coupler on z axis !

Can we see the slicer preview of this part? No idea what it’s supposed to look like.

The intention is for it to look exactly as it already does, but without the lightened horizontal bands repeating up the model. It’s the leg of a statue. It happens on every print of every model.
