Leveling issue maybe?

Hi everyone, I just purchased a TAZ 6, and I’m experiencing an issue with the finish of the part. At one end, the lines are nice and flat, and at the other end, there are gaps/ ridges in the finish. Would this pertain to a leveling issue? How would I go about fixing this? The filament is nGen if that helps.

As a first step I would recommend checking to make sure your X-Axis is level using this guide: https://ohai.lulzbot.com/project/leveling-x-axis/maintenance-repairs/
Sometimes the X-Axis can get shifted slightly during shipping, this can cause uneven first layers because the toolhead isn’t traveling across a flat plane.
Also did you notice any deflection of the corners of the bed during the autoleveling procedure?
