What’s the problem with this print?

[RedAlert]

I figured it out. That's where the layers start and stop. The best way to avoid it is to adjust the setting in the slider software to start the new layer closest to a certain coordinate.

For example in the print above, I set the starting point on X-axis to be middle of the bed, and y-axis to be middle / closer to the bottom. This way, all the layers start inside the model, at the bottom, and the outside perimeter looks great.
