There are four option for us to choose in different situation.
Random
The Random seam position technique aims to choose a different point for each layer as the seam location. This reduces the visibility of the seam but may result in a less smooth surface with small zits scattered across it. When printing cylindrical shapes without sharp edges, the Random seam position technique can be a suitable option to minimize the seam's visibility.
Nearest
If the Nearest option is selected, the printer attempts to choose the nearest edge position for each layer as the seam location.This minimizes the seam's visibility, especially in situations where there are edges.
Aligned
The Aligned option follows a similar logic to the Nearest option when determining candidates for the seam location. However,the Aligned option prefers the candidate whose position is nearest to the seam in the last layer.This alignment makes the seam appear more continuous and less noticeable.
Rear
The Rear option follows a similar logic to the other options when determining candidates for the seam location. However,it prefers candidates whose position reaches the maximum Y-axis value.This positioning makes the seam more likely to appear at the back of the model, making it less noticeable.
