Someone printing an object had an issue where the printhead would move off to one side after each layer. This can be set by several slicer settings. You can enable/disable, depending on what you are trying to do.

Most slicers have a camera setting. After each layer the printhead moves off to the side to give a clear shot of the progress for the camera. 

Minimum layer time. For small cross-section prints, you can run into issues if you print too many layers on top of each other too quickly. Minimum layer time moves the print head off to the side for a moment to allow the last layer to cool down a little bit before moving on to the next one.
