Layer Shift or Layer misalignment

If you identify a “stepping” effect in your print, this is called layer shift or layer misalignment. Most common 3D printer don´t have a feedback system, about the actual position of their toolhead/hotend. If there is an impact during the print or a motor loses steps, the printer cannot detect this and will continue the print with a wrong position.The following solutions are a good way to solve this problem, but it can also be caused by warping upper layers.
