@Dimitris_Prokos The movement is caused by the x axis, however you cannot see it in a signal layer as it is probably .05mm or less per event. However this error compounds and as you move up in the Z axis you can start to see the distance add up.

Edit ( it is almost impossible for this type of movement to occur in the z axis without the device falling apart)

Is your bed absolutely flat, relative to the print head?
You can spot this by putting the head on Z=0 in each of the extreme X/Z corners.
Should be same distance from bed.
