The X/Y Axis motor is responsible for the movement of the extruder so if the extruder does not move at all along the guide rails, or it moves with difficulties making unusual noises and you notice shifted layers on your model, check if the short and long belts are tense and the screws on motor pulleys are tightened. See the manual – here. If axes maintenance does not help, the axis motor needs to be replaced.
