The X/Y axis motor is responsible for the extruder’s movement along the guide rails. Therefore, if the extruder in your printer does not move at all or it moves with difficulties and makes unusual noises, or your models has shifted layers, at first you should check if the short and long belts are tense and the screws on the motor pulley and axes pulleys are tightened. More instructions on maintenance work connected with axes can be found in this article. If carrying out maintenance work does not help, the X/Y axis motor needs to be replaced. Follow the steps from this manual to replace the motor.
