(I have tightened motor shaft screw but could't solve this issue) 2) My print layer is shifting in X axis direction continuously , like each subsequent layer has a different starting point thus prolonging print along only X axis and only in one direction (+ve X axis). X axis and Y axis motors also become hot (I should say extremely hot) (My printer Please guide me in both issue.
