I am running an S5 with the material station. All of a sudden after just simple maintenance like cleaning and lubing guide rods, my printer is being stupid. I keep getting ER65 notices about 20mins in to any print. I have cleaned the entire machine top to bottom. Including opening the material station and cleaning every single tube. Also, the extruders and every other little thing. Still the same thing...ER65! Someone please help?!
