My Printer only has around 20 hours on it and when it is printing there is a knocking noise as the extruder head moves back and forth on the x and y axis. Sometimes it doesn’t do it at all and other times the noise happens every time the head moves from one direction to the other. Has anyone experienced this? If so is how do I fix this problem ?
Are you able to record any video, please? It would be helpful. For the time being - lubricate the rods and check the extruder’s movement when the printer is turned off. You should not feel any resistance.
