Strange Noise when Homing

This is usually a mechanical issue, caused by friction between limit switch. Try the following things to help with this issue.

  • Adjust the distance

There is a screw used for hitting the X-limit switch. If the screw is too short, it can hardly hit the switch. You can loosen it a little manually.

  • Keep the axis lubricated.

After loosen the screw and applied the lubricant, try moving the extruder with your hand and see if the noise is gone. If not, limit switch may be not working properly. Contact us for further instruction.
