I have a K2 Plus that is making knocking sounds when the print head is in motion and matches the rhythm of the print head. Has anyone else experienced this, if so, any ideas? I tightened all the Z rods, no avail.
When was the last time you cleaned and lubricated the tracks?
When you hear it are you printing on the left side . Probably the kabel holder of the extruder kabel thats touching the left side panel
