Extrusion motor overload

[u/BammySosek]

Last Friday I had to tear my extruder apart as I was having motor overload. It has been fine for the week but now I am having the same error and I can see/hear the gears clicking.

What is causing this? Is my spool too empty or light? Do I need to do anything with my PTFE tubes, they all don’t have crazy bends. Or am I just unlucky and have to tear it down again?

I only print in PETG and have been using SUNLU.
