3V3 Plus, clicking noise in extruder

[cbrake]

We have had our Ender 3v3 Plus since January with no major issues.

Recently, however, it started making clicking noises during prints and extruding erratically. We have taken it apart, inspected the extruder gears, and cleaned the nozzle multiple times, but nothing seems to help.

We thought the nozzle might not be getting up to temperature, so we put on a few thermocouples, and they seemed to indicate that nozzle temp may be low.

Is this a possibility? If so, what are the next steps, or are there other things we should be looking at?

Thanks!

I experienced clicking near the feeding tube and Bowden gears. I simply cleared the filament recut it and reinserted the filament. For me the clicking was because the filament was not feeding properly into the extruder.

To be sure change out the filament with a different manufacturer and see if it’s filament inconsistency.
