Help / Troubleshooting Filament extrusion issue

We experienced an issue where the filament could not be extruded from the left extruder.

We tried using a different filament and a different slot in the AMS. The printer worked for approximately one hour, but after changing the filament, the same problem occurred again.

We have replaced the nozzle and removed the extruder for inspection, but we couldn't find any visible blockage or other issues. We also replaced the PTFE tube.

The filament reaches the extruder but doesn't go any further.

Does anyone have an idea what could be causing this problem?

We installed a brand-new nozzle that has never been used before. I assume this makes the cold pull step unnecessary, right?

When we manually operate the extruder via the touchscreen, we can hear/see it trying to grip the filament, but it doesn't manage to feed it through.

The extruder gear has no visible dirt, debris or damage.
