The extruder clogged up, and already arranged additional heating with a building hair dryer - it was not possible to break through.

Under the microscope - it turned out there was metal shavings . I polished a thin sewing needle with a diamond disk on a
dremel to the size of a nozzle, cleaned it from the back side while heating both the needle and the extruder with a building hair dryer.
