Need Advice: carbon fiber print problem

Hi, everyone!

This is my problem: When the printer starts printing it stop extruding. The filament stops. But it´s not due to obstruction or because the extruder has stopped.

I have already tried this:

  • Clear the extruder and the nozzle
  • Reduce printing speed (to 54 mm/s)
  • Check that there´s no nozzle obstruction
  • Adjust bed leveling and Z-set
  • Adjust the extruder screw
  • Check that the extruder isn´t worn
  • Adjust the temperature (220°C)

What else can I do? Please… Help!!

Thanks Thanks Thanks

NOTE: I am using a Dowell 3D printer with a stainless steel nozzle (1.6) and I am new
