Cleaning the nozzle

  • Heat the noozle to medium temperature of the material in the nozzle.
  • With low extruder speed (<24RPM) try to press material out
    when material blocks, remove material with low negative extruder speed and cut off 20mm of material that the material gets grip again.
  • Repeat this 5x to 10x until material flows out of the nozzle again
  • If you are not sucessfull, cool down the nozzle and disassemble it.
  • Drill out the material with a 3mm drill (2.5-3.0) as deep as you can go with a standard drill
  • Reassemble the nozzle and repeat the topics above
  • It is very unusual that the small hole in the nozzle is blocked and you can not get an material flow with the hints from above!
  • If you can ot get a reflow of material, use a thin wire (<0,3mm) to clean the small bore in the nozzle
