Method 3:
If the procedure described above has not led to success, heat up the extruder to the printing temperature (PLA = 230 °C, ABS = 270 °C).
Havetheprinterextrudesomelamentwhenthetemperatureisreached.
Then let the extruder cool off. For PLA to approx. 90-110 °C and for ABS to approx. 110-130 °C. The proper temperature depends greatly on
thelamentused.Youmayneedtorepeatthisprocessseveraltimeswithdifferenttemperatures.
Whenthetemperatureisreached,switchofftheprinterandpullthelamentquicklyoutupwardsbyhandandinonego.Attheend,theremust
be a small cone that corresponds to the inner shape of the nozzle.
Thismethodcanalsobeusedtoremovealllamentfromtheextruder,e.g.foraheatbedscan.
It is recommended to also wipe the nozzle a few times, e.g. with a paper towel, while cooling off.
