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.

Cleaning the printing plate
