I start to print and everything gets warmed up.
As soon as the temperature is right, 9-point-leveling starts.
Then printing starts.
o.k. and here is my problem: after a certain temperature has been reached, filament starts to extrude. Not very much but somehow constant. This filament is "pushed around" during the calibration process and most likely lands on the opject which is currently beeing printed; and messes up this print
Normally I then have to stop the print and start again.
How can I avoid this from happening?
What I am using:
- Prusa I3 MK3 (...)
- Slic3r PE
- PETG from dasFilament (I created a profile with reduced temp of 220 to prevent stringing)
What I do currently to prevent this from happening:
- Try to pre-heat and let it leak for minutes, than clean the hot nozzle and give it a try
