Filament residue from previous filament
Hi all,
I have started to have the prints with previous filament’s residues on some lines. It doesn’t end up after hours of printing, it occurs again suddenly.
I have recently changed the nozzle, I believe it is clean. I can’t make further assumptions. Appreciate for any advice.
Thanks

Do you have burned filament running down from the top of the heater block?
Make sure you use E3d nozzles (some cheap clones are a fraction too short) and pay particular attention to the diagrams at the bottom of this page:
