Collecting filament at the HF nozzle
Dear all
I upgraded my MK4 to MK4S with HF nozzle.
Now I have print failure. There is molten filament collects at the nozzle. And from time to time this filament sicks at the print. When the print head comes back to this point, it stucks and tear the print off.
I use the standard profile of the filament and I tried it with prusament PETG and with extrudr PETG. At both filament I got fimamentcollecting at the nozzle.
Is there anybody with the same problem or has anybody an idea to solve the problem?
Thank you

Sounds to me like a defective nozzle
l did the same upgrade and have had nothing but great prints

RE: Collecting filament at the HF nozzle
PETG is super sticky and nozzle buildup is not uncommon, however it's typically made much worse by wet filament.
Id recommend drying your filament, and making sure your nozzle is clean at the start of the print when it does bed probing.
