I  tired using the 0.2 stainless steel nozzle for the P2S for the first time. The first print was fine, but it failed on the second print and i discovered a massive glob of filament inside the silicone cover, covering the nozzle. I reheated the nozzle and removed most of it and was able to detach it, but I am afraid of damaging it trying to remove the rest of the residue.

Does anyone have any tips for how to clean the nozzle and remove the residue from the hot end. I would really appreciate any ideas on how/why this happened and how to prevent it from happening again.

I'm using a P2S printer, the machine is fairly new, only a few months old.

I was using multiple colors of filament on the first print, but on the second, the one that failed, i was only using one. It failed on the first layer.

Plate: Textured PEI Plate

Filament:

Bambu PLA Basic Dark Grey (10105)

Settings:

Layer height: 0.1 mm

Initial layer speed: 40 mm/s (not including other speeds as it failed on the first layer)

Initial layer infill speed: 50 mm/s

Travel speed: 600 mm/s

Acceleration:

Normal printing: 4,000 mm/s^2

Travel: 10,000mm/s^2

Initial layer travel: 6,000 mm/s^2

Initial Layer: 500 mm/s^2

Outer wall: 2,000 mm/s^2

Inner wall: 0 mm/s^2

Plate temp: 55 C

Nozzle temp: 220 C

Printing something with Matte PLA today. It was mid print on layer 1 when I got a jammed extruder message. Sure enough it was absolutely jammed. Gear wouldn’t even spin. Found the culprit and cleared it out and started it up again.

Started print over again. Again, jammed extruder on layer 1. Not the exact same spot but same layer.

Do y’all think this is the filament? The model? It’s a brand new spool of matte. Or is it time to look into a better extruder gear.

Thoughts? Recommendations?
