Back in December I got my P1S and since I mostly printed Vases and plant pots back then, I decided to mostly use PETG.

That PETG as I now know was just Wet, which caused it to ooze out of the nozzle after the print, a Fact I hated. Since at the time I must’ve be pretty stupid, I decided to clean it by Heating the Nozzle to the max of 300°C and let it ooze fully out. It did work and the prints after it where fine… so I did it another 10-20 times until I got a Brass Brush and started just using that…

In retrospective, Filament really shouldn’t be heated over its limit… because that probably Backed in the PETG really hard. Mustve been to the point where the nozzle clogged, getting me to cold pull it a lot.

Big question is, is there still Backed in PETG in that nozzle, even after 20 or so Cold Pulls? It definetly seems to underextrude a noticable bit. Should I use the replacement nozzle or look into other reasons for said Underextrusion? Thanks!

Edit: Did as suggested and tried swapping the nozzle, thermistor was stuck and getting it out broke it, replacement thermistor is gonna take till thursday to arrive, god I hate this machine

    It is a stainless steel nozzle, but the real problem is that it’s not just the nozzle, it’s either “hotend” with cooling ribs etc, with lots of fiddling to connect wires etc, or “complete hotend” that also comes with a fan so more of the wires are already connected.

    I wish they did like Prusa where you can also buy assembly, but they have one that is basically an adapter so you can use any regular cheap nozzle.
