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

        Oh it’s a fantastic printer, but the default brass nozzles are $25 and the hardened steel are $53. Also you have to buy up to 5 of them at a time. Add to it, a 36cm^3 build area and you start to realize how fast the brass ones flatten their tips.

        In short, nozzles aren’t cheap.

        Thanks for coming to my ted talk.

            TBH, I hadn’t thought about it. But you’re right, I bet they are revos or something. Even then, those are still expensive. You aren’t buying a bag of 20 for $10

              It certainly depends on your hotend but I’m able to get a bag of 20 for <10€ for my trusty old ender 3 (actually 4.17€ on AliExpress)

              You could get the nextruder <> v6 adapter and then use the cheapos

                Maybe, I wonder how well the calibration would work for multi color printing then. Might be worth a test

          I’ve been printing for years on my original nozzle…do you guys just suck at calibration??? Admittedly I only print pla.

            Unnecessary aggression for sure but you can do better next time.

            I have a 3d design business. I’ve probably got thousands of print hours on my various printers. Some go non-stop for weeks. Brass is soft, it wears out.

            If you need me to take some caliper measurements of worn out nozzles and how it impacts a print, I’d be happy to educate you.
