I spent entirely way too much time trying to get one of these style extruders on my Ender 3. Maybe I picked a knock off without realizing it, maybe mine was just defective, I’m not entirely sure.
But it was ultimately the cause for my printer underextruding on certain layers. If you need a new extruder, go for something better than these cheap $20 ones and get an actually decent one.
But on the bright side, my printer is finally fixed! It feels nice to be able to get back into the hobby again.
A good solid extruder if you are willing to build it yourself (and want/need bowden), I can recommend the Voron M4 extruder.
Do you know if that can be printed in PETG?
I always saw recommendations to use ABS and I really don’t want to print that stuff
Of you don’t use it in an enclosure, yes, PETG is ok.
