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.
I have a Monoprice mini select V1 that I still use occasionally. It has a terrible extruder on it that can’t handle anything. I put a better hot end on it and it runs much better.
I did the hot end because there are no aftermarket nozzles for the V1 Monoprice hot end that I’m aware of. Anyways, the better heating of the filament made the extruder skip less.
It won’t make it amazing, but if you find a knockoff CHT nozzle for the printer. More efficient heating might flow more easily, reducing the pressure on the filament that the extruder has to overcome.
