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.
They can, but really it’s not even worth it with those things, you can get cheap bag or titan extruder knockoffs on Ali- express that are a million times better. One of my Enders has a cheap titan direct drive kit and it’s actually awesome. I think I paid 35 bucks for it. And the knock off came with dual gear hardened steel gears. Triangle labs makes a killer bmg clone as well
