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’m glad it is working well for you.
I’m probably gonna print a mount for it to make it a direct drive extruder, but for now I am just so glad that it works at all that I kinda want to print other things for the time being. It’s been almost 8 months since I last had it working.
