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.
Why did you want to originally replace the extruder on your ender 3? I've only been running mine for ~100h now, so I haven't yet figured why one would need to change it. Did yours just break?
Over 200h now. I rack up hours printing parts with 100% infill as they get annealed in the oven. Time will tell when I get issues. So far I've had to retighten the x axis belt once, but no other issues.
I get that the original plastic tension arms break after a while, but I hope that the metal arm on the neo will last longer. Can the softer extrusion gears be replaced with steel or some other stronger material?
Crap, I bought one of these and it worked well for a few months, but now my printer has been under extruding for a while and I couldn't figure out why. Do you have a better recommendation?
