PSA: Maybe don't buy these shitty extruders
(m.media-amazon.com)
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.
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?
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
