Patchy print

Kind of looks like nozzle clogging. Changing the nozzle was my go to first move.

is it possible to have a clog above the nozzle? it is touh to push the filament through to the nozzle at times

[Ian Davlin The Looth Group]

it is, it’s called heat creep I think

[Anthony Kreher Kreher Guitars]

Hey @ianhatesguitars so I got the clog out of the throat I got the whole hot end assembly as clean as the day it was in the factory! Everything COMPLETLY free of pla. Was feeling pretty good. But still the same bullshit. It’s not a clog. What is up with the extruder here. It doesn’t seem like the little brass cog is worn out or full of plastic. I can’t take it off at the moment tho. The one set screw I stripped. Need to get a tiny ez out and a new screw. But that’s all I can think of! Ahhhhhhhhhhh!!!

I will send you a video too. Won’t upload herez

Could be your extruder is slipping. I upgraded that on my 3 as per Ted’s recommendation. Not sure if the plastic parts on yours are the same as on the 3pro, but the 3pro shipped with some rookie bullshit.

Ok i believe i have diagnosed the two fold problem. First, in my research this moring i stumbled upon some interesting information. I had the hot end taken apart yesterday to clesn it out. i did NOT put it back together correctly. I didnt push the bowden tube down enough and it was far from seated properely on the nozzle. That was a recipe for destruction.

The other problem is the extruder. Not entirely sure what it is but i did find that when i give the lever a little hand tension it works fine. So i pulled the spring out and streched it a bit. Its almost done with a whole test print now. Looking pretty fine (one wall isnt adhered good. whats up with that? cooling problem?) I ended up placing an order for some goodies. An EZ out to take out the set screw that is stripped and holding on the extruder wheel, and a micro-swiss bowden dual gear extruder. that should really fix things on that end. I hate when something goes haywire with this thing. But i have the drive to fix it. from what the internet says, seems like most people let it sit around a few months before they deal with it.

Good info. I have the Micro Swiss NG hotend/extruder on mine. It is really nice.
