Hi. First thanks for reading this and for any help that comes from this post. Before any of you shits say it, yes I have tried tightening the 3 screws and drying my filament 😒. For added context I've worked in tech and have A LOT of debugging experience so believe me when I say I've tried damn near everything possible.

My printer stopped automatically extruding and idk what to do to fix it. When I send a print job, the filament gets fed into the hot end and then I get the error message that the extruder is clogged or the filament is stuck. The **ONLY** thing I can think of is the filament is misaligned when feeding from the extruder to the hot end. 

Here are my debugging notes

Learnings:

\>Filament successfully gets loaded into hopper. Filament gets detected as loaded, can be verified on display by green dot

\>Filament can be loaded into nozzle with the load/unload function >>Filament extrudes and purges as expected during this function

\> Filament can be manually extruded even when system throws error message of clogged/stuck filament

\>Filament will not extrude when a print is sent, even if material is pre-loaded using load function

\>>I'm able to print \~10% of the time omitting the AMS but system get into a feed, purge loop trying this bypass method

\>>>Loop is: system asks for filament to be loaded, filament loads, purges, cuts old filament, asks for filament to be loaded ♻️ 

What I have tried:

\>Physically pushing filament (at the AMS Lite end) with hands into hot end

\>Cleaning Extruder gear

\>Printing without using AMS, using EXT spool

\>Replacing nozzle

\>> waiting for system to give error message, cutting filament and then putting in a brand new nozzle

\>Trying other size nozzles

\>Downgrading firmware for A1 & AMS lite

\>Replacing hopper

\>Print part to hold hopper more upright

\>Using tool to manually extrude filament in nozzle to ensure no clogs

I have seen similar issues be resolved by pushing filament a bit; initially this was working but now it's not working. I'm at my wits end, I truly appreciate any help. The last 2 things I have thought to do are factory reset the printer (which IDK how that could help but I'm desperate) and also filing a ticket with Bambu.

Filament Extrusion issue, I'm at my wits end
