Prints Fail at 80%

[Ronniestone 0]

Hi all,

 

Ive been having odd sudden issues with my printer. I have the Ender 3 and I was getting the dreaded Clunking noise, I eventually solved it by raising the nozzle temp. My prints were also very stringy, Ive tried all sorts of adjustments but cant get my prints back to normal.

 

Please see photo of the results I am getting.

 

Any help will be greatly appreciated.

Do the exact same gcode files that you printed before now fail? Because if so the problem is almost certainly with the printer.

 

I thought the "clunking" noise was generally related to the extruder, so raising the nozzle temperature would only be a stopgap measure which makes it easier for the extruder to feed filament through (but is generally a bad idea because materials are designed to be printed at certain temperatures).

 

Stringing also strongly suggests a problem with the extruder, unless it coincided with you changing the retraction settings (but then your problems would likely be limited to the stringing anyway), especially if it's with an easy to print filament like PLA (stringing with PETG or TPU is "status quo").
