# Experiencing Under-Extrusion and Print Instability on CReality CR6 SE with Various PLA Filaments

(Asked by: username_0 on 2023-12-12)

I am facing persistent issues with under-extrusion and print instability on my Creality CR6 SE 3D printer. Despite using different PLA filaments from various manufacturers such as Eryone, Jayo, Prusament, Redline, and Amazon Basic, I consistently encounter problems with thin lines and unreliable prints.

Notably, the same filaments perform well on my Prusa Mini, ruling out filament quality as the sole culprit.

[![enter image description here](https://i.sstatic.net/6EMS2.jpg)](https://i.sstatic.net/6EMS2.jpg)

Here are the key details:

* Running the latest Community Firmware.
* PLA filaments are stored adequately, ranging from a few weeks to several years old.
* Hotend temperature settings range from 205-215 °C with a 60 °C heated bed.
* Standard settings slightly modified for wider inner perimeters (0.6 mm) and higher temperature for stability.
* Occasional difficulties during filament changes, even with the extruder released and the nozzle adequately heated.

I have performed some troubleshooting steps, including changing filaments, adjusting Z offset, and ensuring proper storage conditions. However, the issue persists. I also cleaned the extruder. Could it helb to replace the PTFE tube with a Capricorn tube?

Are there additional steps I should consider or specific settings that could be impacting my print quality? Any insights or guidance would be greatly appreciated.

Try following [a guide on debugging under-extrusion](https://all3dp.com/2/under-extrusion-3d-printing-all-you-need-to-know/) all the way through.

The most obvious point you did not list in your question are: checking the mechanics of the extruder and cleaning the nozzle:

* Making sure the extruder gear theeth are clean and sharp
* Ensure proper spring tension is pressing the filament to the extruder gear
* Check if the motor has enough force/current to push the filament through your fingers if you press them together
* Calibrate the E-Steps
* Check that volumetric E is not enabled in your slicer settings.
* Make sure you can manually push filament through the heated nozzle without too much force
* Perform a cold pull or several
* etc.
