Print Core Lifetime

[Felix11042000 0]

Hi everyone, 

 

I am having some issues with underextrusion on the ultimaker S5. The print core I am using has 4500 hours of operation. What is the average lifetime of the cores? I know it depends on the materials and temperatures used. But I have no idea about the average lifetime. Should I get new ones?

They don't really have a fixed life span, as you noted it depends on many factors.
Often issues with under extrusion can be addressed by cleaning the core

Outside of that often under extrusion can be due to bad settings in UltiMaker Cura or even simply a dirty front fan on the print head
