How long can last a feeder motor ?

[Odolyte 0]

Hi all,

I've got my UM2 for nearly 2 years now.

I've changed the feeder for https://www.youmagine.com/designs/alternative-um2-feeder-version-two

Wich is insanely awesome by the way...

Everything was fine until 2 months ago. I started having under extrusion. A lot of it.

I cleaned nozzle > nothing

i changed nozzle (with teflon block) > nothing

I changed feeder pressure > got worse

Changed temperature / speed etc. > nothing changed i had more or less under extrusion but still had some.

I used http://support.3dverkstan.se/article/23-a-visual-ultimaker-troubleshooting-guide

a lot but nothing solved it.

I still have my feeder motor slipping sometimes bringing under extrusion in my prints.

This brings me to ask the fatal question... everything coming to an end at some point, could it be my feeder motor that is too "old" and no longuer have the force to push my filament in ? and so should i need to replace it ?

Thanks for any feedback...

Pictures? Your motor current setting? Printed material? Filament diameter? Condition of the Bowden tube?
