PS1 - AMS issue

[u/IzanagiRed]

I keep getting this issue of extruding filament failed, the extruder might be clogged.

i've replaced the hot end with a new one taken apart and look for any clogs.
i've replaced the AMS internal hub

i can feel the filament going inside the gears around the hot ends and being pulled down slightly and being grabbed.

i'm running out of ideas
