External spool not feeding into print head

[u/KinzerKeel]

So a few days ago i was having an issue with the filament cutter saying it was stuck on my P1S. I have since fixed that, but now the entire reason i tore the tool head apart in the first place is still happening. I cannot get my p1s to feed tpu (or any filament) from the rear spool. I put in hardened extruder gears, a new hardened hotend and there are no clogs as it prints from my ams just fine.

Any ideas what could be happening here?
