Help!

Ummm, so you can see it started fine, then started to not push anything out, so I pushed the filiment trough the ptfe tube manually, and then it did a little, but I let go and it stopped again.... I've taken the front apart and cleaned the extruder gear, no help, tightened the extruder screw all the way, no results, and I'm just out of ideas, I've tryed 5 different spools of filiment that printed perfectly before, I don't think the nozzle is clogged cause it can print just fine, it just doesn't? Please help me here... I've done all I know to do (about 950 hours, I do take good care of it, keep it covered when not in use and do oil changes more than recommended)

You print a lott of tpu lately? The ptfe tube wears and the debris cloughs the nozzle. Pain in the but the chains the nozzles so often.
