Filament keeps breaking

[edwardreed]

I have a creality ender 3 pro. I use creality pla+ filament. It breaks right at the Extruder. It breaks between the pulley and the gear on the stepper motor. it is the original setup from the factory. The only thing that i change was the hotend and that was a year ago. it looks like the filament is grind in half. It will work good for one print and then the next print it will break off. I check everything and it looks good. I even tighten the screw to make it tighter. thanks for the help i get.
