Flow stops after a minute.

[titanan]

Hey. My filament broke, and the print auto-stopped. When ? was replacing the filament, ? accidentally lovered the hot end, and thus, it scratched along the bed when ? resumed. When ? restarted, ? wasn't getting any filament after a minute of flow. I replaced the teflon tube and nozzle, but nothing changed. The extruder motor feels like it moves too easily but ?'m not sure if thats the couse of the problem. My printer is creality cr-10 v2. I really need your help. Thanks already!
