Anycubic Kossel printer extruding issues

Any filament that I insert into the hot end and try to extrude just ends up be coming deformed and essentially clogs the hotend. I only have used PLA filament, and I have tried changing the nozzle. I took apart the entire hotend and saw no blockages of anything kind that obstructed the filament from passing through the hotend. But when i try to extude the filament using “Pronterface” it only results in the deformed filament.
