Do not over extrude filament when loading. As soon as the filament start protruding from the nozzle, stop. Loading any faster will cause the filament to get caught in extruder gear.

Feed the filament directly to the extruder, and not through the feeder tube. This reduces back tension in the filament as well as drag, ensuring proper feeding.
