One thing I found is that when you are placing the extruder block back onto the motor, it's position can be different slightly, which will affect the grip the gear will apply.
What I would do is remove the motor and keep the extruder block on.
Whilst holding it in your hand get a strip of filament and push it through.
If it goes straight through without much resistance or if it wont go through or if it requires a lot of force to push through; then the extruder block is off slightly.
Just loosen the 2 screws holding the block and push the block to one side and screw it tight again.
Check the above and see how the resistance changes.
Then just keep changing it until the filament passes through easily but still requires a little bit of force to go through.
Whilst pushing the filament through you can also see how gear turns, again check this to get a position you think will work and then put back onto the printer and do a test.
