Kossel mini extruder ticking sound

Just checking out with other users for their opinion.
Do any of you experience the same noise from the extruder?
Link to video

I'd like to eliminate that noise. It's not grinding against fillament.

I cannot view the video but just from seeing the first frame I can make educated guess that it's a bad extruder setup - large spur gear with few teeth and filament path is not straight. Clicking is most likely due to stepper missing steps as spur gear teeth dig in to the filament with different force depending on their position.

Please tell me why can't you see the video? I made it public for all audiences.

Any recommendations on setup? What about the gear size and teeth number?

I reduced the pressure between the spur gear and ball bearing and it helped smoothing the filament path and reducing noise. Still, it's transferring vibrations on the printer frame, thus making wavy patterns on the side of my print. ( "ringing" - correct me if I'm wrong).
I'm thinking about moving the extruder somewhere aside from the printer...

It's my PC that cannot play movies atm. Anyway, here are wheels that I had good experience with:





PS.: First one worked the best for me, however it clogs up more (it also works better with weaker steppers). Note that first needs flat pressure wheel, second with a grove. It's probably the best to get whole extruder assembly if you're just starting or you can print your own:

Problem solved. It appears I had some loose screws on my extruder.
Thanks Bob!
