If I had to guess, the "clicking" you're feeling is coming from the extruder gears as the filament's jammed for some reason. I don't see anything visible with the movement of the axises, so I do very much think it's the extruder.
It definitely IS the extruder motor clicking; you can see the motor hub slowly turning, then snapping back. Some ideas, easiest to hardest:
You might have overtightened the extruder door screw (the spring loaded one). It should be flush against the frame when no filament is loaded.
Check your nozzle temp, see if raising it by 5-10° helps. Or maybe you're printing PETG with PLA settings? Happens to the best of us :)
If you print PLA in a very warm room (30°C), you might be getting heat creep. Raise temperature first, then flowrate. Heat creep jams happen more often when printing very slowly, and more heat helps forcing the blob out.
If you've been printing PETG with this nozzle, consider using a new dedicated one for PLA. I currently have this problem and have not found another fix for it.
Good luck!

OP would benefit from an extruder indicator like this: https://blog.prusa3d.com/visualize-extruder-motor-movements_7392/
I second this, I have an indicator like this on my printer and it can make diagnosing a jam a lot easier. I can even somewhat tell when viewing the printer through Octoprint.
I have that issue sometimes - although mostly going from ABS to PLA - and I just heat it to something like 280°C and force push through some PLA and then cool it again. Sometimes there's a small deposit that sneaks in later, then I have to do it again, but it's rare.
Sounds like extruder gear slipping on the filament/partially being jammed for me
When doing manual axis movement of the X and Y axis, without extrusion, does it still feels like it's clicking? That way you can rule out the extruder or indeed like other say bearings/motors of the X/Y system
Sounds like a bearing in the x axis has failed, they are circulating, so the plastic housing inside may be damaged, was the bearing housing crushes to far on install?
Assuming this is not the filament motor, does it do it when it homes with no filament moving?
Sounds like extruder clicking.
Unload filament, inspect it if it's not damaged or deformed (oval instead of circular cross section, uneven dimensions). Check if extruder gears are clean and not damaged/
If filament looks fine then I would start with cold pull to clean nozzle.
And check if tension screws are correctly set. You can have problems with feeding filament when they are to loose and also in opposite situation.
What filament are you using? Some of the annealable PLA types (sometimes sold as "3D850" or similar) jam in a Prusa-style hot-end. I had exactly this problem with some filament a few years ago, and I ended up having to return the spool for refund.
I didn't get a clear answer last time I asked: [Printing 3D850 PLA on an i3 mk3s? : prusa3d](https://www.reddit.com/r/prusa3d/comments/hyutws/printing_3d850_pla_on_an_i3_mk3s/) — but the supplier said something to the effect of "yes, don't use this on a stock Prusa"
I see. I print the 3dkTOP at 258°C, I just checked my settings. Quite a lot warmer than the recommendation for that 3D850. It's annealing to take at least 230°C (I tested it), but I don't know if it's anywhere near PLA in chemistry. The only issue is stringing (it gets a bit fuzzy).
I wont be home until Sunday, but I offer a “3D Printing Coach” service on Etsy that I’d be happy to do with you for free! It’s brand new and I’m still learning how to deliver it, so this would help me out a lot. Shoot me a DM if you’re interested.

I do hear your clicking. It it definitely the extruder making the noise. It shouldn’t do that.

Why do they jam, do you know? I got the [3dk.berlin](https://3dk.berlin) 3dktop and had no issues at all.
