    Compak K3 Touch Adv funny noise...

    Hey guys, not really sure if this is an issue or not, but when grinding with my Compak K3 (even when there are no beans in there) and I push gently on the collar it lets out a noise similar to when the burrs touch at zero point... is this an issue at all? I'm not sure if something is misaligned, shots seem to be going mostly okay, or whether it's just the burrs touching down on some bean fragments that are caught in between (which I can see there are shards of beans in there)?

    I posted a vid of this noise... I think someone else has posted a vid up of the same issue...

    Thanks for any advice guys

    Ah that's good to know, thanks for that. It's just strange and I'm wondering why it does that... and hopefully that it stabilises itself while grinding beans?

    The sounds seem to imply that the burrs can tilt but I don't know if that's what the noise represents...

    Hi Simon, it seems somewhat similar to how my K3 behaves when I run it empty. If I grind what seems to be the last bit of beans out of the throat and then stop, it briefly makes a similar sound as it winds down. I suppose under those conditions the burrs can tilt a bit. If there is some load of beans on it, then while it is running, I can even tighten the grind a bit finer than where I calibrated the zero point last time I cleaned the burrs without it getting more noisy or jamming. I wouldn’t worry too much.

    Hi Simon,

    The upper burr carrier in the K3 unfortunately isn't designed to fit perfectly inside the threaded collar. There will always be a little bit of play left and right which will result in the burrs touching from time to time if you apply uneven pressure on top.

    If you take out the top burr carrier you will notice the three extrusions on the outside that meet up with the three channels on the thread inside the grinder. This bugged me at one point when I owned your grinder, so I searched around and found that some people create shims that help the three extrusions fit perfectly inside the threaded collar.

    Some talk of it here: https://www.home-barista.com/advice/...ch-t10551.html

    Ah thanks so much chiming in there Sam appreciate it mate!! Ahh I see... that's such a strange design flaw hey.. seems to be an important thing, but if it only does it if i apply pressure on while grinding, and not while normal grinding itself then I'd be happy with that. As long as it grinds consistently...I just wont touch the collar while grinding hehe.

    Cheers for link mate I might look into that, I certainly don't wanna damage the burrs!

    Appreciate the help
