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
used to happen to my K30 after change blurs.. but everything seems alright
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?

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.
Brilliant, that's great to know, was worried this next grinder was out of whack like my last one, hence why I asked hehe, thanks guys big help!!

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.

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.

Appreciate the help
