Yes, quite loudly. I've had mine a few months, but that noise that sounds like it's coming from the spring only started a few weeks ago. I get it with every crank.

That's weird. It's definitely the spring on the inner burr. Just go on and disassemble the inner burr, the alignment won't be affected. Keep setting the grind coarser until the burr disengage. There will be a small key/pin, a spring, and also the inner burr cone. Catch them in your palm. Seat them back properly should solve the click noise (never had one myself).

I did notice something like that when I first received mine. I found out it's actually the key for the outer ring burr. If you remove the 3 allen screws securing the ring burr you'll notice a small rounded rectangle key in a slot. This keeps the burr from spinning. Mine is just loose enough it slides in the slot and creates a small ping if shaken or moved.

i concur. it is the little rectangular key that holds the outer burr in the proper orientation. there can be some slight play in it laterally and it can move around causing the "clink."

Correct, sounds like a tiny bell.

I had been thinking it was the spring. That's the kind of sound it makes. This morning, I disassembled. In the past, I've taken it all apart, but hadn't ever removed the spring from its axle. That's the only thing I hadn't taken apart before. When I put it back together, I made sure everything was seated as it should be. It wasn't seated incorrectly to begin with. When I put it back together, it was quiet again - for about 2 turns of the crank. It's better than it was, but it's still happening. I'd think that if it were the key that prevents the outer burr from moving, that I could shake the grinder and hear it rattle. But that never happens and hasn't ever happened. It seems plausible enough, though. There's certainly play in its space. This isn't hard to live with, but it's kind of disconcerting.

I've just looked at my Helor. Looking at the mechanism, it's quite unlikely for the spring to make any noise. The spring, inner shaft, key, and inner burr cone should all be moving as a single piece. If it's really the spring, maybe you can flip the spring upside down to see if it helps? Also, when you are reinstalling the inner burr (before putting on the grind-setting lock cap), it'd be a good practice to use your thumbs to push on the inner burr up and down a few times. That would compress the spring and make sure the spring is free moving/mounted properly.

Could you make a video to capture the sound? Does the clicking sound happen when cranking an empty grinder?

If it's the outer burr key that rattles, yes it should quite obvious by shaking the grinder.

I think I am the one responsible for the spring idea... It was merely a guess based on how it sounded; it sounded quite like a spring getting stuck on something and then popping out.

Adding to that, it seemed to happen once per revolution. However, that can be explained by slight changes in tilt, causing the key to move once per revolution.

related to espresso grind settings on the helor (with contemporary burrs)... does anyone have any tip as to what might be going on with my shot here? it is set to 14.5 dots past the completely locked zero point and i'm using 16g of 1.5 week post-roast coffee. finer? coarser? i think the general consensus is that 12-17 dots post-zero is good for espresso no? fwiw, a post-shot basket diagnosis revealed only one fairly small channel.

I would go one dot finer and one dot coarser from where you're at. Also WDT will be helpful.
