I noticed my grind size setting moves when i grind my coffee beans. I was grinding a few cups of 12grams/cup at grind setting no. 40. After the 5th cup, my grind setting moved to 41. Anyone else out there with this issue?

How long have you had it. How often do you clean it. Is the adjustment indicator ring loose by chance?

Hi, I purchased it about 2 months ago, I use it almost everyday and I clean it every week or sometimes bi-weekly. I haven't noticed this issue before this. The black indicator ring pops out a little at one side, maybe about 1 - 2mm. It was like that when i newly purchased it.

Contact Niche. I know that they upgraded the springs to fix this.

True, but they replaced mine and I still have the same problem.
Don't believe the hype, the Niche is OK, but it has problems for sure. This being one of them. I have had it from the beginning and it hasn't improved. In fact it is getting worse these days.
Can't wait for my Monolith Flat to arrive!

There is very little data to suggest this is a prevalent problem. The Monolith flat has its own issues with ground coffee compacting in the adjustment mechanism and not having repeatable grinds. Only some of the established italian grinder manufacturers have 'solved' repeatability issues, often using overly complex methods that introduce other problems. It is simply not easy to do wide swings of adjustment when your precision alignment system is encountering an ongoing dry fine particle contamination.

There was a grinder at host that flushed the grind chamber with gas to reduce retention in increase accurate repeatability, think of the complexity in that system, wild! :mrgreen:

Mine moves a bit. When I notice I move it back. A bit annoying, but it's not like it ruins the coffee.

I have not noticed this happening with mine.

I did post a potential fix. Use clear silicone adhesive bumpers on the inner lid in the back to put slight pressure on the adjustment ring. Shouldn't take much pressure.

Below is a link that might help: Niche Zero grinder

My Niche has been my daily grinder since Oct 2018 and it never creeped or slipped.

Same here. 1 year and no slippage.
