BigTTony think of it as rubbing with fine emery paper (400 or 600 grit) to remove the surface shine only, creating a matt surface. It’s a really light sanding.
Wipe down with a degreaser first, Alcohol, Glass Cleaner etc.

OK, quick update. I’ve cleaned the niche and when doing so I noticed that the 10mm bolt was loose. I’ve given it a good clean (and it needed it) and now it’s all back together. The top part seems more sturdy than it was, but time will tell if it has rectified the issue.
One question though - trying to dial it back in is a but of a nightmare. I’ve done 4 sink shots because the grind was way too loose on the 19th dot. I had to take it all the way down to the 10th dot just to get it to pull a shot within a semi reasonable time and even then, it was 10 secs too fast. I’ve now set it to the 8th dot for my next go this afternoon as I’m running out of beans until the postie delivers my next batch.
Is it normal to have to go down this many dots? I thought it would be out by a little bit and I’d have to tweak it back towards the 18-19 mark, but it feels way off. Any advice? I’ve followed the calibration videos on YT so I don’t think it’s that ie screw the chrome ring all the way to the right, align the chrome dot with the arrow to calibrate, then move the dial back to the left until you reach your preferred dot.

BigTTony Morning! My typical espresso range is 11 down to 7. When I read your initial thoughts, you were at 19 which in my humble was way to coarse. Glad you have sorted it

I hope problem was because bolt being loose and now sorted.
8 is totally normal, your grinder now properly calibrated I believe. My typical range is 7-12 decaf to caf.
I recommend marking silver funnel also with a dot where they align with calibration dot on black ring. So even if you move black ring by mistake you can come back to where it was.
Yep. Mine is usually at 9 for my espresso and 50 for drip.
Fingers crossed it’s sorted. Thanks for all the help and suggestions.
Mine started doing the same and a good clean sorted it for me. Hopefully yours will be the same.
My Niche did the same. It is annoying as you have to keep watching to make sure it hasn’t drifted off.
I just followed DaveC vid to clean it thoroughly and put it back together without any sanding or greasing and it cured it.
My espresso range for medium to medium-dark roast is 8 - 11
Lot’s of Niche related threads, so let’s post my query here:
Have had my NZ for approx 6 months, and after the initial period of seasoning, the amount of ground coffee coming out was +/- 0.1-0.2 grams of the beans weight. As of last week I get quite an inconsistent output, often in the region of 0.5-0.6 grams.
I usually make 2 espressos+ 2 pourovers per day, so I switch between finer and coarser settings. Last cleaning performed 2 months ago.
Any thoughts? Should I just give it a deep clean?
Thanks

Do you grind frozen beans?
Inspector Nope
Is it a fresh bean?
I have some beans that are a $hitshow and stick in the niche cup 😱

ChristosC Might be worth giving it a clean, remember you don’t need to recalibrate, so it won’t affect your grind settings
Even get a micro fibre cloth up the exit tube.
Winter can also do funny things. I’m noticing a bit more static.
90% it’ll be the bean.
What are they
I got some from A1 roasters..
