The Niche looks larger than I expected: your Major is BIG, but the Niche doesn’t disappear against it - at least unless one puts a 1.6 kg hopper on the big ’un.
One thing I’m experimenting with is putting a book under the rear feet to tilt the grinder forward (on a Ceado E37S, so similar to the Major). It seems to work well if I have a small amount of beans in the chamber - they all get ground quickly (with a bit of chaff at the very end) and I get even better dose consistency. I may build a permanent wooden support.
