Hey! I've been making coffee now for over a year, but am just recently really getting into the works of espresso. I still feel like a newb sometimes, and this is one of those areas.

I have a Nuova Simonelli  MDX-A Grinder. It uses a "Vernier Scale" for the grind. I have no idea how to use it properly. I just mess with the dial and pull some shots until it's right. I have tried looking up how one works and it all just goes over my head. I don't understand how the stationary numbers on the grinder correspond with the numbers on the nob.

I've been looking through Coffeegeek and can't find anything about it at all. I didn't even know that my scale on my grinder was a vernier scale until I saw my Grinder mentioned here.

I would really love some help! Thanx!

Serene

Check these 2 websites out.  Pretty much, you read it from the start of the smaller scale to get the big number (1, 2, etc.) and then count the shorter line of  notches until one of them lines up with the other scale.  If you have 9 shorter notches, then each click is (.1, .2, etc.)  If you have 4, then they are (.2, .4, .6, .8.).

I'm just guessing this is the scheme of your grinder.  But the principle is the same.  I had not idea any commercial grinder came with a vernier.  Take a photo for us please!!!  I'm excited to get the hg-one to put a vernier on it.

Thank-You that helps. I feel like it should be easier then I think it is. I feel like I'm making it way harder. But I'll keep practicing and researching.

It's a step-less grinder, there is no clicking when your tuning -up the grind measurements. It'a a micro? adjustment, I think that's what it's called.  It's really nice and I can get a really good grind out of it. I 'm the new head barista at the place I work; it's a coffee bar inside of another business. So, we're pretty small scale there are only 3 baristas including myself.

I'll be sure to try to get a picture for you. However, there not uncommon. Nuova Simonelli still makes them.

Thanks for your help!

My MDM has the following knob.  I think it's very similar to the MDX adjustment.
