I've been hesitant to do that (I could get to 0.2, not 0, since I am 3.2) because I don't want to get past 0 if I need to adjust my grind finer (for no other reasons . AFAICT there is no way to move the numbers by less than 3 at a time because there are only 5 notches in the collar (and 15 / 5 = 3). It's slightly annoying... (So is the 5 micron adjustment which is ~ +/3 seconds for my espresso, though I can adjust dose in between steps.)

You could always adjust the speed to help dial in, though I don't do this.

I haven't seen any documentation that each incremental adjustment is 5 microns. Where is that found? Also, I've read on the thread each notch is +- 3 seconds. How is that determined?

If I remember correctly when Weber first introduced the Key, they said that it was stepped in 5 micron adjustments. This follows their design for the EG-1 and HG series.

Based on my experience using my Key and EG-1, I would agree that it's approximately 3 seconds between each step. I determine it when I dial in a new batch of beans.

Here's the link to the 5 micron adjustment, along with a nearly identical discussion following it. :P

This is how I received my Key. They say the grounds and smudging is normal. there is also a void in the paint circled in blue. What's the board's opinion? Is this acceptable in your eyes? what would you do if weber says it's acceptable? I contend that if this is offered as a high end quality product, then it should be perfect.

Thanks for your input.

How long on average does it take to grind 18g-ish dose for espresso at max RPM? I know this changes based on roast level/coarseness, but just looking for a general idea.

At 110, which is what I use, about 12 seconds. Max is 150.

Has anyone else who installed the bean feeder removed it and gone back to stock?

I've taken mine back out as I found that quite a few beans were getting stuck on the edges under the funnel and not making it through the holes and into the burrs.

I found it worked very well when the elastic was used to hold the funnel during installation, but no so well for every day use with the funnel in place. A shame the funnel isn't two magnetically attached semi-circles and easily removed. Maybe it's just my beans and/or technique, but I feel the impellers on the rotating part need to be a it bigger.
