    When the grinder next runs low on beans let it run completely out. Then very very slowly dial it finer with the motor running until you hear it just begin to "sing" - some people say chirp. Note the setting - that's the grinder's zero point. There are videos showing how to do this on youtube if you want to see someone do it so you are clear on what to do. Then you will have no doubt what the point at which your burrs will grind is and put your mind at rest.

    Thanks for that. I've only zeroed the grinder twice. So with the noise of the motor predominant, there was some uncertainty whether what I was hearing in that last couple of secs was the burrs just nicking or not (if they were not properly aligned.) As I've not heard burrs barely grinding against each other from misalignment. So to you who have there may be the comment akin to well, if they did hit each other at 1400 rpm you'd hear it real quick or if the misalignment is at some small but barely significant point it may not sound much at all. I don't know unfortunately as I don't have the experience.

    And certainly, Andy, Dave Corbey's Morning thoughts on finding a rock in your beans was something me as a newbie hadn't really considered. (I should have with the wife finding glass in her Muesli Bar a couple of years back.)

    I guess my takeaway from this is that if the burrs were grinding against each other I'd know about it.

    Thank you, gents, for your replies.

    The burrs will last (nearly) forever when they are grinding air.

    Grinding stuff wears burrs, grinding harder stuff wears them faster, grinding stuff that doesn't grind typically kills them.

    Unless you hear the burrs hitting each other then no, you're not damaging the burrs.

  • Am I damaging my burrs on a Macap M2M with a single dose method of grinding.

    I felt I was leaving too much coffee in the hopper with the Macap M2M.

    I decided to treat it as a single dose machine with a weighed amount of beans.

    The good thing was in <=> out was very close (even if that meant some old for new, and very little popcorning.)

    But in the process say with 29g for a pour over around the high 26g/low 27g mark the grind has ostensibly stopped and I can't really hear the coffee beans being ground during the remaining couple of secs the last 1-2g comes out.

    There's not much being ground at this point - am I doing damage to the burrs for that last portion when there is almost none/no beans between the burrs?


    Thanks
