@tompoland Sorry I mean to pester you but you have knowledge about this grinder.
I have removed the grubb screw but very hesitant/apprehensive as to how “tight” to push it.
In this video, I have the dial set from the 1st dot (the smallest dot being zero, then the half then 1). At this setting, using a medium-ish roast blend, I got a 1 to 2.3 ratio in 19 seconds, which obviously means I can go finer. I got almost taste the notes, but there was a little sourness present.
But when I adjust the dial finer, getting to about half the audible note changes (almost as if the burrs might be touching?). I’ve then switched it off, and you can see how far tighter I can actually go.
Any guidance, please? The change in audible note, are the burrs doing anything crazy?
