I agree

Currently I'm contemplating whether it's worth changing the grind setting during grinding to achieve something similar to 'grind profiling'. I can do pretty much what I want with the burr gap whilst the motor is operational, either automatically or manually via buttons. The idea is to create a denser puck and see if that helps in any way with brewing. A less advanced method of doing this is to simply grind two batches of coffee at two different grind settings and mix them up to create the final dose. My guess is something similar happens already on grinders which are single dosed and seem to produce a coarser grind towards the end when there's less beans in the bean chamber.

I've tried something like that to cope with the stepped adjustment on my super caimano, but the results have all been awful. Have you had better results?

I haven't done much testing to be honest, currently the idea is to tighten the grind a bit more towards the end of the grind and try to battle any coarser bits coming out of the grinder due to lack of weight on top of the beans (there's constant weight on top of the beans but even that idea has it's limits). I'm assuming here that is what happens of course, what I should do really is compare the grinds on the output at the beginning and end of the grinding cycle.

If you're ready to work on grind profiling it seems like you might be gilding the lily. Is it time to birth the grinder into the wild to see what problems still exist with the design but that only show up in real use?

So here is a question for you all; how many grams/pounds of beans above the burrs do you think will provide a consistent grind density?

Not sure to be honest, so I took a guess and went with a weight very close to 600g. This is of course only effective till around 70-80% is gone, as later on the weight simply stops and rests on the burrset, whilst the last few grams are being ground. This is the moment where I think the grinder can benefit from tightening the grind setting.

As for releasing the grinder - this is a big task as the assembly itself takes a long time which I simply haven't got. This is of course only the tip of the iceberg with pre-release issues...

How fast can the grind settings be changed? Can the grinder "pulse" its settings many times while grinding a double dose? If so it might mix in the chute; or create many layers of alternating density. Might be better than a linear profile.

I would imagine that this might vary quite a bit depending on the grind setting?
