Chris--I did the rice test on my grinder, both with my routine chute sweeps and without them. In short, you're right about how bad it is with a full chute. My test results suggest that it may be even worse than the Robur E, as the lack of the anti-static screen means that the chute never really fills up entirely, preferring to fill up mostly and then throw the coffee out primarily through the upper-right corner. The 'stopped up' sections of the chute seem to slowly mix with the high-velocity section, but again the operative word is slowly. With my ritual chute-sweeping, it's pretty decent, as the empty chute seems to free it to "throw" the full contents of each vane in the grinding chamber as it passes by the chute. The problem, though, is that the output is a lot more statically charged upon exit with the empty chute, so the entire doser gets peppered, and even the grinds in the bottom part cling to the sides of the vanes and the sides of the doser that aren't swept. This is no surprise (my Robur has been like this since I bought it, of course), but it becomes a serious source of mess when you're thinking of converting to doserless. From what I can see right now, the basic Robur design presents the would-be doserless converter (including Mazzer themselves with the E model) with a choice between extremely messy static from a fully purged chute, or a rather wasteful purgation of spent grinds, whatever the exact cause of that may be.

Anyway, I'll post more details and some photos from my test when I get a chance.

You sure?



I'd be interested to hear you chime in about what level of coffee is held up behind the screen, and how you deal with that (just purging the waste in the morning, etc.).
