When I first got my Rocky, did the find "0" point and adjust back thing, put some beans in and...
nothing came out. The residue from so called factory testing was a bit sticky :(
It is also not unusual for the beans to stick and nothing comes out, depending a bit on how oily your beans are, lighter roasted beans probably less troublesome ;)
So the fix is to give Rocky a belt around the midriff to dislodge the sticking beans, yeah really :) (Not on the hopper, but anywhere on the metal is OK)
A clean down of the hopper and inlet into the grind chamber wouldnt hurt occasionally either.
So far I havent mastered being able to firmly tap the side of Rocky and hold the switch in at the same time ;)
Watery pucks I thought usually meant underdosing.
Suggest try more coffee rather than firmer tamp, and yes if you need 20g to just touch the shower screen, thats probably what you should be doing. Might even need to go back one setting on Rocky.
Also clean out any grinds left in the chute overnight, before you start again the next day, easiest way is to get a "Click-Clack" container from the supermarket, many of them have a lid that just fits into the bean hopper, and a quick firm push down will dislodge grinds sitting in the horizontal section of the chute. :)
This of course also assumes that you are using fresh beans, and allowing Botticelli at least 30 mins to warm up thoroughly, 45-60 mins is even better.
As far as grind setting goes, the actual grind will vary from one Rocky to another, so grind setting isnt much help for diagnosis, as long as you know what works for you.
However I have found a couple of times that the weather can have significant affect, with rainy conditions requiring a finer grind, and if the weather is changing while youre trying to dial in, it can get a bit confusing. Also remember there is something like 5g of grinds still in the chute when you first stop grinding, unless you clean out the chute, so new setting wont take affect till that is all gone.
For consistent grinding it also helps to make sure there is at least 4cm of beans in the hopper, if you try to put in only the amount of beans you want at any given time, they tend to get thrown around inside the chamber and the grind can get a bit varied. If you dont use a lot of beans each day then just make it the 4cm, and add daily, as long as there is a minimum amount in the hopper, another reason why you want to start with fresh beans.
Try some different beans, make sure they are fresh.
Im roasting nearly every week, and trying different blends,
yet mostly the grind setting doesnt change much now, (we have a heat pump going most of the time this time of year, which moderates the affect of weather changes outside).
Hope this is of some help.
Great post Bullit,
Definitely deserves the [smiley=tekst-toppie.gif] award :). And what you have said about using freshly roasted beans can not be over-emphasised, otherwise it just becomes a tail chasing exercise that ends in utter frustration. Good one [smiley=thumbsup.gif]
