There is no documentation for this excellent grinder but I did find this site with some explanations.
Some advice ... As there is no markings on the dial I found that one revolution altered the time for a 30ml extraction (using the same tamp technique) about 4 seconds. This has helped me dial in a particular bean. Also if moving from espresso to plunger then count the revolutions so you can get back to your original setting easily.
By the way what coffee machine are you using?
Barri, this may be a "how long is a piece of string?" kind of question, but roughly how many turns do you normally back off the adjuster to go from espresso to plunger? I know that it wont be an exact science but more from curiousities sack. (and i know that is what killed the cat but I still need to ask) :D
Im glad I basically only have espressos otherwise Id get RSI. ;)
Well you could always have a La Cimbali Jnr....
50 turns makes 1 mm difference to the grind size..... No wonder it is often claimed they are the most finely adjustable grinder for espresso..... But definite RSI risk changing to plunger and back.....

Doesnt work with a La Cimbali Jnr (round knob) :(Originally Posted by Mal link=1172720819/0#6 date=1172744635
Mind you I could always make something up if I had to..... but thats what the KG100 is for - plunger only!!
Thanks for the replies guys,
Im finding with my Iberital im getting a good extraction of around 30 seconds for 30mls but after i pull the group head off the machine the coffee grounds are still very soggy and watery. What does this mean? Does it mean that my grind is too fine or that i havent tamped enough or dont have enough coffee in the group head. I beleive that ive filed it with enough coffee
Wet pucks are generally a sign of under dosing - you need to put enough coffee into the basket so that - after tamping - when you load the PF the shower screen just touches the surface of the puck - often the centre fixing bolt will leave a small mark in the puck.
It should be a tight fit into the group assembly - not so much coffee that it wont fit without force.... but if you remove it and check pre extraction you should just see that the shower screen has touched the puck ......
ah thanks for that will have to try that tomorrow morning, i have noticed the last two times that the assembly of the group head hasnt been that tight
cool i increased the dose and it gave me a 60 second extraction, whilst the puck was firm when i knocked it out around the top it was still a bit wet. What variable should I be changing next? More finer grind?

OK you are almost there..... the pour is way too long so make your grind a bit coarser until you get the 30 second pour - and you should have a dry puck as well. :)
About 6 or so coarser revolutions of the knob should do it. Then fine tune after that.
Ive got the Iberital Challenge with the doser.
I find that if you have two of the bays in the doser filled to the brim, thats the perfect amount to fill your portafilter. Two clicks and youre done.
To minimise wastage (and the doser definitely increases the wastage), I use a brush end or my finger to push the coffee into the bays as it grinds.
This is a great grinder, but Ive given up trying to change the grind for anything but espresso.
To add to the perennial doser vs non-doser debate, Id add this; a doser adds nothing when youre making a simple double shot. When youve got friends around and youre making a few coffees, nothing beats them.
