Compak K3 Touch Newbie
Just hoping for a little advice.I've been a member here for some time now and have picked up lots of hot tips regarding all facets of the coffee game,this truly is a fantastic site for collecting knowledge to hone ones skills as a home roaster/ barista etc.
Anyhow this is my first post and any help offered would be greatly appreciated.
I've been using my Miss Silvia paired with a Sunbeam EM0480 for over 7yrs now and up until recently have been quite content with the shots I've achieved but there has always been this desire to upgrade the grinder for something better.
Having read a lot about the Compak K3 and after much deliberation decided to purchase one on Gumtree the other day.Its a K3 Touch Advanced GOD stamped 2012 and has never been taken out of the box (unwanted wedding present) I was told it has just been stored in a garage for a year and a half.
I picked it up for $200.00.. Not really sure what the the going price would be but
it didn't seem like much of an out lay considering I was about to pay $700.00ish for
Mazer mini manual.
Anyway my probs are...
1. The collar has little bit of horizontal play in it
and I'm wondering if there is a fix for that??? Haven't been able find any talk about it on any of the posts that I have trawled through.
2. How many kilos do you think I will have to put through before the burrs settle in???
I've been through almost a kilo already and I haven't been able to pour a good shot yet.
I know a lot of it boils down to driver error but I feel my techniques are down pat.
Changing the dial by only 2 increments seems to go from a slightly fast pours to too slow.
Once again any advice would be greatly appreciated

If it's anything like my K3 Touch then it also has horizontal play it it, however this doesn't seem to change the grind. You need you turn quite firmly to move the burrs up or down.
I can't answer the settle in period and might suggest you are simply turning too far? I don't use the notches as a guide as they mean nothing to me. If it pours too fast I use my judgement I've acquired from use and the look of the clumps of the grind.
If it's just ever so slightly clumpy, I know I'm close.
You get used to how far to turn the collar, but for most beans it doesn't require more than a cm or so of turning. Except for the Biftu Geisha which I swear i have to grind Turkish to slow it down!
And lastly, using quality beans and staying away from supermarket is a must.

Thanks for the response guys.
I might just have to keep an eye on just how far I move the collar.
Still not all that familiar with a stepless yet.
As far as beans are concerned...not having fresh beans isn't the problem
I've been a home roaster for years thanks to my correto
so I wouldn't even consider supermarket beans
Barry...the play in the collar really isn't that big a deal
I guess I'm just being a little anal about my new toy
Having said that it would be great to have a fix
Wouldn't lose too much sleep over it mate. If you are seeking a reliable standard, just take your readings from the numbers on the collar after lightly pushing the collar clockwise (without moving the burrs). You got a great buy at $200.

With a little consistency I should eventually get back to a good shot.
Re the price I paid....
wasn't to sure what one stamped 2012 was going
for but considering it is 'as new' still in box I guess I didn't do to bad
I have a similar grinder, how often should you replace the burrs?
K3 Touch owner as well and I concur at $200 you got a very good buy (it'd still be a pretty decent buy at double that price!!!).
Mine's stamped 2009 but as it was sold through a smaller regional outlet was only first used in 2012 as well. Recently got a brand new set of burrs and circuit board (due to no fault of the machine, of all things a Gecko decided to make the board his final resting place). Is almost as new and never misses a beat.
I to have that tiny bit of play but it's really not a factor at all - once you're close to having it dialed in there's zero play on mine. I use with a Silvia V3. Stick to your known dose weights and light tamp adjust the grind until you get what you're wanting. I find small adjustments are needed to maintain these 'syrupy' extractions as the beans age or different roasts/combos of beans but it will only be a very small (3-5mm either way) from your original dialled in point.
At that point I get quite a bit of clumping as well - I generally make coffee for 2 people at once, grind all in one lot (I always use my finger up the outlet to remove as much of the grinds as possible to avoid wastage and also stale ones on next shot). Add to basket and weigh, use a small blunted disection needle to 'WDM' it.
Every week when the kitchen is vacuumed I stick the nozzle down the grinder and suck out what i can - but I'll be loathe to undo unless needed.
Is a very good grinder and at that price a VERY good buy. :-)
What type of similar grinder are you referring to Studel?
From what I've read the 58mm flat burrs on something like a K3 should last a very long time when used in a non commercial situation and even when they do need replacing the cost from what I gather doesn't seem to be that bad.
Nikko after a lot of trial and error and close to a kilo of beans later
I'm managing to dial in the grind with a lot more consistency
As per Depecid comment... keeping an eye on when it just starts to the clump
does give me a good indication of how close I am to being dialed in correctly.
I've come to the conclusion that the play in the collar really isn't an issue at all.
Also I don't bother with the timer as I just measure my dose and grind on demand.
I must say I had my heart set on a Mazzer mini type B
prior to my purchase
as the Mazzers just seem to be of such a solid build quality
but most people I spoke to kept telling me the type B
(which was the model that I was interested in)was
not the best choice in that price bracket.
Still not a 100% sure why???
Now having a K3 I really can't complain.
It does appear to be a great little grinder and
hopefully it will be with me for many years
just like Miss Silvia
