In a properly calibrated grinder the burrs will not be touching. The burrs only touch briefly during the calibration process, which isn't enough time to cause any damage.
wait that means, everytime we disassemble the grinder, the numbers may change?! that means previously the burr touch each other at let's say number 3 next time you open up your grinder to clean, your "0" grind size might points to other number that 3?!
John Reynolds Hi John, excellent question. Burrs are generally replaced with new sets and not sharpened. A few ways to determine when to replace: 1. Age/amount of coffee ground: Some manufacturers will rate burrs for grinding a specific amount. ie. replace burrs after 2 years if grinding 10lbs./wk. 2. Ceramic burrs stay sharp longer than steel but are more brittle so more easily chipped. You can look and feel the burrs to appraise their sharpness. It's subjective so helps if you know how they felt when new. 3. Quality of espresso: If/when shot quality declines might be time to replace the burrs.
Typically adjusting down until hearing the burrs just touch is the way to find a zero point on this type of grinder. When you here them touch back off a bit. This very short touch should not hurt the burrs.
I just bought a Compak K3 Advanced touch. Sometimes when I turned it on, it would not grind, only making sound like the motor is running. What happen ? Is it because it needs certain time from first time 'on' until it can run properly ? or is it because the grind setting is too fine ? the manual says 'working cycle' : 2 minutes function, 10 minutes stop. Does it mean that after operation for 2 minutes, the grinder needs to rest for 10 minutes before doing the next grind ? What should I do if I already used the finest grind setting, but still cannot brew the right espresso (I got 40 ml in 25 second)?
Hi Ko, 40ml in 25 seconds is reasonable. a fairly standard good extraction is 60ml double shot in ~25 seconds. There are many other variables at play of course but 40ml in 25 sec sounds a little slow. The working cycle does mean what you think: 2 minutes on, 10 min. rest. If you turn it on and motor is running but not grinding something is stopping the beans from getting to the burrs. Even at its finest setting if the motor is running it should be grinding.
Thank you for your advice. Sorry, I meant 40 ml single shot in 25 second (=80 ml double in 25 seconds). I have set almost the finest grind. I wonder if the manufacturer setting is already the finest, or is it still possible to find the zero setting as your video show ? Thanks.
Ko Amin Samudera i own compak k3 i know what you mean because it happen to me once. You need a lot of trash beans when you just bought your compak k3. The grinder is not able to catch the bean properly at first so what you need to do is simply just turn on the grinder running at coarse setting while it is grinding the trash beans slowly turn the setting to fine espresso setting that you desire. For me i stop at 25 marker. Then i stop grinding and change the trash beans to my desired beans. Tara---~~ suddenly the grinder is able to catch the beans and grinding it very fine and consistenly from there. Thats how its done with this grinder when you first bought it. It need warming up by grinding beans from coarse to fine then it can grind any beans normally.
Hi yb, Yes, similar process. Just keep going finer with the grinder running until you hear the sound of the burrs just touching, then back off a hair till sound stops and that's the zero setting.
Hi B, Thanks for the question. The outer flat ring of the burr without teeth is slightly higher than the cutting teeth so they make contact well before there's any chance of the cutting edges making contact. Marc
nice video, well done. I was just disappointed by the comment about the italian trying to speak English. If I am learning a company name or a brand I try to learn the right way to pronounce it for example Mahlkonig. I didn't want to criticise, in the end of the day the video is really well done, I just found the comment a biy inopportune. thanks for the video anyway.
Exactly, i thought the same. It shows ignorance of the poster. Anyone raised in a different country to which ever language is being spoken will have their own sound. I actually think its beautiful to hear different pronunciation. I would love to hear them use anothers language
Hi S, Thanks for the question. On most grinders there is not. Numbers are there for reference. Some use a wax pencil or similar method to mark the zero point on the adjustment collar. Marc
@@Wholelattelovepage It was totally like you said. I took it apart and under the top burr was huge amount of caked on coffee. I cleaned it out and it worked perfectly. Unfortunately I removed the doser and the coffee just shoots out like a rocket, I might need to buy the cover thingy.
Very useful and informative video....except for the pronunciation is way off; 'Mahtz-err' for Mazzer and 'Ran-chilli-o' for Rancillio....they are after all 'lingua Italiana'.
+Drew Lawrence You should hear the Italian manufacturers who visit us trying to pronounce English words! Then there's the guys from Jura who pronounce it "Jura" and not "ura".
+Whole Latte Love No real excuse for the 'jUra' guys (assume you mean reps) not being able to pronounce their companies name. If you 'subbed' out the voice-over work in the above video then somebody really should have ensured that the pronunciation was correct...if it's all in-house production...well....no excuse really...... Didn't stop me subscribing tho'....I think the articles are informative and well produced :D
I don't get this video at all. I have had the Mazzer Mini for about 8 years now. For starters, no where in the manual does it tell you to do this calibration or allow the burrs to touch. This grinder already comes calibrated from the factory as indicated by the placement of the sticker on top of the collar. When taking it apart for cleaning, all you have to do is count and remember how many revolutions are needed to remove the adjustment collar. For me its 4 full revolutions. After cleaning, you simply align the center arrow of the sticker to the notch on the grinder and turn it the same amount of revolutions back on. As I said the factory has already calibrated it for you. So all you have to do is align that center arrow on the sticker with the notch of the grinder. Quite often, that has been the perfect spot to get the proper grind. At worse, I have only had to make minor adjustments no more than 1-2 notches either side of that. No reason to find the zero setting and certainly no reason to allow the burrs to touch.
Hi Frank, Thanks for the comment. Not sure what's not to get. Video shows how to clean and calibrate the grinder. Calibrating is not required but some users do want to know where the zero point is. Over time and depending on use level calibration will change with burr wear etc. While touching burrs sounds like a bad idea do understand the actual cutting surfaces of the burrs do not touch when doing this. The outer ring of each burr is slightly higher than the cutting surfaces.
The cleaning process is not perfect. You did not remove the screws from both burrs. The oily residues are beneath and both burrs need to be washed in warm soap water and perfectly dried.
Illustrative video, but cleaning process is far from perfect. You must also clean the burrs more thoroughly, which means removing the screws from burrs. Omitting this is fairly lazy approach.
In a properly calibrated grinder the burrs will not be touching. The burrs only touch briefly during the calibration process, which isn't enough time to cause any damage.
Great video - just what I need about every 4 months....
What a systematic and comprehensive guide... Keep up the good work..
Thanks for your comment!
You're welcome :)

Could you please make a video about calibration of ECM 64 titan and automatic?
Do you ever need to sharpen the burs or what are the factors to know when its time to replace the burs?

is there a better way to set zero point than having the 2 plate hit each other? isnt that wearing down the plate?

i have rocket fausto grinder,it is similar to calibrate my rocket fausto or not? thanks for your advice:)
Hi yb, Yes, similar process. Just keep going finer with the grinder running until you hear the sound of the burrs just touching, then back off a hair till sound stops and that's the zero setting.
Yeah,its work. Thank you.
Don't the burrs dull when they touch while calibrating? That sounded pretty scary.
Hi B, Thanks for the question. The outer flat ring of the burr without teeth is slightly higher than the cutting teeth so they make contact well before there's any chance of the cutting edges making contact.

Is there any way to set the zero point to the actual zero on the plate?
Hi S, Thanks for the question. On most grinders there is not. Numbers are there for reference. Some use a wax pencil or similar method to mark the zero point on the adjustment collar.
Marc
Ok, thank you!
If you dont have the adjustment screw is an issue ?
We suggest having the screw installed but the grinder will work without it with no effect on grinding performance.
Anyone knows how to control how many grams my grinder dispenses each flick?
Hi KK, Dosing grinders are typically adjusted by turning the center shaft in the hopper containing the ground coffee.

@@Wholelattelovepage Thank you, your reply was really helpful :)
Very useful, thank you.🖒

my mazzer mini stops even grinding at a very course setting
Hi Soren, That's a bummer! How old is the grinder? Does it stop if you take the top burr off?
@@Wholelattelovepage It was totally like you said. I took it apart and under the top burr was huge amount of caked on coffee. I cleaned it out and it worked perfectly. Unfortunately I removed the doser and the coffee just shoots out like a rocket, I might need to buy the cover thingy.
Hey Soren, Happy to hear you got the grinder going! A little confused... cn't you put the doser back on?
Why grind the burs together??? Seems like a bad idea!
Hi Cody, Not a problem. The outer smooth burr surfaces make contact first preventing the cutting teeth fro touching.
My grinder not working. I don’t know why?
Hi RS, What make/model grinder. Did you check the fuse?
