How to Align an EK43 Grinder

gg

Awesome. Thanks.

Just ordered our first EK43, I assume this is something you should do as soon as you get started?

Question, how does scratching the shearplare make it snug not more looser? shearplare

thank you!

Is it necessary to also do the moving burr? If you've correctly aligned the stationary burr, wouldn't that mean the burrs are parallel with eachother so starting to shim the moving burr would change the alignement you've worked hard to create in th first place?
Thanks for the tutorial in any case and also the vidoe showing how different alignments sound!

I did this on my ceado. It works pretty good. Needed to shim both burrs and it seems a little better, but not hugely on mine, but can't really know until you do it. No reason not to do it really.

Great guide, I aligned my EK43 earlier today. It's amazing how much 6 bits of foil can make, grinds look more a more consistent size and even the sound of grinding as changed completely. Next up is to dial in a Kenyan filter coffee which has a bitter/roasty note masking some nice fruity flavours on 60g/l.

Is it necassary to align the burrs if you're just using the EK for filter? (Assuming they aren't way off) Or do you only need this level of precision for espresso?

Should we treat the others grinders with same respect? My Anfims also need to be aligned in order to perform better. :) nice vid Matt, thanks a lot

great video, my lazy alignment would be just to let it run for sometime with touching burs so it evens out on its own ;)...well i fear that would not really be a pros choice tough...

How important is it to have excellent alignment when you're only making pour over?

You cannot align the moving Burr.

Great vid. Lots of work.

Right, put the shims on the non-moving burr...thanks Matt.

Is this the same one you used in the 2013 WBC??

is there a limit of how many layers of shim we can add ?

I did this on compak k6. first on the non-moving burr and then moved on to the moving burr. it finally rubs the marker off evenly.
it took me 14 layers and 9 layers of aluminium foil on non-moving and moving burr respectively to align. this grinder was a second hand and its alignment was really bad at first.

this should have been sorted out at the factory and not messing around with some pen and foil....

Perfect explanations . Just did that on a MDF Gaggia (where the threaded mobile part does not help parallelism) visible results, audible results , thanks ;) IS it in a maintenance center it was filmed ?

Damn I don't understand anything of this video. Why do I have to do some shit to a world class grinder. Please help me, I really I am really new to coffee.

It is a shame that even such an expensive grinder has no better solution for calibration. They could have foreseen some counter screws so that no shims have to be used, or at least provided some shims of different thickness with the machine, that would fit in some small pockets so calibration is not so DIY...

Pro tip: Shims should be placed at the screw locations, not in between. If you need to raise an area that is in between two screws, you want to shim both adjacent screws. Believe it or not, by shimming between screws, you're flexing the burr when you tighten it. Source: I do a lot of precision machinist work.

Hi, thank you, have you ever tried to align commercial espresso grinder like fiorenzato F83?

Thank you for this helpful video ! Might get a used EK43.

So we adjust the stationary burr against moving burr that's not yet adjusted/balanced?

or you can buy a Weber!

What a G

Imagine getting a 3-4K grinder and it didn’t come with perfect alignment. Ek43 is a good grinder produced by lazy manufacturer, they didn’t even have faith in this model and almost discontinue it in 2013, luckily it shines in the world Batista competition before they done it

Brilliant video, thanks so much for explaining this in a simple to follow manner 👍

I have a question I clean the machine after assembling the grinder but it never came up

Did anyone try the Bentwood V63? They claim they don't have this issue.

I've been leant an Atom 65 (currently using a J-max) by a friend and thought it would be great to check the alignment of the burrs to make sure all is running well before I begin. His was used in his coffee shop but burrs seem in good shape. Performing the marker test everything seems even all around, but the flats aren't completely cleaned of marker. The inner point remains and only the outer edge is rubbed away. On both top and bottom burrs. So I'm not really sure if that's normal or where to go from here haha. Any advice from anyone?

Does it help with slower extraction of espresso as my ek 43 already make chirping sounds but the grind results still very coarse? Or shall i change my burrs to turkish one?

I frankly don't understand the need to align the second burr. What we look for is parallelism between the two burrs. We find the "perfect" position in which one burr is parallel to the other. If parallelism is the problem, then there is only one adjustment to be made, because if burr A is parallel to burr B, then burr B is parallel to burr A. If, on the other hand, one of the two burrs is irregularly consumed, i.e. the teeth do not lie on the same horizontal plane, then that is another problem, and that should probably be solved by replacing the burr set.

dont do that anymore

Legend! Thank you for this

As a laser engineer, used to do some serious alignment on precision gear, I'm not a huge fan of this kind of grinders because of the alignment.

No need to place a little amount of glue on the foil to keep it firm?

If necessary, this is the ONLY way burrs should be aligned. Do NOT use the indicator method!

I’m actually confused about this, if both burrs are misaligned how can you test the alignment of one against the other?
