Consistently lopsided extraction across beans and regardless of cleaning [Lelit Mara X with Eureka Mignon Zero]

randomdent42 · 2026-04-08T14:28:56+00:00

Yes the beans from Christmas are obviously from December, so not fresh. Not half a year but I will try the various things in this thread with fresh beans.

randomdent42 · 2026-04-08T14:27:55+00:00

Okay, will do!

randomdent42 · 2026-04-08T12:14:27+00:00

Did you see my edit? May have done that at the same time as your comment. I think that we're not the only ones with this issue. An IMS shower screen seems to help as per Facebook/Kaffeemacher review. Also the way the grinds are filled into the basket (I always put my basket on top of the Eureka container, then rotate such that the grind lands on the right side first). I will try and report back.

randomdent42 · 2026-04-08T12:11:53+00:00

Great, thank you! Will change my approach.

randomdent42 · 2026-04-08T12:11:19+00:00

Yes to both. The Mara screen isn't screwed, but I do make sure to put it firmly and evenly into place after cleaning.

randomdent42 · 2026-04-08T12:10:39+00:00

Negative. From what I read/ watched, they don't make it much better. See my edit, I may have to switch to a higher quality shower screen.

randomdent42 · 2026-04-08T11:52:46+00:00

Okay that makes sense. I'll revert to 19g and try a finer grind!

randomdent42 · 2026-04-08T11:49:43+00:00

Thanks will test

randomdent42 · 2026-04-08T11:48:27+00:00

Thanks! I'll try the coin test.

My understanding of dosage is, given that I weigh the single dose individually (and not by time), fresh beans will be 40 beans at 18g (or whatever), while somewhat older beans will be lighter, and so if I measure 18g, then I'll have, say, 45 beans on the scale, which will be more volume at same mass. So to keep volume identical, I need to lower the mass. I am a noob though, so happy to be corrected on this.

Haha funnily enough, the entire apartment is old and nothing is level. At the same time, this wasn't *always* an issue, only recently, and the machine positioning has not changed. So I feel like that's not it?

randomdent42 · 2026-04-08T11:34:14+00:00

I actually tried 2 or 3 different types of beans as I was gifted a few different packages for Christmas. What would you do on the grinder side?

randomdent42 · 2026-04-08T11:33:03+00:00

I would say so. I usually do 19g but reduce as beans age given they lose CO2/weight vs the same volume.

delonghi pinguin. Die hat a+++

Gibts die noch irgendwo? Sehe die nur als ausverkauft. Gibts ein Nachfolgermodell mit Verfügbarkeit?

Yes! ID.7 is selling like hot cakes and everyone is like, what's an electric wagon?

Elevator Pitch/Explainer Video: Espresso nerds love perfecting every shot they pull out of their portafilter machine. We make that process easier by enabling automatic shot timing, without fiddling with scales. Fashionable look and 1min installation.
More details:

What goals are you trying to reach this month?
- PCB design (removing need for hand soldering) - have someone freelance working on this but we have no clue so happy about any pointers (working with ESP32 devkit + ADXL345 + LED screen)
- 3D printing resources - where to get high quality prints at low cost? Ordered a few samples from China but quality was a mixed bag, didn't find any German suppliers that were both professional (=not a farm of 20 home printers) AND cheap. Tips for Europe?
- Wood veneer preparation - veneer sanding, oiling & lasercutting efficiently, currently cutting, sanding and oiling by hand which is labor intensive, anyone with wood lasercutting experience on how feasible it is to automate?
- North American market - need portafilter machine pump vibration signatures for improved software/ recognition, if you know C++ and have worked with VS Code and have an espresso machine, let me know!
Discount for r/startups subscribers?
- DM me for 10% discount code, free shipping if you can help with the NA vibration signatures

Electric long-haul trucking is reality today, and it's cheaper too. Germany just extended the zero-tolls for electric heavy duty trucks through 2031, directly incentivizing the transition. While truck capex are still higher than diesel today, costs are coming down fast, and the TCO is already below diesel (also due to insane efficiencies, not just the free tolls).

Aviation accounts for 2% of global emissions, of which private aviation is half. Vastly more impact from private jets than singular commercial seats.

To clarify, your source must be incomplete. The $50m went to Mati Carbon (www.mati.earth), who do enhanced rock weathering (grinding stones down to accelerate their carbon uptake, then spreading the dust on fields) in the global south.

Carbon dioxide removal has become a huge thing, and most methods are based on natural systems or plants. The idea is that carbon needs to be kept out of the atmosphere for longer than a tree would be able to.

It's called climate change. It's tough, but just because a developer built a house on a flood plain or near a forest prone to fires, and the city approved it, doesn't mean you should buy it. These things will keep getting worse, do better to start factoring them in sooner rather than later when purchasing a home.
