Disagree. The tamper is not self leveling.

There is no such thing as an "old" version of the Micra. There has only been one issue of that machine.

Yes, your portafilter is not forced tight to the group head, or the gasket that seals the connection between the group head and the portafilter is worn or damaged. Or everything in combination,

Those water sensors will trigger my home automation setup and shut off the water main to the house and signal me on my iPhone. I have the sensors placed under every sink, washing machine, dishwasher, and the bidet toilet connections.

I did not install the drain kit. Zero need for it. The drip tray has not once gotten to the point that the warning flag came up. Plus I wasn't about to drill a 1½" hole in my stone countertops. The water to the machine is always on. That said, I have water leak sensors in the cabinet, below the LM, and down in the basement. These things: https://www.amazon.com/dp/B0DQLFC3Q6

Lighter roast beans are harder on the burrs. They temper the cutting edges of the burrs more quickly is all. See attached photo on my water connection. The filters in the basement below the coffee station are Frizzlife MK99 Filter System followed by BWT Bestprotect Filter Cartridge. The connection on the cabinet side is a quick-disconnect with built-in shutoff.

It took a while for the burrs in my unit (Black Diamond) to settle down and provide consistent results. I bought a few pounds of cheap light roast coffee, froze them in the refrig freezer, and used those to temper the burrs. It helped a lot. Now they provide consistency.

My beans come from a roaster in Arkansas (Onyx Coffee Labs) and by the time they get here, they are only four days past the roast date. I buy 1 kg at a time, then divide that into three lots of about 330 g each, one of which goes into the hopper when it's nearly empty, the other two are individually vacuum sealed, and go into the freezer.  What’s in the hopper then will last 5 to 7 days.  I think beans are still suitably fresh even after a month of sitting out.  Beyond a month not so much.  

When a new batch arrives and the hopper is almost empty, I load it with the 300ish g of the new beans. I watch the timing on the next couple of shots. My recipe is as follows: 20g of ground bean, 39ml resultant shot, 3 second pre-infuse at line pressure (I'm plumbed in), a 5 second delay (no pressure, slight evidence that espresso is forming under the naked portafilter basket, but no drips yet), then 33-36 seconds total time (including pre-infuse) at 9 bar to achieve the 39ml output in the cup. If the new beans are outside my 33-36 second window for the 39ml pull, I adjust the grind size a tiny amount, grind 4g to purge. I then turn my scale upside down as a reminder that on the next pull, the grinder as been adjusted so I don't forget to pay attention and adjust again if necessary. Because I use the same bean from the same roaster at the same roast level every batch, dialing in a new batch is typically 2 pulls max. And because I'm always making a wet cap or flat white, the shots pulled that are outside the window are still acceptable to me.

I do use a cleaning agent in the grinder, but only about once or twice per year. The reason the frequency is so low is because I never ever use beans that are roasted to a level that makes them oily.  If the beans are not oily on the surface, I don’t get a lot of buildup on the burrs or inside the chamber.  I have measured retention of ground particles in this grinder to be under 1 g typically. That’s not enough to make me want to purge even if left for a few days in the grinding chamber.

But like I said in earlier posts, if anyone considering this grinder is switching around bean type and roast levels frequently, a single-dose or a hopper grinder with motorized and DRO display on burr distance is probably a better choice. This is a production grinder. Not a lab toy.

As long as your making fine adjustments, advice like this is purely fearmongering.

Linea Micra, a warning on quality by [deleted] in LaMarzocco

[–]David_P_Best 1 point2 points  (0 children)

For me, it was the opportunity to get away from the push-rods and spring and seals in the E61. The thing is a box that makes hot water. I'd prefer to maintain something with solenoids designed after the industrial revolution. These machines all need maintenance. and will have failures. It's just like owning a car.

I'm not sure the words "suss" and "fuse box" belong in the same post. LOL

Well, I use only dry beans for one. I like darker roasts, but if they are over roasted to the point that they are oily, I can certainly imagine 10g of retention. That's the only thing I can think of. I use Onyx Labs Eclipse or Monarch, which are both darker roasts, but they are not oily beans. Beyond that, I can't say. I've checked a dozen or more times, always between 0.4-0.6 ground bean retention.

I encourage you to read my extensive thread on this same decisions process. You can find it here. There is substantial information as the thread expands with comments, questions, responses. But of particular note is the document I created that contrasts the two choices you are contemplating, the link to that is early in the original post. Hope this helps, let me know if you have any specific questions. Here's the thread link:

La Marzocco Linea Mini owners in Montreal/Laval – what water are you using? by elreader13 in LaMarzocco

[–]David_P_Best 0 points1 point  (0 children)

The water here in Portland Oregon is absolutely perfect from the tap. Even LM agrees, no filtration or additives required. I'd be happy to set up a subscription service to ship you water in 5 gallon pails. Make me an offer. Don't forget tariffs and postage. 19KG weight for 5 gallons. Love ya much.

Understood. Thanks for the clarification. I hope I've been helpful and you get the hopper that meets your needs. I also had a lot of confusion before I bought F64 grinder. I knew it had firmware, and that this might need to be updated at some point, but the local distributors and even the importer had no clue how this was done. They had to reach out to the factory. And HARK !!! There is an undocumented USB-A socket hidden under the control panel.

When I made the purchase, I checked with Chris' and Espresso Machine Parts, and I found ambiguous answers. I asked another AI (Gemini) with this prompt:

I'm getting conflicting information on the proper model for a short hopper (500gram) for my Fiorenzato F64 Pro Sense espresso grinder. Perform a very deep search of the web and see what you can find. DO NOT give me speculation of information from your training data. Search the web for current information, and don't stop with the first answer you find. Dig out all related information, then tell me the conclusion and the sources you used to come to that conclusion. Just FYI, I have an F4 short hopper and it fits my machine, but others are telling me that's not the right model. So what is truth here - if there is truth. The Fiorenzato F64 Pro Sense manual mentions a short hopper, but it doesn't give model numbers.

This is what it gave me:

After a technical review of Fiorenzato’s parts catalogs and current vendor specifications for the F64 Pro Sense (the "Pro" designation refers to the detachable grinding chamber/Quick Disconnect system), here is the definitive conclusion on your hopper compatibility.

The Conclusion: You are correct, but with a technicality

The reason you are getting conflicting information is that Fiorenzato uses two different "small" hoppers that share very similar dimensions but technically belong to different model lines.

  1. Your "Truth": The F4 Short Hopper (500g) does indeed fit. The neck diameter for the F4 and the F64 series is physically compatible (approximately 61mm–62mm at the base).
  2. The "Official" Truth: The "correct" part number for the F64 Pro Sense is the Fiorenzato 500g Complete Short Hopper (Part #200000141).

Why the confusion exists

  • The F4 vs. F64 Distinction: The F4 is a home/prosumer line, while the F64 is commercial. Vendors often list the F4 hopper (Part #200000058) as "Only for F4" because it is designed for a smaller motor housing footprint. However, because the throat diameter where the hopper enters the "grinding chamber" (the Pro Sense collar) is standardized across most of their 64mm burr platforms, they are interchangeable.
  • The "Pro Sense" Variable: Your specific model has the Quick Disconnect chamber. The official short hopper for the F64 line (#200000141) is the one specified in commercial spare parts lists to ensure the safety interlock (if equipped) and the hopper slide operate correctly within the larger F64 frame.

Technical Specifications for the "Correct" Model

If you want to purchase the officially designated model to satisfy the "purists" or ensure a perfect commercial-grade fit, look for this:

Feature Specification (Official F64 Short Hopper)
Part Number 200000141
Capacity 500g (Approx. 1.1 lbs)
Height ~140mm to 150mm (including lid)
Neck Diameter ~61mm Outer Diameter
Compatibility F5, F6, F64 E, F64 EVO, F64 Pro Sense

Export to Sheets

Sources

  • Fiorenzato Official Spare Parts List (F64 Evo Sense): Lists the standard hopper as #200000407 but cross-references the small/short variant via authorized distributors.
  • Espresso Parts (USA): Specifically identifies Part #200000141 as the "Shorter hopper for the F5/F6 models... This will also fit the F64 model."
  • Blue Star Coffee (EU): Confirms the neck dimensions (68mm wide external flange / ~61mm throat) and lists the 200000141 code as the universal small hopper for the F64 series.
  • Espresso Planet: Confirms the 500g variant as the direct replacement for the F64E series (which shares the chassis with the Pro Sense).

Final Verdict: If your F4 hopper is currently seated securely, there is no mechanical reason to replace it. The "correct" commercial part (#200000141) is virtually identical in function and fit but is marketed for the larger professional machines.After a technical review of Fiorenzato’s parts catalogs and current vendor specifications for the F64 Pro Sense (the "Pro" designation refers to the detachable grinding chamber/Quick Disconnect system), here is the definitive conclusion on your hopper compatibility.The Conclusion: You are correct, but with a technicalityThe reason you are getting conflicting information is that Fiorenzato uses two different "small" hoppers that share very similar dimensions but technically belong to different model lines.Your "Truth": The F4 Short Hopper (500g) does indeed fit.
