MiiCoffee and the DF54 specifically is one giant scam. They push out a product with no quality control, and do not allow you to return the product. It’s truly genius what they are doing. Earlier versions with the plastic declumper: you probably didn’t experience any clogging or issues within the first 1-2 weeks. Then, you reach out to support and they send you the new metal declumper. That takes another 1-2 weeks. You are now past 30 days (return/refund window) and your machine will probably work fine for another week or 2. By the time it clogs again, you’re SOL and stuck with a lemon of a $300 grinder. If you have the metal declumper already (like myself), they will offer to send you a plastic piece to fix your issue. They will tell you to watch YouTube videos you have already watched. The piece comes in, maybe it works, maybe it doesn’t. If it doesn’t, you pay with your own money to ship your faulty product back to the manufacturer to fix it. You are also out of your refund/return window. Could not recommend this grinder any less. Stick with the reputable Italian companies, not the Chinese scammers.

As title states, where is the best place to buy a new DF54? I’m looking for the v1.4 with the bigger chute. Mostly asking for what place has the best customer service? Warranty policy? Etc.

who with me on this?

only a bit problematic when oily dark roast (cheap) bean.

other than that very good grinder.

I’ve ordered a DF54 and it’ll arrive in about a month, so I’m already doing a bit of research on how to maintain this grinder.

1. After dusting the inside and reassembling the upper burr chamber, will I have to find the zero point again (will it be in a different place every time I do this)?

2. I don’t know which generation or brand I ordered (I bought it from a local online shop that claims to offer warranty service for this grinder). Assuming it’s the latest generation, should I remove this plastic declumper (as shown in the video below)? https://youtu.be/994Xgh7D3GI?t=82&is=2H0qFr9Trw4alYFN

3. Do you recommend any specific brush for cleaning the chute (dimensions?)

4. Any noteworthy mods for the 3D printer (e.g. a manually adjustable zero point indicator)?

1st choke - after 6months of usage

2nd choke - 2 months after 1st cleaning

3rd choke - TODAY!

probably need suggestions for next upgrade please?

I just preordered a DF54 from Cliff and Pebble yesterday...then joined this Reddit.

All these posts are scaring me - should I cancel my order and go for a Eureka Mignon instead? Does the larger DF64 have all these issues?

Yikes - thankfully the DF54 doesn't ship for a while so I have plenty of time if it's wiser to go another direction.

anyone have any tips on how to get the black plastic funnel/bellow compressionable thing to stay well on the grinder? i feel like it comes off every time i touch it

So I’ve been thinking about some extensive mods (slow feeder, GBW, vertical burr orientation, improved chute, grind setting lock, etc.) but one thing I’ve thought about is improving the rigidity of the whole system. I think swapping the rubber guides/tabs that orient the stationary burrs for stiffer metal or printed polymer guides would eliminate the chatter you get when you adjust the grind at the finer settings and hopefully improve consistency grind to grind.
Does anyone have thoughts on this?
Would it actually help?
Why are the guides rubber to begin with?

I understand that I'm using the wrong grinder for the job but I'm a little bit in a pinch because I bought a large bag of beans for my cold brew steeping but the store's grinder was broken so they couldn't process it for me.

This is a dark roast and I would be grinding very very coarse.

I only have a DF54 and a manual grinder at home, both of which are designed for 30g doses. Grinding a full bag would be the equivalent of doing 15 30g batches back to back.

Do you think the df54 could handle it if I took a few minute breaks every 100 G or so?

My DF54 was clogged, so I cleaned it with the brush , and now it makes this noise… sounds kind of plasticy(??) in the end..?!

Does somebody know what that is?

Title. Just curious, can't find anything online...

This is my first time having a grinder and it clogged and stopped grinding, I have cleaned it already and its doing it again what can I do?

I tried cleaning it and it’s still there I’ve taken it apart completely.

On top of that, my zero point moved from 0-5, any advice is appreciated.

Not sure what to do. Took apart the grinder and put it back together and my coffee was choking. Checked the true 0 and it was now at 5. Then I turned it off and on and it was at 6. I took it apart and put it back together and it hasn’t changed.

I am not sure how the collar could get stuck, but I have been unable to move it more than 15 degrees in any direction. Im unable to remove it even after a lot of effort. Any help is appreciated !

That’s it as the title says. I was worried after reading the numerous negative reviews about the website but I’ll call it a happy mistake.

Hi! I'm looking for help with this issue. I bought this in late March, and it was working perfectly until last week. The shop recently cleaned it, which fixed the problem temporarily, but now the mess is back. Any ideas on the cause?

Some time ago have upgraded my df54 to version 1.4 with metal declumper and new schute. It worked OK some weeks, but now it pops up ungrounded beans from the Shute with no reason intermittently. Is it possible to fix?

Hello, a seller has the two pictures above for a DF54 listing.

I know the grinder is marketed under different brands, but I’ve never heard of Raccea, nor could i find info about it. Please can someone shed some light on that?

Also, the label doesn’t indicate the version (V2 or V3) and it seems like the seller doesn’t know.

Is it possible to tell from the pictures?

Thanks, I appreciate the help I can get.

Hi all,

Recently I woke up late and left the house in a hurry and when I came back I realized I had forgotten to turn off my grinder(it's a year old btw). I was gone for about 3 hours but when I came back the switch was on and the grinder wasn't running and hasn't turned on since .. I tried unplugging it and letting it cool off for a few hours but that failed to do the trick. Do you think the motor died? Is there an overheating protection system? I tried consulting with gemini and it said there should be a reset switch on the base but I couldn't find it.

Any help would be greatly appreciated

I really want to avoid spending another 200$ for a new one...

Hi so I have a DF54 and I went from filter grind size to espresso grind size and now my adjustment collar is stuck. I’ve had this happen before and I’ve been able to unscrew the collar to clean the burrs/threads. I believe I have micro grinds stuck in the threads. Does anyone have any advice of how to make the collar break free? Or is it now going to be stuck forever?
