DF64 101 | Part 1 | What you should do first when you receive your brand new grinder?

[@VoeHermes]

I did some survey about DF64 before I actually purchased it. Your video is the most helpful I've ever found. The spring adjust is so good. Thank you for your effort. Wish you can bring more.

[@CaffeMartellaSingapore]

Thank you for liking my videos 🥰

[@MrMcotoV]

Just wanted to leave you a comment to thank you for the video! I decided on a DF64 and I've come back here quite a few times to clear some doubts. I really appreciate you putting this together! Have a wonderful day!

[@CaffeMartellaSingapore]

Great to know my videos helps!

[@Nordic-bb8nw]

Just did your spring alignment. Sure made a difference and zeroed it in. Very good tip. Thank you.

[@CaffeMartellaSingapore]

You are welcome my friend!

[@SK-su6xk]

Today I received df64. I haven't unpacked yet, but I came across this video and oh gods, I saw it in time. Thank you for that. Subscribed to your channel. I will wait for interesting videos.

[@CaffeMartellaSingapore]

Thank you.

[@TheLychie]

Im so excited!!!! My df64 has been sitting on my kitchen countertop and today I get a break from work so I can go home and finally set it up :D thank you so much. You explain things clearly and in an engineer way that I can understand :D

[@TheLychie]

okay im here- my only question is in 4:46. My default white sleeve was actually pushed all the way up, not down, but was flush on the top of the spring. is that way or your way correct? i tried pushing the white sleeve all the way down as you said but it was hard tightening the collar. So i switched it back to default and it closed fine. also in my machine, i didnt have to manually screw in the screw and tighten the collar. it was already as tight as it was.

Thanks just got mine today, and I got your indicator mod, this video got me dialed in in 2 shots. Still a bit too much retention. But I’m sure it will get better as it gets seasoned. This video is awesome. Thanks again 🙏

[@CaffeMartellaSingapore]

It's a pleasure and I am.happy that my video can help you!

Received my DF64 and QM Rubino today. Applied the steps in this video with 3d mods. Work seamlessly. Thanks CY.

[@CaffeMartellaSingapore]

you must have gotten the machine from my brother David! Rubino is truly an high quality Italian espresso machine that none can match. I mean it's build quality. Ability to make espresso and steam milk is amazing too!

[@bored2dad]

Excellent clip. Thanks for sharing.

[@davidlogan2682]

One of the first things that I do with electric (burr) grinders is to check for oscillation/wobbling in the turning burr/carrier/shaft (without beans in chamber). If it is wobbling significantly, then the seller or manufacturer may need to be contacted.

[@showmak]

How to check this?

[@NeverTakeNoShortcuts]

My experience is that they all wobble quite a bit, at least relative to how far obsessive compulsive espresso people take these things. Perhaps I can start a KZbin channel on testing the run out on espresso grinders, motors, and bearings.

[@JPC326]

Great timing CY. Actually tried around 6 coffees in my DF-64 and noticed something. (tried size 55 to 65 past zero points with awesome results) For the first 2-3 coffees, the grinder had a lot of retention ~ 1g. I assumed this was normal or that I was too soft with the bellow. I found the grinder had very little spring-back action using the bellow. For coffee 4-5-6, pressing a little harder on the bellow got my coffee ground out and I got around 0.1g retention (that's good). However, after using the grinder I noticed my zero points "seem" to shift. What I suspected it that the spring was not all the way through (as you show on your "Part I | Burr Alignment | DF64 " video. meaning the spring-back action is not strong enough to put the burr on his initial position. So I opened gently the grinder and I was right. All the three springs were in the middle of the silicon sleeve almost at the top like you said. I don't know why they don't check this at the factory as it should be an easy fix. Now my springs look like yours. So I removed the spring, aligned them with the sleeve like you did in the video at 12m 46sec, I ensured the springs are now flush with the silicon. Now the spring-back action is way stronger. The problem is when I try to put everything back on, it seems the springs have a lot more tension now (expected) and I just can't find the entry point of the collar. Haha, I may be crazy but it's been 30 minutes and I still can't find a way to screw the collar of the grinder so all is smooth when i try to screw it. I'm not sure what I'm doing wrong but I don't want to force anything. Tried to find the entry point at 8 and 9 o clock but it does not seem to work. Once I thought I got it around 4 o'clock, the collar was screwing but I made about only half a turn before there was resistance. In your video, you seem to screw the collar with one finger so I expect no resistance. Am I doing something wrong or is the entry point just really hard to find the first time ? I will align my burr later as I don't have markers right now, but I wanted to fix the spring sleeve for the bellow :). I hope I won't struggle like this every time I want to clean it. If you have any advice they are welcome, I am a little afraid of the top collar not screwing... it is my first burr grinder Thanks for the video CY.

[@andlep]

Thank you for an excellent video. 👍

[@robertwilliams5618]

Nice video man

[@CaffeMartellaSingapore]

Thank you!

[@IkerZamora]

There are many tips and tricks through the video, so I suggest watching the full thing. But I find myself coming back, so here are the main timestamps: 3:32 Disassemble the collar by turning anti-clockwise. 4:03 Remove the metal part and the 3 springs underneath. 4:17 Make sure that each spring is aligned with its plastic sleeve. 5:46 Reassemble the metal part back and make sure that the springs are well reset. 6:10 Reassemble the collar by slowly turning clockwise while pressing the metal part down. This should not require any force. It should require 4 full turns before it can not turn anymore. 7:09 Find the zero point. With the power turned off, slightly loose the collar and turn the motor shaft with your fingers until the burrs don't touch each other. Mark this as your zero point with the arrow grind indicator. The espresso range is now near 15. 10:21 Optional: season the burrs. 11:41 Other mods, tips and tricks.

[@CaffeMartellaSingapore]

Wow really appreciates this!

[@andrii4545]

Nice video man, thanks. I guess I have a newer version with the normal (not italic) font for numbers.

[@sevenday7404]

Thanks...i am waiting for my grinder...its shipping to germany...

[@dan138zig]

Hello. After adjusting the silicones and the springs I noticed that the upper burr doesn't sit properly, there's a small gap on the left side if you look from the front. And now I can't pull out the silicones anymore because it's already pushed deep to the bottom. Is this normal?

[@chumphmonster]

Can you also do this video for the Gen 2?

[@CaffeMartellaSingapore]

[@victorsangco1420]

im planning to upgrade my espresso experience, what will you recommend when I used to have a Saeco Poemia machine? I want to have a non pressurized machine.

[@CaffeMartellaSingapore]

you can consider heat exchanger. My recommendation is Quick Mill Rubino.

[@Muhammad.911]

Thank you CY. Just got mine yesterday bought as used but the previous owner just got it last July, so quite new. Initially I thought the zero marker was the “bean” logo on top of the spout. Now I know I have to manually find the zero mark myself. About the alignment and maintenance of this Grinder, do you have another video? Also what’s your opinion about some people spraying the beans with water before putting in the beans? Does the water effect the burrs in a bad way?

[@CaffeMartellaSingapore]

I will never put water in the burr. That's my personal opinion. It's steel burr and I am not sure what is the long term impact of it.

[@Muhammad.911]

@@CaffeMartellaSingapore Tq CY

[@CaffeMartellaSingapore]

welcome buddy!

[@Muhammad.911]

@@CaffeMartellaSingapore one more thing, just tried to do the zero point this morning and wanted to ask, does the zero point is when the two burrs “start to contact” which each other which is very2 quite sound, or when they “fully in contact” but still can move and obviously make a sound that we can clearly hear

[@Millilitree]

​@@Muhammad.911 Slowly turn the grind setting until you can hear the grind making contact with each other. It doesn't matter if you play it safer but turning it ever so slightly anti-clockwise to ensure that the contact is as minimal as possible. It is also a good time to check that only the grind setting of zero(Just use a maker or imaginative line) is making the contact mentioned in the video, but coarser setting like 1 or 0.5 is making no sound.

[@oopnkcoo]

i just bought my df64 got a strong metal smell.. so i just ignore it and grind some bean with it?

[@CaffeMartellaSingapore]

Strong metal smell? That is something that I have not experienced before. Can you describe more?

[@oopnkcoo]

@@CaffeMartellaSingapore just unbox my new df64 gen 2. then i smell the grinder have the metal smell at the burr area. i want to wash it but i scare rusty.🤣 so i wondering this type new grinder.. you all just grinder and brew the coffee without washing/clean inside first?

[@CaffeMartellaSingapore]

@oopnkcoo check for signs of wear or oxidising or rust on the burrs. If there are no signs, just grind a few batches of coffee beans and the smell.should go away.

[@chavitavb]

I have a Niche but want a flat burr. Is there really a difference in taste ? Do you think it’s worth having one ?

[@CaffeMartellaSingapore]

I have a niche and specialita and I sold them off and keep the df64.

[@Bowser558]

When you say the espresso range is 15, is that on a 9 bar extraction? Many Italian machines are calibrated higher at factory.

[@CaffeMartellaSingapore]

No that is the starting or suggested starting point t to grind for your espresso on the df64.

[@phonsitj9741]

Hi , I wonder if i change sleeve of the spring after i already alignment will i lose my alignment? Thanks for yr answer

[@CaffeMartellaSingapore]

The sleeve is just to hold the spring in position. As long as the new sleeve does not grip on to the spring, it shouldn't cause any alignment issue.

[@phonsitj9741]

Changing the sleeve position to the bottom as u stated in Video after alignment will not lose my alignment correct? By the way yr video is very knowledgeable for newbie like me

[@CaffeMartellaSingapore]

@Phonsit J Hi thank you for liking my videos. The material must not be causing any friction and its close enough to hold the spring in position without any movements side way.

[@retro1333]

I lost my espresso range in a few weeks. At start I was using setting 15-12 to get espresso now I have to use setting 4 to get espresso. And I checked all the springs , they are as in the video. Idk what happened to grinder..

Thanks for your video, but I met an issue, after adjust the spring like the video, when I set the number to around 3 and turn on the machine, the beans never flow down, and only a little bit powder come out, will you happen to know the reason? Thanks

[@CaffeMartellaSingapore]

3 is too fine. Increase to 10 and slowly decrease the grind size

[@songholmes]

@@CaffeMartellaSingapore thanks, will try

[@yz249]

Hi, I have a question. My df64 arrived recently and after setting the springs flush with their collar the touching point was at about -3. After using it for aeropress today and trying to adjust finer the touch point then ended up at 30. I opened the collar and checked if the springs had moved but they were still fine. After screwing the collar back in the touch point is now at around 11 and no longer goes fine enough for espresso. Any ideas on why it keeps moving /how to fix it or do you think it's faulty? Thanks alot for your videos.

[@CaffeMartellaSingapore]

Touch point should not move that much. I suspects there are beans or coarse ground that are trapped in between the burrs and preventing you from adjusting finer. Turn on the grinder and adjust until it goes back to zero point (where 2 burr touches and chirp) and try again.

[@yz249]

@@CaffeMartellaSingapore i actually found the video where you explained that and it worked, its back to -3 now. Thanks alot!

I don’t think so unless you get a new dial ring indicator to stick it on top

Yeah every different grinder has a slightly different zero point as this is dependant on the 3 springs.

Whats best? DF64, NICHE zero or mignon Single dose?
