Seems reasonable from a p64 owner

The stalling issue is real, I'm afraid.

I just attempted a low-RPM grind for pour over, and the DF64V stalled immediately. I twice had to disassemble to clean out the burrs. The only way I could complete the grind was to hand-feed the beans a few at a time, which took forever. I'm willing to live with low RPMs being off-limits for espresso, but it's not acceptable for filter coffee. I'm waiting to hear back from Joe Kolb on whether the new control board helps with stalling, and how to tell if mine has the older version.

It would be really interesting to hear if the 220-240volt variant suffers the same stalling issue.

Are there any 220-240 volt df64v users out there who are able to comment?

Unlikely, there very few grinders with plus 200w motors that dos and when these do it's usually hopper fed.

The grinder doesn't seem ready for prime time. Surely they tested all the grind speeds before slapping V on the box? I understand a cheaper grinder struggling with a grind outside of its designed spec, like a filter grinder stalling on ultra light beans trying to grind for espresso. Stalling on filter with stock burrs and unmodded grind speeds seems like they need to go back to the drawing board.

I've received reports complaining that this thread has been derailed by a long-running "early production run problem" debate.

So, to help keep the [problematic?] early production run discussion separate from the [working?] grinder experiences, I've split the former off to a new thread: Turin DF64V Disappointment. It's not a perfect split, but I did try.

Going forward, please try and keep these topics separate so those not having "out of the box" troubles with their grinder can share their experience here while those who are working through troubles can commensurate and share resolution strategies there. Here's hoping the latter thread will end happily for those having troubles with the Turin DF64V. Thanks.

It's now known that all the early reviewers also received units with pre-preduction boards. Stalling issues can be attributed to the defective board but also due to the built-in failsafe to protect the motor. Until the new boards are shipped, it's all speculation.

Joe Kolbs announced that everyone with a pre-production DF64V is getting the new board.

To be clear the only explicit claim Joe has said about the control boards is that some had an issue with the safety reset. This could be the cause of some experiences with the unit appearing wholly defective, but at face value does not mean it has anything to do with stalling/failsafe kicking on.

Joe has been asked if the stalling is related to the control board but afaik the only direct answer to that question by him has been "Could be related".

These df64v threads have been a mess, abound with wild speculation and misrepresentation both for and against this grinder. We would be better served if we could be more objective and minimize speculation going forward.

I have a 220-240V version I am testing for a UK retailer. I'm mainly doing an engineering test. I believe the grinder is now about 4 weeks old, at least I believe it was air shipped shipped to them 4 weeks ago....then they sent it straight to me.

I tried it on a filter grind at 600 rpm and a cold start with 24g beans in the hopper. It ground no problem. I've tried espresso at 800 to 1000 rpm, it did do a cold start, but I don't think it was super happy. There was sometimes a tiny fraction of a second delay before it got going. In fairness, the user guide does recommend it's running, then beans are tipped in...something I would recommend!

Once going and grinding it's never stalled out, or sounded like it's going to. It's almost silent when running empty (which can cause you to walk away and leave it on, no auto stop), but quite a harsh high pitched sound when grinding. I've seen some influencer reviews and there are a few things they have omitted to mention, which I suspect are not a peculiar trait of my test grinder. I'm using it for a while to try and see if any problem develops over time.

I hope they sort the problems out for the USA if they are related to US grinders, as it's a nice little unit, very small footprint and would suit a lot of people. It seems quite well manufactured where it counts.
