Hoon, appreciate the time and the assistance! RDT is by far a must for the 64v. I have been plahing around RPM area 1200 - 1600. I think the lower has been more consistent. I too have been choking when the shot, almost to the point where it stops. That has been what I have been noticing, and not sure if the grind size + tamp. So, based on what you adjusted from coarse to more fine, that seemed to be better for flow. I have some things to work on. Thanks Hoon! -- Jon

14-16 grind size for my Pesado HE and around 18-20 for my IMS competition basket. But I think I have to adjust the zero point after a few months of use - so maybe a bit lower numbers for both after this adjustment. Great grinder but would have loved the plasma generator on it.

My v2 is set to 10, and the coffee is super coarse. As a result there is all kind of splattering and stuff. It’s set to 900rpm. Ideas? It’s light roast

Very interesting and enjoyable video!

It’s usually between 10 to 15 for my medium roasted beans on df64v.

Hi, have you encountered stalling issues with the DV64V? I hev seen you a few reviews that mention stalling when using low RPM.
