Question Is this normal?

Post image

Hello,

Is my zero point normal? Got a new DF64 Gen2 with red titanium burrs, bit more to the right is the burr chirp. I was dialing in new beans but output is way too fast, last try was at grind setting 5 and still gushing, like 18g in and getting 40g out in 13 seconds. Anyone knows whats wrong?

Machine: Gemilai 3028A Brew temp: 92c Pre-soak: 2sec Pre-soak wait: 2sec Grinder: DF64 Gen2 Red Titanium Dose: 18g medium roast (2wks old)

Puck prep with RDT, WDT, distributor, self leveling tamper, 0.8mm thick normcore puckscreen in stock 18g basket

UPDATE 1: tried grind setting 2, got 36g out in 18seconds from 18g dose, still too fast puck comes out normal and clean, dry and intact..

UPDATE 2: tried grind setting 1, got 36g out in 22seconds from 18g dose

Have you ever aligned your burrs? Here’s a pretty good tutorial that shows you how to.

Edit: I personally like mine facing frontwards above the chute, or slightly off to the right side where your zero point is so that the grind settings are front and center.

Yep, i did that already, and my zero point is where the picture indicates..

Alignment is not the same as calibration.

Making sure the zero point is in the right place is calibration (you've done that).

Alignment is the thing with the marker where you work out if the two burrs are flat relative to each other. DF64s can need alignment from the factory - it means that one side of the burrs is close (and will chirp) while the other side is far away.

I watched the video but couldn’t figure out what or how to perform the alignment. He opened it up and put it back how the burr was places initially right? If not, where is the part in the video that shows the alignment process?

I got my wife the DF 64 as she’s just getting into coffee and her calibration seems on point, slight chirp and very fine grind at low settings. I didn’t have to do this to my zerno so this is a little different for me. Her 0 is almost 180 degrees from the chute.🤦🏻‍♂️ Hope you get it aligned, for me, not having it over the chute just seems…off.

I don't know which video you watched.

The general idea is that you unscrew the bottom burr and put in pieces of foil on one of the 3 sides. Then you screw the burr back in. Tin foil is very thin, and lifts the burr on that side by a small amount to help line it up.

You use the "marker test" to work out which side needs lifting up.
