Hi everyone, I appreciate the help on my last thread. I took some advice and found the alignment appears to be the issue.

When I spin the burrs(power off reaching in) only a small corner touches. The burrs will spin freely to a small point where they touch. I did the dry erase test and it shows there as well. The top burr was completely wiped when I tested, so I’m suspecting the bottom burr is at an angle.

I’ve tested the following: swapping burrs(new set and top and bottom), trying all 3 positions for top burr carrier, deep clean with a brush and Vaccum, adding shims to top and bottom(tried 8+ with no change).

The only thing that has made a difference was leaving the screws lose. If the bottom screws are loose, the contact is normal. However they make a lot of noise and are unstable so it was more of a test.

I’m pretty lost on what to do next, so I’d really appreciate some advice. Thank you all!

Ive had my DF64 G2 for a few months now. It was working great and at some point I took it apart for a clean.

Upon putting it back together, it runs normally, but the 0 point is now towards the top. Originally, it was at the bottom like in most pictures/videos I see. I made sure the 0 point is correct and there is a chirp there.

Around then, it also started taking a much finer grind to produce anywhere near 9 bar of pressure. I used to grind around 15 and get 30+ second shots. I’m now grinding at a 5 and struggling to even hit 20 seconds. I’ve tried several beans, hot and cold start.

I’m unsure if these things are related, but I figured I’d mention it all in case anyone has some advice.

UPDATE:

I checked for alignment and found that I’m only getting 20% contact. For the 80% that isn’t wiping, the burr moves freely. For the 20% there is a lot of resistance. I am trying to add shims, as I’ve tested all orientations of the burr carrier. I’ve had no luck so far, but will update if this is the issue(hopefully).
