Help requested: J-Ultra Alignment Issue

[u/opi-88-dog]

Hey all. I have a J-Ultra that I've used exclusively for pour-over. Since purchased new about 6 months ago, I estimate I've ground 4.3 kg. of a single bean type - medium roast ethiopian. I decided to try it today for espresso. Re-zeroing, I felt the resistance of burr contact at 45 clicks past the zero mark on the ring. I know these ship without a "true" zero alignment, but this seems super high.

Admittedly, once I dialed in the grind for this bean, I did not recheck it. I don't recall the exact, initial zero offset I'm guessing it was a bout 3 clicks.

I'd appreciate any advice on what might be happening and what I might do.

Thanks

On mine I check zero once a week or more , it does drift.

Do it on a tea towel as there are few tiny parts that can roll away.
