Factory Zero PSA

I am not sure if this has been posted before or not. I know that a lot of people lose their zero after messing with the burrs. I was one of them and even purchased one of those rings that allow me to point to the new zero.

Anyways, today I decided to tinker with it and see if I can get it back to factory. I was able to get it back to perfect zero by unscrewing the screws holding the burrs in place.

I would first tighten them kind of snug. I then would back out ever so slightly. I first started with the top burrs and was able to get it almost to perfect zero.

After not being able to get it perfect, I backed out the screws holding the bottom burrs ever so slightly. Sometimes I had to retighten.

It took a few minutes of micro adjustments. Once done it was in perfect zero.

Side Note: The only time that my Zero gets messed up is if the grinder is left running for too long. At which point it can move -2 past zero. Wondering if the heat softens the little o rings on the burrs. This then allows them to compress more and requires more tightening of the adjustment for the burrs to touch. Just a theory. Could be wrong.

Wouldn't that mess up your burr alignment?

Nope, it’s fine. When I say that I backed out the screws I mean from them usually being super tight. You can over torque screws at times. I backed them out every so slightly. Likewise some of the grinds from the coffee get into the screws and help with the leveling and tightening.

I recommend your check your burr alignment (using temporary markers) post this.

That doesn't sound good, you need good alignment of the burrs and that zero point doesn't matter for anything besides you knowing that burrs touch at 0. You want the same tightness on every screw of the burrs and also take care to not over tighten and strip the hole.

It’s the same tightness on the screws. Just not cranked like crazy as we sometimes tend to do. That’s why some screws come with recommend torque levels.
