Flat bur grinder changes after cleaning (sh.itjust.works)

I disassembled and cleaned my Eureka the other day, my first time doing so, and now what was a “2” grind size is closer to a “4.” In other words, it’s grinding finer overall. I’m guessing something was changed during reassembly? Do I need to recalibrate it or anything? I had notes about grind sizes for different coffees, are these all moot now?

I believe the calibration for these grinders looks something like

Unplug power
Slowly turn grinder by hand while empty
Slowly adjusting grinder knob until grinding plates just barely touch when spun by hand
Adjust dial facade to indicate this is the new "zero" location

Either way, the term "calibration" + the name of your grinder should get you a fairly specific run down.

It's worth noting that if your grinder wasn't calibrated like this when you got it then your notes will indeed need to be redone. But only once because next time you disassemble for cleaning you start at the known zero point again by going through the simple calibration process.
