They should be aligned then, but it could be tested with the dry-erase marker test. I will link the process, butI want to give you some general need to knows.

For reference, I have the first Gen one.

1. Whenever you remove the adjuster top. (The thing you turn to adjust the grind. When you loosen it all the way.)

a. Use a dry-erase marker and mark somewhere on the top burr section so you can put it exactly the way it was. (Before you lift it up). Not marking it is a good way to mess with alignment because it is only aligned one specific orientation.

b. The threads are very fine. So make sure to be careful not to crossthread them when you screw it back on. Whether you are removing it to clean or whatever.

2. You will want to zero out the grinder. To do this, first thing before you put grounds in. Or when it is completely cleaned out. With the power off and unplugged, tighten the adjuster gently until the burrs touch. You tighten and turn the burrs by hand, I believe clockwise, keep doing it until you hear and feel that the burrs are touching. Then take the grinder setting pointer thing and orient it where zero is.
