Positioning resolution?

What is the minimum Step Size for the SnapMaker 2?
i.e. If the stepper does a single step, how far does an axis move?
I saw one person say they thought it was 0.08mm, but I’d like some confirmation of that.

The single step for the stepper is 0.03mm for the Snapmaker 2.0.

Does it do micro stepping?

The math does not work out for a 0.03mm minimum step. What is the lead on the linear module leadscrew and the micro step setting please?
