I mean it registers movement of ~0.1mm as the spindle turns. i.e attach the indicator to a chuck, don't attach a probe and switch the mill on low speed - the needle moves as much as 0.1mm as it revolves.

I'll have to check again, but I think the needle jumps at the same position during rotation, which I think is therefore a defect.
