I am trying to improve the resolution of my Shapeoko 3 in order to minimize the stair step I see in aluminum on faces that are not parallel to either X or Y. I have thought about it before and it was brought up in another thread that the first option may be to swap out my steppers for 0.9 degree rather than 1.8. My issue is that I do not know enough about the electrical considerations when picking a stepper. I know that the existing steppers are 1.8 degree 125 oz-in NEMA 23’s and that is about it. Here are my questions:
Do we know the max amperage of the controller? I vaguely remember it being 2A
Do I have to worry about inductance or voltage specs on a stepper?
I have looked at this stepper before:
I didn’t take the time to determine if it was the right choice then. I would appreciate it if someone would take the time to explain the electrical specs to me. I have a slightly better than a novice level of understanding when it comes to this kind of thing.
