I need to make some purchases this week. For controls i will be using the Picobotics PicoCNC and the Sure Step STP-MTR-23079 . Can anyone verify that this set up would work? One thing I am concerned with is connecting the motors to the control box. The motors look like they have square connectors while the box looks to accept round ones. I was also thinking of getting the 434oz-in version of the same motor for the z-axis, since it has to hold up a drill. Is this necessary, or should 276oz-in support a drill fine. Finally, can anyone make comparisons between this control box versus the Xylotex box? They seem relatively similar.
