The macro box is mutually exclusive with the solver algorithms. It’s only for if you have a set sequence of actions that you want to always use, unconditionally. Miqobot will handle starting the craft and hitting the buttons, but you have to tell her which ones to hit.
The solver – which, generally speaking, is often the better option unless you’re doing very underlevel crafts – will instead calculate the optimal actions to take at each step in order to maximise quality and still guarantee craft completion. With the solver, Miqobot will not only handle starting the craft and hitting the buttons, she’ll intelligently decide which buttons to hit when.
The recommended solver preset is good for most crafts, balancing between calculation time and memory needed vs maximising optimal results. Personally, I use 2:1 chunks, manipulation, and innovation, but I leave waste not turned off. If you want to use the macro for manually assigning steps for whatever reason, untick the “use” box in the solver section. Otherwise, just set the craft count, hit start, and leave it to Miqo.
