I came here to ask this question too! I have a 6cm x 10cm void to bridge (I know that’s big, but the attached photos are just test prints for a larger design, so I can't print it flipped over 180).
The only thing getting in my way is not being able to change the direction of the initial bridge layer. Nothing will force them to stop laying diagonal first layer, and my printed version of this test print shows that my settings can work with all but the longest of diagonal stretches. I just need to be able to tell it the first layer needs to be 90 degrees.
