Layout Type: Sparse
Layout direction: any
Mining drill type: Electric Mining drill
Electric Pole type: Medium Electric pole, Small electric pole.
I'm playing with the full py suite, but they are not changing the electric mining drill area and medium electric pole area/connection distance. All other layout types are placing the poles correctly.
