You need quite the opposite, more cooling on those overhangs. As you are in the chamber, the heated air wont cause warping like outside an enclosure, so crank those speeds on overhangs. I generally run 80-100% on bridges anf steep overhangs. I do also slow down print speed on overhangs significantly to allow more cooling aswell

May i see both of your works?? Id love to give em a read!

it sounds like you need to invert the runout sensor detection, as it is triggering immediately.
