I’ve noticed that in some cases lines that are classified as “Overhang walls” use the bridge speed instead of the overhang speed. See the blue overhang lines here:
Checking the speed of those lines, the color indicates it’s between 37 and 63 mm/s, so it’s likely using the value of 50. It’s also the same color as the bridge lines next to it:
If I change the bridge speed to something lower, like 10, both the bridge speed and the overhang speed change to that value:
This is with Bambu Studio 1.7.4.52. Is this a bug, a misuse of the overhang/bridge terminology, or intended but undocumented behavior?
