You can set different speed limits for each of the print move types. Keep in mind, that during printing, the print speeds are affected by the printer's acceleration and jerk settings. E.g. when printing small models, it's possible the printer will never actually reach the target speeds.
You can switch the preview mode to Speed in order to inspect the actual print speeds after all the accelerations are applied.
As the name suggests, this feature lets you slow down the print speed when printing overhangs, which enables better cooling when it’s needed. The algorithm calculates extrusion overlap with the previous layer and applies speed calculated from the overhang slowdown function.
Users can control the shape of the overhang slowdown function via four input points – each point has an extrusion overlap value expressed as a percentage of the full width, and desired speed on such overlap. The speeds in between the control points are calculated via linear interpolation.
