However, in Klipper, cornering velocities are configured by specifying
the desired speed that a 90° corner should have (the "square corner
velocity"), and the cornering speeds for other angles are derived from
that.
Klipper implements look-ahead between moves that have similar extruder Klipper implements look-ahead between moves that have similar extruder
flow rates. Other moves are relatively rare and implementing flow rates. Other moves are relatively rare and implementing
