carriage
retrace_knee_speed
rknee
Platesetter_VLF
Used to control non-linear acceleration during turbo retrace. The carriage acceleration decreases as the carriage reaches its peak velocity. The kpseed parameter can be used to
adjust the velocities at which the acceleration changes. Normally not changed
from default. If set to 0, the optimal kspeed is calculated (about half the
maximum speed). Changing knee speed can significantly slow carriage
acceleration and lead to carriage stalling.
