+# Most moves will accelerate to a cruising speed, travel at that

+# travel a short distance could nominally accelerate and then
+# immediately decelerate. This option reduces the top speed of these
+# moves to ensure there is always a minimum distance traveled at a
+# cruising speed. That is, it enforces a minimum distance traveled
+# at cruising speed relative to the total distance traveled. It is
+# intended to reduce the top speed of short zigzag moves (and thus
+# reduce printer vibration from these moves). For example, a
+# minimum_cruise_ratio of 0.5 would ensure that a standalone 1.5mm
+# move would have a minimum cruising distance of 0.75mm. Specify a
+# ratio of 0.0 to disable this feature (there would be no minimum
