+# Description:  This plugin overrides probing command and inserts code to ensure
+#               previous probe measurements are loaded and bed leveling enabled
+#               (searches for G29 and replaces it with M501 & M420 S1)
+#               *** Assumes G29 is in the start code, will do nothing if it isn't ***
