  * The maximum buffered steps/sec of the extruder motor is called "se".

- * mintemp and maxtemp. Turn this off by excuting M109 without F*
+ * mintemp and maxtemp. Turn this off by executing M109 without F*
  * Also, if the temperature is set to a value below mintemp, it will not be changed by autotemp.
  * On an Ultimaker, some initial testing worked with M109 S215 B260 F1 in the start.gcode
