+## Written by Steven Morlock, smorloc@gmail.com
+## Modified by Ricardo Gomez, ricardoga@otulook.com, to add Bed Temperature and make it work with Cura_13.06.04+
+## Modified by Stefan Heule, Dim3nsioneer@gmx.ch, to add Flow Rate, restoration of initial values when returning to low Z, extended stage numbers, direct stage manipulation by GCODE-comments, UltiGCode regocnition, addition of fan speed, alternative selection by layer no., disabling extruder three

+# M220 S<factor in percent> - set speed factor override percentage
+# M221 S<factor in percent> - set flow factor override percentage
+# M104 S<temp> T<0-#toolheads> - set extruder <T> to target temperature <S>
+# M140 S<temp> - set bed target temperature
+# M106 S<PWM> - set fan speed to target speed <S>

+#history / changelog:
+#V3.0.1: TweakAtZ-state default 1 (i.e. the plugin works without any TweakAtZ comment)
+#V3.1: Recognizes UltiGCode and deactivates value reset, fan speed added, alternatively layer no. to tweak at, extruder three temperature disabled by '#Ex3'
