/**
 * M104: Set Hotend Temperature target and return immediately
 * M109: Set Hotend Temperature target and wait
 *
 * Parameters
 *  I<preset> : Material Preset index (if material presets are defined)
 *  T<index>  : Tool index. If omitted, applies to the active tool
 *  S<target> : The target temperature in current units. For M109, only wait when heating up.
 *
 * With AUTOTEMP...
 *  F<factor> : Autotemp Scaling Factor. Set non-zero to enable Auto-temp.
 *  S<min>    : Minimum temperature, in current units.
 *  B<max>    : Maximum temperature, in current units.
 *
 * M109 Parameters
 *  R<target> : The target temperature in current units. Wait for heating and cooling.
 *
 * Examples
 *  M104 S100 : Set target to 100° and return.
 *  M109 R150 : Set target to 150°. Wait until the hotend gets close to 150°.
 *
 * With PRINTJOB_TIMER_AUTOSTART turning on heaters will start the print job timer
 *  (used by printingIsActive, etc.) and turning off heaters will stop the timer.
