/**
 * M140 - Set Bed Temperature target and return immediately
 * M190 - Set Bed Temperature target and wait
 *
 *  I<index>  : Preset index (if material presets are defined)
 *  S<target> : The target temperature in current units
 *
 * Parameters
 *  I<index>  : Preset index (if material presets are defined)
 *  S<target> : The target temperature in current units. Wait for heating only.
 *
 * M190 Parameters
 *  R<target> : The target temperature in current units. Wait for heating and cooling.
 *
 * Examples
 *  M140 S60 : Set target to 60° and return right away.
 *  M190 R40 : Set target to 40°. Wait until the bed gets close to 40°.
 *
 * 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.
