Firmware problem MMU2s

When the selector block fails to find the correct station, the filament will be extruded from a hole not covered by the block.  IE: selector is at station 5 filament comes from 3.  The machine asks that the filament be cleared and on doing that attempts to load the correct one - Filament 3.  However - it does not ensure the extruder block is at the right temperature first - which can result in a jam if the filament enters the block as it is cooling.  This needs to be corrected in the firmware.
