Trying a faster start print

[ffontanac]

Just trying to modify the START_PRINT macro for a faster print start.

• Set an intial bed temp higher than desired temperature to avoid the PID effect at the end of the warming process, as it takes time.
• Set an initial extruder temp at 100ºC while bed warming up, so when it's time to rise to desired temp it would take less time.
• Set the final extruder temp as soon as the bed temp is 3ºC below desired temp (rises from 100ºC to desired temp)
• Set the final bed temp as soon as the bed temp is 1ºC below final desired temp (stops de initial bed temp above the desired bed temp)

What I'm trying is to coordinate both, extruder and bed, to finish warming-up at the same time and don't have to wait for the extruder after the bed is already hot enough (similar than original firmware).

Trying to play with "TEMPERATURE_WAIT" command but it doesn't seem to work.

• The second M140 begins much earlier than the sensor "heater_bed" reaches the triggering value.
• The second M104 never happen (althought the sensor "heater bed" reaches the triggering value

Is the "TEMPERATURE_WAIT" command working properly in this firmware or do I have any kind of missmatch in the spelling?

Thanks in advance.

Sorry,
Code format fail.

I paste the complete code text (part of START_PRINT macro)
