Feature Request: Energy efficient G-code - first heat up bed then Nozzle

[spitzlbergerj]

🐞 feature request

At the moment, Luban generates G-code, where the nozzle is heated first and the bed is heated at the same time. But the bed takes many minutes to heat up, the Nozzle only one minute or two. This means that the nozzle must be kept at temperature for minutes, even though this is not yet necessary.

The solution to this is very simple. First, please heat up the bed. Then, or shortly before reaching the temperature, heat up the nozzle as well. This is a super simple way to save some energy.

Example: Luban 4.1.3

;Start GCode begin
M104 S215
M140 S60

this is a better way

M140 S60
M190 S60
M104 S215 T0
M109 S215 T0

Let's make the world a little better :-)

This might have the additional benefit of keeping the hot end fan off just until starting to print to keep the noise down.
