# Description
Re-Creation of Pull Request #6964 with X1E changes pulled.
OrcaSlicer includes exhaust fan settings for each filaments, however
these settings do not take effect on Bambu Labs machines that include
chamber temperature regulation fans.
Further investigation into the g-code files produced reveals that the
filament start g-code is responsible for using the air filtration
setting and sending the appropriate `M106 P3
S{during_print_exhaust_fan_speed_num[current_extruder]}` command to the
printer. However, this command, even with the setting enabled, is never
written to the final g-code file.
By default, Bambu Lab's filament profiles wrap this command up in` {if
activate_air_filtration[current_extruder] && support_air_filtration}`
clause, which always evaluates to false. As it turns out, the printer's
have the `support_air_filtration` flag set to `0` in the
`fdm_machine_common.json` file.
This change updates that value to `1` in the .json files for the X1,
X1C, X1E, and P1S 0.4mm nozzles. This is then inherited to other nozzle
sizes and user generated profiles. This is done by simply adding a line
` "support_air_filtration": "1",` to the .json to override the inherited
setting.

## Tests
Updated this flag in a custom user config for the printer than tried
generating the code file with Air Filtration enabled and set to 70%
The appropriate `M106 P3 S178 ` appears in the filament start gcode
section of the file.
