OrcaSlicer and BumbuStudio had auxiliary fan support for quit a long time, but we could just enable the fan at a certain speed for the whole print.
This Pull Request proposes to add auxiliary fan support for PrusaSlicer, with full independant control.
It adds all these settings:
It generates
M106 SXXX P2andM107 P2gcodes if the auxiliary fan is enabled.Finally it adds a new menu in the gcode viewer to visualize the auxiliary fan level.
While the setting "enable auxiliary fan" is disabled, the generated gcode remains unchanged compared to before this PR. Once enabled, only
M106 SXXX P2andM107 P2gcodes are added without modifying the other M106/M107.
