class vpype_gscrib.renderer.fans.BaseFan

Bases: ABC

Base class for controlling machine fans.

abstractmethod turn_off(ctx: GContext)

Deactivate the fan system.

Generates G-code commands to stop the fans.

Parameters:

ctx (GContext) – The G-code generation context

abstractmethod turn_on(ctx: GContext)

Activate the fan system.

Generates G-code commands to turn on the fans.

Parameters:

ctx (GContext) – The G-code generation context

class vpype_gscrib.renderer.fans.CoolingFan

Bases: BaseFan

Provides basic fan control

turn_off(ctx: GContext)
