GCode per filament?

[Tailslide 0]

I have a gcode controllable chamber exhaust fan. I'd like it set different speeds based on the filament.

How do I do that?

If you know the gcode commands that control that fan and you are sure that the firmware understands those commands, then it's possible you could use the "Search and Replace" post-processor to change the fan speed at certain layers.

Your not giving us much to go on so that's a guess.

Yes I know the gcode to use, but I can't figure out how to get cura to apply it per filament. 

I'm only printing one filament at a time.

 

I'm not sure how changing fan speed based on layer helps.. I want to set it per filament.. like if I'm printing ABS I need one speed, if I'm printing PLA I need another speed so I can tune it to not smell but also not have so much cold air sucked in the part warps.
