Chamber temperature control

I noticed in my webbrowser during printing PETG that Exhaust fan controlls the chamber temperature, and seems to have a target set at 32 degrees by default. Can adjust the target somewhere in orcaslicer?

You can change this in your printer.cfg:

[temperature_fan exhaust_fan]  
...             
target_temp: 32 
...

Set “target_temp” to the value you like.

I am not sure if this can be changed via GCode (in the slicer) somehow.

OrcaSlicer has a provision for controlling the chamber temperature, under:
Filament - Filament- Print-chamber temperature

I believe this is used for active chamber heating and doesn’t apply to the Zero?

I haven’t tried using OrcaSlicer to control the Zero’s chamber exhaust fan so I don’t know if it’ll activate the fan to prevent the chamber from becoming too hot. I’m assuming it activates a heater to prevent the chamber from being too cool.

I use the Mainsail interface to set the maximum chamber temperature to turn on the chamber exhaust fan.
