What parameters control whether the Chamber fan comes on in a P1S? Can this be controlled in Bambu Studio? I couldn’t find any setting for it in the Cooling Section
Every setting is in the slicer’s advanced features section
This is on a P1S not an X1
Sorry but I have a P1S, photo is bambu studio settings. (PC)
The chamber fan speed is set by the Filament Start G-Code in the Advanced tab of the Filament profile. It uses the bed temperature to decide which of several speeds to run the chamber fan. An example:
; filament start gcode
{if (bed_temperature[current_extruder] >55)||(bed_temperature_initial_layer[current_extruder] >55)}M106 P3 S200
{elsif(bed_temperature[current_extruder] >50)||(bed_temperature_initial_layer[current_extruder] >50)}M106 P3 S150
{elsif(bed_temperature[current_extruder] >45)||(bed_temperature_initial_layer[current_extruder] >45)}M106 P3 S50
{endif}
The number after the S is the speed, with values 0-255. You can edit this and save as a user profile if you want.
