Did anyone notice that the prints don’t start off with 100% chamber fan anymore? I’ve seen 60% and 70%. It looks like they implemented better chamber fan optimizations, but I’m unsure if it’ll adjust based on current temperature/filament type or if it’s just setting the fan lower and hoping the temps don’t rise too much.
If anyone has any further details on this, please do share! Either way, I’m pretty happy with this change because I was reducing the chamber fan speed to 70% for every single print at the start of it in order to reduce the overall noise and didn’t have any temperature issues.

They changed the tests in some of the default filament profiles. You can see this yourself by clicking on the pencil icon for the filament profile, enabling Advanced mode and viewing the Advanced tab. You’ll see something like this:
; 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}
Earlier, this would run the fan at full speed (S255) when the bed temp was over 45.

Ah thanks, this is interesting. Time to check the profiles I’d copied from the previous default settings, because this used to be a similar issue for me - I was always setting the chamber fan down.
