Aux-Fan Fluctuates

Hi everyone,

I’ve recently noticed that the auxiliary fan speed has been fluctuating.

I’m printing with Bambu PLA using the default settings. The fan is set to 70% in the filament settings.

During printing, however, the fan fluctuates between 70% and 80%. At least, that’s how it’s displayed to me in Bambu Studio and Bambu Handy.

Can you see something similar?

Thanks and regards

Not the same thing but when changing speeds i saw those changes in the past.

I think they show set speed and some kind of real/measured speed when there is a diffrence.

You could try 5% lower speed to check if its gone (rpm could be near where it will show 10% more or less) or if maybe your fan has some problems moving dirt/malfunction then check for that.

Hello everyone,

I’ve actually noticed the following. When I print with the door closed, the auxiliary fan starts to fluctuate between 70% and 80% after an indeterminate amount of time. When the door is open, this behavior no longer occurs.

The P1S doesn’t have a door sensor or anything similar, does it?

Does anyone have any ideas?

Thanks and best regards
