Vary fan speed based on layer time

[markxu]

Hi everyone,

I'm new here. Straight to the topic. I am trying to set fan speed based on layer time for each layer.
For example,
when layer time between 12∼11 seconds, set fan speed to 10%;
When layer time between 11∼10 seconds, set fan speed to 20%;
When layer time between 10∼9 seconds, set fan speed to 30%;
......
When layer time smaller than 2 seconds, set fan speed to 100%;

Basically, this is the same idea as slow print speed to [x]% when layer time lower than [y]. Use more fan instead of slowing the print speed down. So that the printer do not has to wait for more than 10+ seconds for each layer on thin pole features. This will speeds up total print time by a lot. Maybe even better print if the pole is really thin, like small than 3mm in diameter.

Is there any way to achieve this with simplify3D or with Klipper?

Thanks guys.

While not exactly what you are looking for, I believe you may achieve a similar effect using the Fan Overrides under the Cooling settings
