Custom part cooling fan curve #8527

Open katherinehackworth opened 3 years ago

katherinehackworth commented 3 years ago

Is your feature request related to a problem? Please describe. Fan speed can only be set to a given percentage for the part cooling fan.

Describe the solution you'd like The ability to set a custom fan curve, defining part cooling fan speeds based on the overhang angle of the part at that current area as so: fan curve This is similar to how PC users are able to set custom fan curves for their PC case fans as a function of the (usually) CPU temperature.

Describe alternatives you've considered Unsure.

Affected users and/or printers All users with part cooling fans on their printers.

Additional context N/A

From a user experience point of view, I think this would require some sort of tiered UI that allows people to use a simple version first without needing to understand these graphs. Otherwise this setting would not be understood by many users, and some users might bulk at the complexity.

+1 for overhang based fan control, I need 100% fan for overhangs, but 0% fan for the rest of layers with ABS.

I also want overhang fan control, but it needn't be a custom curve. As mrx23dot has said, one setting for any overhangs above a certain threshold would be adequate in many cases, analogous to the overhang speed setting. A default smooth gradient might be better still and a custom curve would be icing, but a basic version would do most of what I need.

Something similar is being discussed in https://github.com/Ultimaker/Cura/issues/5140, Halfshavedyaks.
