2 weeks ago By design? Who knows. Myself, I see it as a sign of neglect.
In any case, the behaviour that you observed is 'normal'.
The user @BeauSlim has a mod for the fans found here.
Describe the bug I'm not sure if this is an inherent flaw in the SV06's design, or a wiring flaw, or a firmware flaw, but it seems that the mainboard cooling fan is linked to the part cooling fan. I noticed this when I was printing without the part cooling fan on, and got stepper driver overheating warnings in Mainsail interface.
To Reproduce Steps to reproduce the behavior: Turn the fan off in Mainsail's dashboard. Examine both part cooling fan and mainboard fan for movement. Turn fan to 100% and check on both again.
Expected behavior Mainboard fan is statically set to 100%, or automatically set based on stepper driver temps
What printer are you using?
SV06 with stock fans and mainboard
What kind of device are you using to host Klipper?
Pi 4B running MainsailOS
How did you install Klipper?
MainsailOS
Is your local copy of this configuration up to date?
I installed it yesterday.
What slicer are you using?
PrusaSlicer
Are you using the config bundles from this repo?
Yes
Did you Adjust your slicer?
I used the provided config bundles
Additional context I can't inspect the mainboard right now, as I have a print running. I have a desk fan pointed at the mainboard enclosure, which seems to be doing the trick for now.
