CPU fan - Bushmills/Sovol-SV08 GitHub Wiki

The CPU fan runs continuously on 100% power. This is due to a flawed configuration, and easy to fix using the instructions from this Youtube video.
Short version: Open Klipper web frontend, go to "Machine" configuration menu item, select "printer.cfg" file, create a copy, then go to line 375, where this section can be found:

[fan_generic fan3] # exhaust fan

max_power: 1.0

replace the whole section against:
