The default part cooling fan for Hemera Direct Extruder is directly set up against the Extruder Motor. This causes Electro Magnetic Interference (EMI) with the Part Cooling Fan (PCF), and the PCF doesn't function properly.
The problem is demonstrated here: https://youtube.com/shorts/ScPs9Ft-meA
With this mod, you can lift your PCF to eliminate EMI issues, and the PCF can run at full throttle. Check the photos to understand better how the build will look after assembly.
I have tested this with my E3D Tool Changer, and it works great!
