Efficient fan

[JohnnyJ]

I have a Creality 6-SE which has problems when running overhang tests. I believe the printer isn't cooling the melted PLA fast enough. I tried a different fan nozzle: https://www.thingiverse.com/thing:5222739 but the result with that was worse.Anybody have a suggestion for a more efficient fan that will fit mechanically and electrically in my printer?

gravity sucks!

At about 88 degrees the threads fall

Perhaps you need to go slower for overhangs which will give the filament more time to cool and set

Nice idea. Is there a command for "when the slope exceeds 80 degrees, go slower"?

Dunno, I think in Prusa slicer if you put overhangs in the search it might come up with something ?
There must be You tube videos on overhang problems.

I never watch YouTube. They all contain one hour of useless bragging when you can read the context message in 2 seconds in a proper post. Thanks anyway!
