Part cooling fan not turning on
I recently noticed that my Prusa MK3S is not having the part fan turn on when printing. I have the Auto Cooling feature in Slic3r enabled, and the Keep Fan On feature as well.
I can manually tune the fan to be on when printing but it will not automatically start at any time during the print. So I know the fan is connected properly.
Anyone have this problem before?
RE: Part cooling fan not turning on
There are several settings that can turn the fan off. Small models, dont use fan for for first xx layers etc.
If you save your project as a .3mf file (save project from the menu) and zip it up and attach it we can have a look at the settings you have used to try and figure out whats happening.

I'm also having this issue on my ender 3. I can turn the fan on with the controls on the printer and walk away, when I come back moments later it's off again. Doing a larger print now with many difficult overhangs and I hope the auto fan kicks on for the bridging or this will be a wasted spool

I noticed this too. But since my PLA wouldn't stick I turned on the fan and it help make it stick. How do I get it to turn on for the first few layers?
