Hi,

I made a mistake: it is hot hend fan who doesn't work, and it is connected on PWM.
Both extruders turn wrong way (filament goes out) what to do ?

Thank you for your answer

I am having the same issue with the hot end fan on a G2S. Was there a solution to this?

No sorry. No answer for the moment.

hot end fan (pwn-fan) is controled by g-code.so it's running according to the code.

my extruder fan does not turn ever - result overheating and melting of hotend. When does g-code turn this on?

Where in g-code to correct this?

I use the settings in SLIC3R to turn the fan on.. It's in one of the tabs (I'm not in front of my computer with the program). I have it set to always turn the fan on and keep it at 100.

Thanks for tip but i tried that and fan never turns on. Is your fan two or three wire. I.e. yellow wire as well to fan?

The hotend fan only has two wires,as pic bellow. you can swap the fan with coldend fan to check if the fan was dad or not .
