partscooling-fan not working at all

[SebastianM]

Good morning from Germany!
Yesterday I received my A10 (new version with filament sensor) and the first print went very good. Unfortunately, my partscooling-fan does not work at all.
Neither when I print the sample gcode (A10_dog.gcode) nor when I set it in the menu to "255" (menu control / temperature / fan).
No reaction from the fan at all...

thx in adavance...

PS: This isnt my first 3d printer, so I know what I am doing )

Hello.


So, in the first step I would check the correctness of the connections.
The second step is whether there is a voltage on the fan's cables after the fan has been driven.
Check the 12/24V fan type and compare it with the control voltage.

ehm... where exactly are the pins for the parts-fan?

Update: I played a bit with the cables and now it seems to work...
I will keep an eye on it.

thx!

Check the slot on the extension board first (seems you got it).
So it might be the poor connection?

Exact same problem here, with new A10 (GT2560 v3.0 mainboard).
Proposed solution (play with cable) does not solve.
Any idea ?

Thanks

I got a replacement Fan...
