Strange fan problem

[RogerL]

Hi,
I Duet wifi and I supply it with 24v
I have a E3D v6 24v setup and corresponding e3D fan for hotend.

All has been running great until the fan stopped, I have tested another fan and cables with no luck.

The I took a multimeter and measured voltage on FAN1, it shows 12v.. I have not changed anything.. It should read 24v, right. FAN0 gives 24v..

Can someone explain if Im being stupid or if something changed.. To make it even odder I tested with another Duet Wifi but with same config card.. same result 12 v on FAN1

are you sure that the multimeter is working?

have you measured the voltage of the powers supply with that multimeter?

@Veti
Yes I did, its working.

Just because I wrote this post it now turns again.
Whatever fixes the problem is good

@RogerL

i would suggest you check the wiring.

maybe there is bare wiring, or the wire is not making good contact
