Fan Wiring on Duet 2 Wifi
-
I have a problem with my fans. I connected 3 fans to fan0, fan1 and fan2.
Duet Wifi 2:
fan0 = Layer Fan
fan1 = HotEnd Fan
fan3 = MCU FanThe associated area in config.g looks like this:

Thermostatic control is turned on ; Tools M563 P0 S"Nozzle" D0 H1 F0 ; define tool 0 ...War vorher F0:1On first layer without running Layer Fan an running HotEnd Fan
The graphic in WebEnd say: OFF or 0 for booth Fans (Layer and HotEnd) ... but HotEnd Fan is running correctly and only the Layer Fan is off ...On Layer 2, when the Layer Fan start ... the values of both fans go up. But Synchronous.
I can then move the controller manually (it doesn't matter which one) the other one always works in sync. The real fan reacting to this change.But that's not supposed, because I only adjust the layer fan.
Why is the Tool Fan also misaligned (syncron) in the graphic?And the Second Problem ... I don't see the MCU Fan in WebEnd ... but it works correctly.

thermostatically controlled fans don't shown in DWC and are not controllable.
The tool fan is the fan of the tool that is active. Hence why they both change the same.
If you have 2 tool and tool 1 was active, then the tool fan would be the same as fan 2 (or whatever fan is used for tool 1).
You can hide the tool fan so only fan0 is showing

hello jay my friend
Does that sound like everything is completely normal and intentional?
So is not a bug ... but a feature

The DWC generates a slider for the "layer" fan for the current tool.
With a single tool you see sliders for your "layer" fan and the current "tool" fan - and they stay in sync.
But if you had multiples tools you might have multiple "layer" fans.
You might see multiple "layer" fan sliders but only the one "tool" fan slider which would be synced to the "layer" fan for the current tool.
If you wish you can turn of the display of either one of the two fans.

2 people say the same ... then it will probably be so right: D
thank you both ... then I can stop my writing in the config
