Layer fan kicking on randomly
-
Hi Guys,
I'm just starting off with setting up my first machine with a duet board and I'm trying to get my fans up and running correctly now.
I've build a vcore-3 500 version in case anyone was wondering.Now I've wired up everything and added a toolboard to make wiring a lot cleaner at the toolhead.
My config is as follows config.gWhat happens is that the layer fan starts up randomly and whenever I adjust the slider to 0 on the interface it runs back up to 100 automatically.
I'm running in SBC modeHere a quick view of what happens exactly
-
Can you copy and paste your config.g into a post? I can't seem to download it.

Nevermind. It seems like your animated GIF was causing some problems on the page.

Can you please send M122 and M98 P"config.g" in the gcode console and copy paste the results here?
The only time I see the layer fan slider behave that way is during a print if the sliced gcode file is constantly changing the fan speed, but your gif didn't look like it was during a print.

@mher Search your gcode file for any instances of M106.

This is indeed happening without running a print. Sometimes it will just stay of for a while and then it'll start running on it's own out of nowhere.

M98 P"config.g"gives no result it just shows up marked green in the console indicating that it was executed successfully. -
When it's running and when it's off, send
M106 P0and see what it reports.Can you check in your DWC settings that the version installed is also 3.4?
Can you send M122 B121 to get a diagnostics report from the toolboard since that's where the fan is connected?

@phaedrux
When it's off:
Fan 0 (Layer Fan), speed 0%, min: 10%, max: 100%, blip: 0.10Shouldn't the min be 0%? Could this be part of the problem?
DWC is 3.4.0

Not sure about that 10%
Try sending M106 P0 L0 and then check if it's still 10% min.
I also notice that you have the PWM freq at Q150. Can you try returning that to the default 500?
Does the hotend heatsink fan behave correctly?
