3.4.0beta2: fan does not start
-
Just upgraded to 3.4.0beta2. Duet3 6HC, Duet3 3HC Exp, Duet 1LC, SBC.
Slicer is configured to start fan at the seconbd layer at 25%. PanelDue says fan speed 25%, but DWC says 0 and the fan is off. When increasing the speed to the requested 15% via DWC it is starting.
Before the upgrade I used 3.3 and one hour ago - directly before the upgrade - it worked.
Forgot to mention that the 1LC is still on 3.3 because I read in another thread that there are some issues and you guys suggested to stay at 3.3 for the tool board.

@martinnyhc Can you check your M563 line in config.g? It should either have F0 in it or no F parameter at all (provided fan 0 is supposed to be controlled via M106/M107 without P parameter).

It's the bed fan, not for the tool.

You have fan1 set as thermostatic, but also bound to tool0 as the part cooling fan. Tool fans cannot be thermostatically controlled.
Which fan do you want your slicer to control? That fan number should be used in the tool definition.

Now I'm a little bit confused. OK, let's wrap it up.
Heater0 and Fan0 are for the bed

The tool fan starts at full speed as soon as the hotend reaches 70°C.What I want to control per slicer is - as susual - the bed fan.

I'm using this for several years now and latest during a print directly before upgrading to 3.4.0beta2.
So I don't really see a problem. Or am I too confused today (already found out multiple times that today is not my day
). -
I think you are using the wrong terminology. I have never heard of a "bed fan"
Generally, you have a "hot end fan", which cools the heat-break of your hot end. It's very common to have that thermostatically controlled.
Then, you have a "tool fan", which you control via M106 and which blows on your printed part.
-
I think we are having a miscommunication on the difference between a hotend heatsink fan and a tool fan or part cooling fan.
The hotend heatsink fan should be thermostatically controlled and tied to the hotend heater.
The part cooling fan or tool fan is the fan that the slicer controls to cool your part as it's being printed. This fan cannot be thermostatically controlled because it would interfere with the slicers fan commands. Do you want the slicer to control it or the temperature to control it? Right now you have Fan1 thermostatically controlled AND attempting to be controlled by the slicer.
I have no idea what you mean by bed fan. Is this the fan that cools your part? If so, then your tool definition needs to change.
M563 P0 S"Hotend" D0 H1 F1 ; define tool 0The F1 in this command is your thermostatically controlled hotend heatsink fan, and this is the fan that the slicer will be trying to control. If you want to use your "bed fan" for slicer control, you need to change this F1 to F0.
-
Got it. Then I just used a wrong terminology.
Then I'll just change the fan for the tool definition.
Very interesting that it worked for years. Lucky me.
Thanks!

Well it would mostly work because the thermostatically controlled fan would just be on when the temp was up which would be when you're printing and when you'd want the cooling fan going. When the slicer tried to control the fan with a M106 it may or may not have an effect though. So if you wanted to print in ABS or something with no fan on, you would have found that you couldn't actually turn it off I think.
-
I printed a lot of ABS and often switched it on and off
Haha. Crazy. -
@martinnyhc But did the slicer switch off the "bed" fan or the hotend heatsink fan? Or were you controlling it manually?
Either way, you see now where the conflict was.
And more to the point, after correcting that, is it now working as expected in 3.4 beta2?
-
It was controlling the "bed fan"
Will check tomorrow. Currently printing the ringing tower.
