FAN 0 & FAN 1 allways ON

CozyP · 21 Feb 2022, 20:24

Hello,

FAN 0 and FAN 1, which are the extruder cooler and case cooler fans, are allways on. No matter how I change the gcode, they allways are engaged. Kinda annoying.

Can someone take a look???

May I ask what you're doing here (above)?

Fan 0 is usually/often the part cooling fan which should be controlled by the slicer Gcode and as set in the tool def M563
Maybe you should define it something like this? :

 M950 F0 C"fan0"                              ; create fan 0 on pin 121.out1 and set its frequency
M106 P0 S0 H-1                                   ; set fan 0 value. Thermostatic control is turned off

The second part/fan is monitoring heater 102 (if I read this correctly) Which heater do you want to monitor? I guess H1 is what you want.

CozyP · 24 Feb 2022, 18:34

@gixxerfast
Nothing changed.
I have 3 fans, one PWM for printing cooling and two other fans, one for moterboard cooling and the other for extruder cooling.

Both extruder cooling and motherboard fan cannot be turned off or thermostatically controlled.

I miss something....

@cozyp Can you run m98 P"/sys/config.g" and post whatever shows in the console?

As far as I can see right now, the last M106 is still referencing a heater that prpbably doesn't exists. H100 ?

So just to make it clear:

Fan 0 is part cooling fan, which is controlled by slicer GCode commands
Fan 1 is the extruder fan which is controlled by the temp of heater 1 and should turn on whenever thet temp is over 45
Fan 2 is the controller fan which is controlled by sensor MCU temp that you have probably defined that somewhere?

Here's mine:

 ; Define MCU sensors which will be available in DWC Extra View
M308 S3 A"MCU" Y"mcu-temp" 				; Officially NOT supported on Mini 3 5+ however seem to work
M308 S4 A"Duet Drivers" Y"drivers" 		; This is not really working as it is just a threshold crossing

And I'm referring to those with:

H100 refers to the "virtual heater" and is used to monitor the processor chip temperature. That could be used for the fan cooling the board.

@fcwilt Edit: No it isn't ~~Is H100 predefined as MCU temp?~~

@gixxerfast said in FAN 0 & FAN 1 allways ON:

@fcwilt Edit: No it isn't ~~Is H100 predefined as MCU temp?~~

From the documentation:

The fourth example sets up an electronics cooling fan that starts to turn on when the MCU temperature (virtual heater 100) reaches 45C and reaches full speed when the MCU temperature reaches 65C or if any TMC2660 drivers (virtual heaters 101 and 102) report that they are over-temperature

I can only assume the documentation is correct.

Frederick

Gixxerfast · 24 Feb 2022, 19:48

@fcwilt Yes, that sound reasonable which made me try it as I set it up explicitly.

I changed my config to:

M106 P2 H100 L0.2 X1.0 T30:50 C"Controller fan 1"

When I run that config I get:

 Error: Sensor number out of range

Also, when I look in the code I see nothing that suggests that there exists predefined sensor numbers

The sensor number list that s set via the H flag is checked with this:

 if (hnum < (int)MaxSensors)
					{
						sensorsMonitored.SetBit((unsigned int)hnum);
					}
					else
					{
						reply.copy("Sensor number out of range");
						error = true;
					}

And as far as I can see the MaxSensors is between 32 or 56 depending on board. I am very likely reading something wrong here as it's not very quickly easy to see what MaxSensors is defined to in this case.

Yes it is correct in RRF2. And in RRF3 you can target the virtual heaters by name now. mcu-temp

Is that text from the cooling the board page?

Yes. And it does show both RRF2 and RRF3 options.

https://duet3d.dozuki.com/Wiki/Mounting_and_cooling_the_board#Section_Notes

Gixxerfast · 24 Feb 2022, 20:04

@phaedrux It's from here as far as I can see: https://duet3d.dozuki.com/Wiki/M106

But can you really refer to it via number >=100 in the H parameter ?

I see nothing that implies that.

OK, so with RRF V3 you cannot use +100 to refer to the MCU or other sensor (virtual heater) as I initally wrote far above here somewhere.

fcwilt · 24 Feb 2022, 20:54

@phaedrux said in FAN 0 & FAN 1 allways ON:

It was from the M106 documentation page:

M106

It mentions v3 firmware and references M308 which is where there are references to virtual heater names.

The H parameter relates to the sensor number(s) created by M308, not the temperature sensor pin number on the board.

Perhaps that could be expanded a little to provide a bit more info as to the connection between M308 and virtual heaters, etc.

Frederick

Phaedrux · 24 Feb 2022, 21:16

Maybe just a link to this?

https://docs.duet3d.com/en/User_manual/Connecting_hardware/Temperature_configuring_mcu_temp

In RRF2 the virtual heater number would go directly into the M106 command. But in RRF3 it's a bit more abstracted with M308 creating the sensor first. The entire example is almost out of scope for the normal usage of M106, especially in RRF3.

That looks fine.

It took me to a site that I was not aware of. Is that the current site for documentation?

Is the "Gcode dictionary" site obsolete?

Thanks.

The old dozuki site will be archived and retired at some point I believe.

@fcwilt it hasn’t been announced formally as we’re still tinkering with it, and there’s still a few pages to add, but it’s live and what we are generally using now. We’ll be formally announcing it and posting messages on the Dozuki pages to redirect people to the new site in the next couple of days. It’s taken quite a few months to migrate and update it! That’s why I haven't been around on the forum as much.

hELLO

I updated fan 2.

However I haven't managed to make fan 1, which is the extruder cooler fan stop and turn on when the heater turns on.

If configure that fan to non-thermostatic control can you then set it's speed using it's DWC fan speed slider?
