FAN 0 & FAN 1 allways ON

@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.

@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.

@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.

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.

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 new documentation site went is live now.

https://docs.duet3d.com/

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

I didn't even know it was planned.

Thanks.

@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.

At first glance it looks grand.

Thanks much for your efforts.

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.

@cozyp

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

Frederick

Phaedrux

Or send M106 P1 S1 H-1 That should turn it on full blast.

CozyP

@fcwilt I have connected this fan in the non PWM fan output

CozyP

@phaedrux That's the problem. The extruder fan, NOT the part cooling fan is running full blast. Allways. Usually these fans turn on after T45celcius automatically

Phaedrux

Sorry, can you clarify which fan is connected where?

What happens when you send M106 P1 S1 H-1 ?

Sorry but I don't understand what you mean by that.

I was wanting you to verify that whatever output you were using was still working.

Frederick

@phaedrux @fcwilt

Ok. First things first.

Phaedrux, I sent M106 on config file. Nothing changed. Fan stays ON no matter what. FAN 1 was added as option on DWC screen, but it cannot be controlled, which is correct, as the fan is connected in a non PWM output.

dcwilt, the extruder heater fan and the motherboard fan are connected in a NON PWM output, but they allways stay ON, full blast no matter what....
I wanted to turn them on via thermostat, as they should work. Am I missing something???
