FAN 0 & FAN 1 allways ON

[Gixxerfast]

@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.

Is that text from the cooling the board page?

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.

It's back like it was before!

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.

@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???

Yes, M106 P1 S1 H-1 will disable thermostatic control and turn the fan on. Send M106 P1 S0 to turn it off again.

Fan1 port is indeed PWM controllable.

Fan0, Fan1, Fan2 are controllable. Plus two more always on fan ports.

Which are you actually plugged into?

Fan0 1 2 can be used as thermostatically controlled or by the slicer to set speed for part cooling.

The always on ports are... always on.

If you send M106 P1 S0 and the fan won't turn off, then either it's plugged into a different port than you are expecting, or the fan mosfet has been damaged and failed in the on position.

It sounds like you are referring to the "always on" fan outputs - they are not controllable.

Frederick

[CozyP]

I have plugged those two fans on the allways ON ports.
So, after reading your comments, I assume that they cannot be thermostatically controlled???
