Tool/Part fan confusion

Chriss

Hi *,

I have a problem with my fans, again. This is at least the 3rd time I have problems with that and I want to get rid of that confusion now, I hope that you guys can help me.

I think that I have a problem with the mapping of the fan. The reason for that is easy: I tried to lower the speed of the part cooling fan during a print and in the webUI and I saw that the factor of the hotend reduced at the same moment. Does that make sense? I have the understanding that I should be able to change both of them individually, don't I?
Funny is that the hotend fan is reported at the hotend as off (0%) in the webUi while the print is printing the first layer and the fan is spinning.

The fan "Tool Fan" is spinning and the "Tool Fan" is off.

The other slider is moving when I move the other:

It makes no difference whether I change "Tool Fan" or "Part". :?

The concept seams to work, so the "Tool Fan" starts at the right temperature of the tool and the "Part" fan starts at layer 3 or 4, whatever I have configured in the slicer.

Board: Duet 3 MB6HC (MB6HC)
DSF Version: 3.1.1
Firmware: RepRapFirmware for Duet 3 MB6HC 3.1.1 (2020-05-19b2)

The part from the config.g

;; Fans
; Fan for the printed part:
M950 F0 C"0.out9" Q500                       ; create fan 0 on pin 0.out9 and set its frequency
M106 P0 S0 H-1 C"Part"                       ; set fan 0 value. Thermostatic control is turned off
; Fan for the Hotend:
M950 F1 C"0.out8" Q500                       ; create fan 1 on pin 0.out9 and set its frequency
M106 P1 S1 H1 T45 C"Hotend"                  ; P="set fan 1" S="value" H="Thermostatic control Heater No." T=" is turned on at 45°C"


;; Tools
; Tool 0
M563 P0 S"TooL0" D0 H1 F0		             ; define tool 0
G10 P0 X0 Y0 Z0                              ; set tool 0 axis offsets
G10 P0 R0 S0                                 ; set initial tool 0 active and standby temperatures to 0C

I'm a bit confused about the name of the fan "F1" anyway, I named it "Hotend" with the last M106, didn't I?

What do I do wrong here? What did I misunderstood?

Cheers, Chriss

The tool fan slider is a special slider in DWC. It's not a particular fan, it's whatever fan is active right now based on which tool is selected. So in your case with one tool the part fan and the tool fan are one and the same. You can hide the tool fan from being displayed if you like. Click on Change Visibility.

Which fans do you have plugged into which ports on the board itself?

Ah, I see, the gui fooled me a bit. That explains why I'm not able to rename it. I think that my confusion came from there.

Which fans do you have plugged into which ports on the board itself?

The fans are connected as it is it the config:
0,out8 cools the hotend
0.out9 cools the printed part.

I checked that a minute ago by pulling wires.
