The only thing I notice is that now I see two fans in the DWC and they do the same thing.

That's normal. It makes more sense if you have multiple tools. The tool fan is the fan of the currently selected tool. The other fan is the fan itself. If you don't want to see both, hide one with the Change Visibility button.

Ok thank you again, I had it hidden and your explanation makes sense. This is my first experience with the Duet and so far I am really enjoying it, I can't wait to add it to my other printers as well.

@crazycraig Your config.g has 2 tool definitions in it, so your changes are being over ridden later on in the file.

; Part cooling fan
M950 F0 C"e1heat" Q100; Fan 0 is connected to heater 1 pin, PWM at 100Hz   
M106 P0 C"Air Pump" S0 H-1
M563 P0 D0 H1 F0

And later on below

M950 F2 C"fan2" Q500                               ; create fan 2 on pin fan2 and set its frequency
M106 P2 S1 H1 T50                                  ; set fan 2 value. Thermostatic control is turned on

; Tools
M563 P0 D0 H1 F2                                   ; define tool 0

So move the first M563 down to replace the bottom M563.

Thank you so much, I can't believe I didn't see that. The pump now turns on when the g-code tells it to.

The only thing I notice is that now I see two fans in the DWC and they do the same thing. Did I mess something else up in the config?

config.g

Attached is my config file. I am a newbie when it comes to the duet, so please be gentle. The issue has to be in my config, I tested with Cura and I get the same results. I did notice that if I just issue an M106 S255 with no jobs running the air pump turns on, but If I do the same thing while a print is running, it modifies the hotend fan.

Thank you

@dc42 Yes I have read that, but I wanted to control my air pump for part cooling without needing additional components. This is why I am using the second extruder output. I followed others who have done the same, but I am wondering if my slicer is not playing nice with these changes.

@deckingman This is the gcode where S3D is supposed to turn on the fan

; layer 10, Z = 7.463
M106 S255
G4 P500
M106 S191

If I run the M106 command in the console my air pump works.

I am going to look into setting a cura profile and see what that does.

@Phaedrux Sorry I meant I can control the hotend fan while there is a print running. When the gcode is sent to supposedly turn on the airpump/part cooling fan, it actually adjusts the hotend fan.

I have my air pump connected to the extruder1 output and the heatbreak fan connected to F2. I know that typically F0 is the part cooling fan and F1 is the heatbreak. I can control the fans fine in the web gui. Do I need to change something for S3D to activate the pump when I set the part cooling fan on?

Hello, I have search for this but I am not finding much help. I have an air pump connected to E1 and I can turn it on via DWC. But simplify3d is not activating it. It does however adjust my heatbreak fan for some reason, I mapped that one to F2.

Here are my specs
Board: Duet 2 WiFi (2WiFi)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.1.1 (2020-05-19b2)
Duet WiFi Server Version: 1.23

My config file for fans

; Part cooling fan
M950 F0 C"e1heat" Q100; Fan 0 is connected to heater 1 pin, PWM at 100Hz
M106 P0 I0 C"Air Pump" S0 H-1
M563 P0 D0 H1 F0

; Fans
;M950 F0 C"fan0" Q500 ; create fan 0 on pin fan0 and set its frequency
;M106 P0 S1 H-1 ; set fan 0 value. Thermostatic control is turned off
;M950 F1 C"fan1" Q500 ; create fan 1 on pin fan1 and set its frequency
;M106 P1 S1 H-1 ; set fan 1 value. Thermostatic control is turned off
M950 F2 C"fan2" Q500 ; create fan 2 on pin fan2 and set its frequency
M106 P2 S1 H1 T50 ; set fan 2 value. Thermostatic control is turned on

I have to clean up my code and remove those commented out fans.

Here is the line in my gcode that is supposed to start the part cooling fan

; layer 10, Z = 7.463
M106 S255
G4 P500
M106 S191

I am sorry if this has been asked or is in the wrong catergory, but I have tried to do what I can from the search results I found so far.

Thank you for any help
