The confirm S1 will turn them on correct?
Thank you !

Yes, M106 S is for the speed. 0 is off, 1 is full on. decimal values between act like a percentage. 0.5 is 50%

So the fans are still not on. I plugged them into a separate 12v and also into the 24v print head / extruder fan port and the fans and my temp wiring are working fine. I've switched them on via S1 in the config file as well. Am I missing something else? Is it possible that the connector needs flipped like most of the other had? Odd that the print head / extruder fan works fine and not the nozzle fan... Can I switch that to a different port? Thanks !

It's possible that the mosfet for that fan port has blown. Can you get a good close up photo of the area around the fan ports?
You can see an image of what a damaged mosfet looks like, though they don't always look like this.

Its a brand new board so I hope that's not the case...

The plug is hiding one of them in shadow, so I can't see it. The others I think look ok, but it's a bit blurry. It can work best to get a good focus from a bit farther away and then zooming in a bit.

Where I have it placed I can can't move it that easily and I just got the bed leveled which is a nightmare in and of itself... But that last one looks okay too... It's a fused board so I thought if I had don't anything major it would have either popped the fuse or blew up that fans. Aforementioned the fans are confirmed to be working. I'm going to double check the wiring harness...

The fuse is a lot slower to pop than the mosfets.

That's good. Now for the port.
If you switch one of the other 24v fans to the port and send M106 P1 S1 H-1 command to turn the fan on, where P is the fan number.
Can you post your config.g?
I'm also not sure how wiring the 2 fans in series will affect the PWM control. How exactly do you have the fans wired?
-
@Phaedrux From what I understand and what I've tested wiring the 2 - 12v fans in series to draw 24 v worked and does work for now. I plugged it into the always on port and it worked.
Is there something you can see in my config file Maestro related that I forgot to change or that I need to remove for the Wifi board to function properly? Fan or otherwise?

M106 P1 S1 H-1
Do I insert that into the config file? I just sent the G code ( which gave me a java script error )
If for some reason that port was bad I can run it from fan F0 or F1 correct?
-
@Stephenbright Are you still using firmware 2.03 beta3? Please send M115 and post response. What DWC version are you using? This is shown in DWC in Settings > General in DWC v2 and v3, and in Settings > Software information in DWC v1.
It's quite possible that wiring two 12V fans together has or will cause a problem, and @Phaedrux has been clear it's not advised, and we do not recommend it. If you choose to do it, it's your responsibility.
M106 P1 S1 H-1
That looks like a perfectly valid Gcode to me, and you should be able to run it from the Gcode console in DWC, or send via a serial terminal if connected by USB. Did you type it into the browser address bar by mistake?
As @Phaedrux suggested, test all the fan connections with a 24V fan to check function. First check the fan works on the 'always on' fan connections, then plug it into fan0, fan1 and fan2. You should turn off power when you disconnect or connect a fan, as if the fan pins are turned on, it may damage the MOSFET. With the 24V fan connected to each fan output, send the following gcode to turn each on:
M106 P0 S1 H-1 ; Fan0
M106 P1 S1 H-1 ; Fan1
M106 P2 S1 H-1 ; Fan2Report back what does, or does not, work. Be aware that some two-wire fans don't work with PWM, though should all work with 100% PWM (ie S1).
I don't see any error in your config.g relating to the fans, and the code for Duet 2 Maestro is the same as for Duet 2 Wifi.

Firmware: 2.05.1 (2020-02-09b1)
DWC: 1.22.1
None of the Mosfets look blown. Again it's a new board and I haven't printed anything as soon as I noticed that the nozzle fans were not on. I realize is can blow quick but with the fuses and the lower voltage fan, I would think the fuse or the fan would blow before anything else...
I had the 5v fans installed and I know those were probably blown due to the jumper not set the same as a Maestro from the factory...
No I did not type the gcode in the address bar...
I have 24v fans coming, but I wanted to make sure they were working so I am trying to work with the 2 - 12v fans. I thought they would at least work so I know the board is set up correctly. Long term yes I will use the 24v fans. I can install them and can report back then as I don't want to do any damage...
Until then I had tried to send the gcode you suggested while the fan was plugged into P2 only. I didn't want to try the other ports until I get the 24v fans **
When I type :
M106 P2 S1 H-1 ; Fan2
I get :
PMM106 P1 S0
PMM106 P0 S0
PMM106 S0Then a JAVA error and DWC disconnects?
Thank you !

DWC: 1.22.1
That's a pretty old version of the DWC, and even out of date for DWC v1, so I guess this is a bug in the old version of DWC, as it doesn't do this for me in DWC v1.22.6. On my test rig I have only one fan defined. When I send
M106 P0 S1 H-1 ; Fan0(the '; Fan0' part is just a comment, and can be removed) in DWC v1.22.6, if the fan is already defined (ie fan 0) it turns the fan on. If I sendM106 P2 S1 H-1 ; Fan2when I don't have a fan2 (P2) defined, a new fan is created on the Machine Control page (and turned on to 100%). I'd guess that this is what is not working in the old version of DWC, and causing the Java error. Alternatively, configure all fans in your config.g, so they all show at start up.So try updating to 1.22.6 (the last DWC v1 version) by downloading "DuetWebControl-1.22.6.zip" from https://github.com/Duet3D/RepRapFirmware/releases/tag/2.05.1
Then upload the zip file (don't decompress it) by going to Setting > General > File Upload and click on the big blue 'Upload File(s)' button.Is there any reason your are using DWC v1 rather than the newer version? To update to the latest, download "DuetWebControl-SD-3.1.1.zip" from https://github.com/Duet3D/RepRapFirmware/releases/tag/3.1.1 and follow the same process as above. Both versions of DWC can coexist, so you can switch between them. DWC v3.1.1 has a 'Revert to DWC1' link in 'Machine-Specific > Machine-Specific'. To go from DWC1 to DWC3, remove 'reprap.htm' from the end of the IP address of your printer in the browser's address bar.

I didn't realize when I started to reconfigured my machine that I didn't update the DWC. I'll do that.
Also the 24v fans came in today. With my new 24v fans they are currently 2 separate fans, can I run those in parallel and they would both get 24v correct? Basically two fans into one port, red wire to red wire and black wire to black wire? Thoughts?
** The stock nozzle fans were 2 separate 5v fans in parallel into one port so I would guess they were both getting 5v?
Thoughts?
-
Running the fans in parallel is a bit better than running 2 in series. I've done it on occasion, but it does mean the fans may not behave exactly as they would plugged in solo.
In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each component.
So as long as your two fans aren't huge current draws (most fans aren't) you should be ok.
-
@Phaedrux The new fans are rated Voltage:24V 0.06A each for the two fans. It was a poor design on the part of the printer manufacturer to have the dual 5v fans on one port for such a large printer in the first place... I'll update the process soon. Thanks !

The fan still does not turn on after I tried sending the Gcode...
The new 24v fan is working 100% but not in port 0, 1 or 2. I'm only trying to run one fan at the moment not the two just to make sure I can get this working...
Until now I've never plugged anything in to port 0 or 1, so if I messed up Port 2 in the beginning it would mess up ports 0 and 1 as well?
Aforementioned the first set of fans were only 5v so it would be odd that this board is that sensitive and blown mosfet chip and damage the board vs just blowing up the fan???
Is there an issue with the F500 setting? From the factory is was set at F4, but on the mfg forum, everyone said to set that to F500...
M106 P2 S1 I0 F500 H-1 L0.3
If the mosfets are damaged ( in the picture they look fine ) what are the options? Can I just plug it into a always on port?
Also can I plug the fan directly into the board to make sure the cable isn't the issue correct? I'm going to use a multimeter as well, but I want to make sure the pins aren't coming out when I push the plug in...

Question: The fuse for the FAN section is for all of the fans correct? At this point I'm open to any suggestions.
I can exchange this board for another one, but I want to make sure that if I get a new one that It works and if I made a mistake somewhere that I don't do that again...
Is there any possible way that I need to flip the connectors over? I know it seams odd since the always on fan works but I had to flip all of the motor connectors of due to the build of the Maestro vs the Wifi boards...
As always THANK YOU !
