      @sphyloid, 0u1 typically means 0.1uf = 100nf.

      @jbjbjb82 said in Duet 2 Wifi Fans setup:

      Can I connect the positive to the 5V pin of the Jumper Select and negative to the GND pin of the FAN1 connector? If so, will this allow to use thermostatic control, so that this 5V fan start running at 45ºC?

      Yes. The Duet switches PWM on the negative side, so as long as the negative wire of the fan is connected to Fan1 you will be able to control it regardless of where it gets it's voltage source from.

      When using multiple fan voltages in the same system be very careful not to short out a higher voltage into the 5v side.

      @sphyloid google docs imports those CSVs ok if you want a "free" alternative that's more than a text editor.

      They should stay in sync fairly well I think, but after a while you may notice some drift.

      I found cheap connectors on ebay and ordered them. This topic is solved but will stay around as a testament to my stupidity (-:

      @dc42 glad to hear the next revision of the toolboard will have different connectors which are a bit easier to get hold of (and crimp). Luckily, I don't immediately need the second thermistor input right now (although I plan to use it to test heatsink/hotend performance in the future).

      @dougal1957 said in Convert Duet Ethernet to WIFI:

      Why not add the Pi now and use its wifi to Ethernet bridge and you will be ready for the SBC whenever you want?

      To be honest @Dougal1957 I don't follow the technical side of the forum much, and I don't really know what the benefits of using an SBC are.

      At the moment I'm just trying to get the polar printer to a point that I'm happy to start reliability banging out parts.

      It works now and I'm into updates re the practicalities of running and maintaining it.

      A 12864 display for stand alone ops so I don't need my pc. A filament monitor to reduce failed prints as my prints are multiple days long. A pendant, primarily for ease of maintenance. WiFi as the ethernet cable is starting to piss me off but less necessary now I have the 12864 display. TBH I could just use a WiFi to ethernet bridge and might do that just to get on.

      After a couple of months of running I'll look into building a second printer using the learning from the first.

      The VIN reading returned normal after replacing the R80. Thanks.

      Was this a genuine Duet, or a clone?

      When you test your duel z motors. If it runs the wrong way chainge direction in the G code ,, i assume you have two motors and yes its possable to have one running the opposite of the other z motor (incorect wiring) in that case you must rewire so both turn the same direction it does matter that both motors on your z run the same direction. So "when" they do and if they turn the the wrong direction chainge it in your your gcode. go to system tab on the dwc user interface open your config .g file.
      Under drives youl see (M-569. P0 S0.) By changing
      S0 to S1 will chaing the direction of all your stepper. As far as XYZ and X is concerned.. its the same for all. Also for double Z motors. Both z motors should turn same directoin if they dont cainge one motors wiring then correct rotation on your config .g file hopefully this helps 🙂

      @nmsmith89 said in Questions about Duet 3 Mini 5+ wiring.:

      I was under the impression that the Mini couldn't power the RPi like the 6HC could. Only the other way around.

      😩 My mistake!

      @nmsmith89 said in Questions about Duet 3 Mini 5+ wiring.:

      Are there any problems/concerns with powering the Duet and the RPi from a 5V PSU? Is that overkill? Although with the addition of a bunch of Neopixels it might be necessary.

      Nothing wrong with that at all. In fact it allows you to use a relay to control the main PSU on and off.

      @cncmodeller I'm using a seperate Arduino to drive the backlight. Works fine.

      I have some ATMega44 chips soldered on a small SOP16 PCB(*), would they be powerful enough to drive the Neopixel?
      Can you compile your program with Atmega44 selected?
      Does it switch the backlight on/off, when I push the button on the LCD?

      Yes, and if not, try using a cotton swab with isopropyl and gently clean the area. Careful with the resistor there.

      That message is coming from a user macro and not the firmware. What did you push before you got that message?

      Hardware seems functional. For further help you'll have to provide some config files. config.g, homeall.g, homex homey homez bed.g and results of M98 P"config.g".

      @cncmodeller said in Two arduinos between Duet2 wifi and BLtouch:

      Hi @dc42, what is the timeline on the external driver version of the Duet 3 main board? Are there details available?

      My guess is 3 months. However, there is a severe shortage of semiconductors developing, so we may have to change our design plans to suit what is available rather than what we would like to use.

      Ok thanks for the info, I'll keep a weather eye in the forum for future updates. 🙂

      Just to mention:
      PanelDue uses resistive touchscreen not capacitive one - so putting any glass lens in front of it will make touch unusable.

      @steppenleguan the fan fuse (F2) is for V_in I think the board can have a Problem you can try to measure ohmic if you have a connection between the 5V Fan connector to a other point which has 5V(switch off the board before). Here you can get the schematic from The board [https://github.com/Duet3D/Duet-2-Hardware/blob/master/Duet2/Duet2v1.04/Duet2_1.04b_Schematic.pdf](Duet schematic) on page six you can see the Power selector for V-Fan

      I was testing out the remaining unmapped features/parts of my Klipper conversion for the Duet3 mini, and wanted to see if I could hook up a reprap display i had laying around vs the 12864 that's explicitly allowed in the docs.

      Learning exercise for me, I appreciate the input.

      Photos of the board may show a blown component. Depending on how extensive the damage was it may be recoverable by a firmware flash...

      Which LED specifically is lit when connected to power? What's it labeled as?

      @droftarts I fixed the channel assignments and disconnected heater 1. System still went into reset and looked like a short because all the PCB LEDs blank out the moment I select either T0 or H1 (GUI links), or send T0 by the console.

      However, the heaters are working now and I've tuned them up already.
      I tried a few more times with T0 or T1 though and haven't been able to force a reset. It would be great if it stayed this way!

      thanks
