Duet 2 Wifi Always Disconnects from Wifi and PanelDue



  • This happens after about 2 hrs during a long print. I now have a 20 hr print on my printer, It is about 10hrs in and it will run out of filament before it's done. Since the Duet Wifi is disconnected from the network and the PanelDue 7i what will happen when the filament runs out. Will the filament runout switch pause the printer and if it does how will I be able to resume if both the PanelDue and wifi are disconnected. I belive I am running the latest Duet RRF2.x firmware.

    @Quadcells Connect via USB using YAT. Ensure that you don't have a ground loop; connect with a laptop running on battery ideally, or using a PC that uses the same power outlet as the printer.

    Most likely the print will pause when the filament runout sensor is activated. You could check by triggering the switch. If it does not, send M25 to pause, change filament (before it runs out), then send M24 via USB to resume.

    Is the disconnection happening every print after 2hrs? Really need to see M122 response (ideally from USB, once it disconnects), and config.g to start troubleshooting.

  • And an output of M115 so we can confirm the firmware version



  • @droftarts thanks for the information, I see what happens when I connect my laptop and report back.

    Included in M122 output, except for firmware date.

  • I connected via USB. YAT say's I am connected on com3. I send M115 YAT sends, but does not receive anything.


  • Moderator

    @Quadcells Try a different cable? It would be very odd that the firmware isn't accessibly by USB either.

    Ian



  • try a different cable even if the computer sees the Duet 2 board like it does and say's it is on com port 3?
    I will do it, just seems strange.



  • I have tried 6 cables, it's easy to see what cables work as the one that do Duet 2 shows up in Device Manager and the cables that don't work Duet 2 does not show up in Device Manager. I also tried every baud rate in the pull down list.
    Still M115 does not report anything back after sending.

  • @Quadcells installed the Driver?



  • What driver?



  • @PCR The laptop I am using had those drivers installed. I went and re-installed the drivers and YAT.
    YAT connects to the Duet2 wifi, but sending M115 or M122, still no response from the Duet2 Wifi board.
    I guess I will have to wait to see what happens when the filament runs out.
    Would it help to see my config.g file? I happen to download it before I started the print.

    Can't hurt. Does seem that all communication has ceased. I'd guess some buffer overflow, that hasn't effected the motion planner. I'd still expect pause to work, but then you're going to have problems restarting it. I'd feed in filament behind the old filament so it doesn't pause, to finish the print, rather than risk it pausing but failing to restart. If you have M911 (power loss) defined, you could just pull the plug!

    Ian



  • It will be tough to push filament thru the way my setup is, but I can try. This really sucks if I lose this print.
    I never set up M911 since I have my printer on a large UPS. But I will now if it helps in this type of problem. I also have debug off (M111 S0).
    BTW: this communication lose happens on both of my Duet2 Wifi boards. After this I really need to find out why this happens. Maybe I should think about moving to RRF3.x but was skeptical since one printer is a delta, the other a core xy with a Bltouch which I heard could be problems with RRF3.x but that might of been in earlier release of the firmware.

  • Update:
    I decided to send M552 S1 to the printer via YAT and then the printer showed up on my wireless network.
    But still cannot access the Duet using DWC.
    I sent M552 S0 and the blue LED next to the wifi module turned off.
    I sent M552 S1 and the LED flashed and then stayed on.
    Still cannot access the Duet board.


  • Moderator

    @Quadcells Try M552 S-1 (disables Wifi module), then M552 S1. But I think it's unlikely to work, as it seems like all comms are not working. It would be really good to get an M122 report as soon as you can!

    Ian



  • Hi, Well I could not feed the filament through and it paused and no way to resume.
    Funny how "STOP" worked on the paneldue and nothing else. As soon as I hit Stop connection to YAT started to work.

    Thanks. Since you're running a Duex I have to ask if it's wired to spec as lockups like this can happen when the ground cable isn't wired as shown here: https://duet3d.dozuki.com/Wiki/Duex2_and_Duex5_Features#Section_Wiring



  • @Phaedrux is this wrong?

  • @Phaedrux no, mine has the wires from the power supply going to the Duex5 then to the Duet wifi.


  • Moderator

    @Quadcells Wasn't there another thread about your power/GND wiring? I think we ended up thinking it was okay.

    Ian



  • @droftarts that wasn't me, but if the gnd resistance from the Duet to the duex5 then what I have should be fine especially the same thing happens to my delta which only has a Duet.
