cannot connect to duet 2 Wi-Fi or board

Blunt2007

@droftarts I do have an SD card reader The files that are on the SD card says they want to open with unimaker cure what program do you recommend so I can read the SD card and write g code in it since I cannot connect to the motherboard by a USB and I cannot connect by Wi-Fi what do you recommend I do.

droftarts

@Blunt2007 try setting up the WiFi using runonce.g, before going the erase firmware route.

Use Windows Notepad. The files have .g endings for gcode, but they are just text documents. Just make sure the files you create are 'runonce.g' not 'runonce.g.txt', and that they are plain text files.

@droftarts okay I'm going to use notepad I'll get back to you in a little while probably tomorrow

Blunt2007

@droftarts awesome I got the board to connect to Wi-Fi by using the code you gave me thank you very much for your help much appreciative I got one more question I'm getting notification that it keeps on losing Wi-Fi and has to reconnect to it if I increase bandwidth will that help to keep connected to the board once again I thank you so much I was wrong this board is working now and it connects to Yat. I am getting a green light now and it connects to Wi-Fi

Blunt2007

@droftarts a crud I disconnected from the Wi-Fi unplug the board and then plugged it back in and now it will not connect to Wi-Fi and it will not show a green light in yat. It worked last night but this morning when I connected it it will not connect to the Wi-Fi

Blunt2007

@droftarts when I go into the browser to click on the link that was left there from last night it's coming up with a 404 page not found and in device manager it is showing up on com4 same as last night

@Blunt2007
For YAT:

Try starting Windows in Safe Mode, which should stop any other application from taking over the COM port. See https://support.microsoft.com/en-us/windows/find-safe-mode-and-other-startup-settings-in-windows-10-7551aac3-21b5-c646-06ee-31e0e6a5e4dc
Is the USB cable pushed fully in to the Duet? It may not be making a good connections. Be careful when inserting the cable though, as it is possible to rip the USB port off the Duet, especially if you don't push the cable straight into the port.
If you think the USB port is damaged, take close up picture of the back of the port, where the soldered connections are, and post it here so we can see.
Is the Duet powered only by USB? It can cause problems if you connect the mains power and USB at the same time, and the mains power is poorly earthed. See https://docs.duet3d.com/en/User_manual/Overview/USB_ground_loops

For WiFi:

If the green light next to the WiFi module is on solidly, it has connected to WiFi.
Did you use an IP address, or duettest.local to connect to it?
Does your Duet 2 WiFi have an external aerial, and have you connected it?
For general WiFi troubleshooting, see https://docs.duet3d.com/en/User_manual/Troubleshooting/WiFi_troubleshooting
If you can connect via YAT, send M122 for a system report. The last section shows WiFi details. Copy and paste that into your reply.

Your config.g file will require M552 S1 in it to reconnect to the wifi at startup.

Blunt2007

@Phaedrux I am still at the point of trying to get connected to the board USB is only power going to the board. I pulled the SD card out and put it in my computer and reload it "runonce.g"onto the SD card under config g and it booted up and I was able to connect to Wi-Fi again. I shut it down letting it sit overnight and then I'm going to plug it in again to see if it reestablishes Wi-Fi again I will give you an update tomorrow if it works or or if it doesn't work. If it doesn't work I will reboot the computer in safe mode and try it then

@Blunt2007 said in cannot connect to duet 2 Wi-Fi or board:

It won't automatically connect to wifi unless M552 S1 is present in config.g

droftarts

@Blunt2007 as @Phaedrux said, on the SD card, in the /sys folder, config.g should have M552 S1 in it. If it does, and the WiFi still does not start when the Duet is powered up, copy the config.g file off the SD card on your computer, and post it here.

Because the runonce.g file worked, and you could connect to DWC, I don’t think the problem is with the SD card or SD card socket, but possibly a corrupt config.g is causing problems.

Another thing to try is to remove the SD card, then power the Duet, and try connecting via YAT.

Lastly, if you do connect, either by YAT or WiFi, send M122 and post the result here. In DWC (the WiFi interface) click on ‘Console’ and enter M122 there. See https://docs.duet3d.com/en/User_manual/Reference/Duet_Web_Control_Manual#console for a guide.

@droftarts okay here we go again. I connected the board using USB it connected to Wi-Fi .I unplugged the USB .hooked up my power supply turned on power supply it connected to Wi-Fi and I was able to select different options then it lost signal and would not reconnect I tried shutting off power supply and returned it on and Will not connect Wi-Fi under power supply unplugged power supply .plugged USB back in with power supply off it comes up in device manager and now will not connect Wi-Fi

@droftarts hear the post M122.

@droftarts to get the board working again I had to reload "runonce.g"

droftarts

@Blunt2007 you shouldn’t have to keep on running runonce.g. Your WiFi name and password is stored already. The problem with the WiFi is that it is not being started with config.g. Put the sd card in your computer, copy off the /sys/config.g file, and post it here.

The M122 shows a solid WiFi connection, and that the sd card is working correctly. It doesn’t report on the USB port. You are running older firmware but that’s okay for now.

Ian

Blunt2007

@droftarts do you want the config file now while it's still running or wait until it stops running and then copy the config file

droftarts

@Blunt2007 if you can connect via WiFi, go to the System menu, which should list the files in /sys. Right click on config.g, and select Edit. Then copy and paste the contents to your reply. Extra points if you can put it in code tags </> on the formatting menu, so

It looks like this!

@droftarts I am able to log on to Wi-Fi and it is getting connected now The only thing that is not working is connecting to yat be a USB but it is connecting to Wi-Fi it's been 2 days now and it's still working via Wi-Fi

droftarts

@Blunt2007 That's good to hear. Your config.g looks generally sensible, and has M552 S1 which enables WiFi, in it.

One point: your machine name is 'Ender 5 plus'. Unless you have modified your printer, these machines are cartesian printers, not CoreXY, which you have set with M669 K1. Is that correct?

For the USB, have you tried connecting since the config.g has been updated, and you can reliably connect via WiFi? It may have been continually rebooting before, if there was a configuration problem, which may have caused USB not to connect.

If that still doesn't work, can you post a picture of the back of the USB port, where the pins are? I want to check all the pins are soldered correctly. If they are not, we can exchange it under warranty.
