duet 2 the wifi only works when plugged into usb

jcwild

my display is a tft and uses 5v and that works but the dwc interface doesnt come up when running from the printers power supply but works and the dwc comes up fine when plugged in

Is this a new board?

Is the 5v LED lit when only the PSU is connected?

Have you tried disconnecting everything else but the PSU input?

Can you share some close up photos of the board?

jcwild

@Phaedrux no not a new board, yes the 5v lights up when powered from psu. no i hooked up everything. also my biqu tft isnt connecting to the board even though it is powered

Phaedrux

It sounds like a regulator has gone. You can provide 5v power via USB if that works for you.

jcwild

@Phaedrux ugh man how tf does stuff like this go bad? i am so sick of these boards. why the hell are they so expensive when they are so fragile like this, i shouldve gone with klipper

Phaedrux

I'm just speculating based on what you've said. Without photos of the board I can't tell if there is an obviously failed component or not.

How old is the board and where did you purchase?

jcwild

@Phaedrux years old at this point and i think i got it from filastruder

@jcwild the WiFi module is powered from the 3.3V rail. Is there any difference in the brightness of the green 3.3V LED depending on whether the USB is connector or not?

Also check that the VIN terminal block screws and power supply connections are tight. You might have a poor VIN ground connection between the Duet and the PSU, and the USB cable might be completing the circuit.

jcwild

@dc42 3.3 led brightness doesnt change from either power source

jcwild

@dc42 is there somewhere i can supply 3.3v rail if its dead? i am using an atx psu so i have it all .

Phaedrux

If it's working when USB is connected you could either use the USB port to provide the 5v, or use the external 5v input connection to supply 5v.

@Phaedrux @dc42 well i now unhooked everything else from the board and tried a different sd card and now wifi just times out even when used plugged into usb

Phaedrux

Do you get any errors?
Can you send M122 and post the results?
Can you share your config.g?

dc42

@jcwild try reinstalling the WiFi firmware. If that doesn't fix it then the WiFi module may need to be replaced.

Phaedrux

M997 S1 to reflash the wifi module.

jcwild

@Phaedrux @dc42 just reflashed the wifi and it does the same, just times out again. here are m122 result and config.gm122 result.txt config.g

@jcwild you are running a very old version of RepRapFirmware. Furthermore, it is a beta version, so it is liable to contains bugs that are fixed in the release version. Please upgrade at least to RepRapFirmware 2.05.1 which you can find at https://github.com/Duet3D/RepRapFirmware/releases/tag/2.05.1.

The beta version of DuetWiFiServer that you are running is much more recent and we have not tested it with such an old version of RepRapFirmware. I suggest you install version 1.23 which you can find via the same link.

Phaedrux

Your config.g file has syntax for RRF3 but the M122 shows it running RRF2. That can't be the config you were using before.

jcwild

@dc42 ok now where can i find the iap4e file? why are all these files so badly spread out and not just pre compiled into an sd card image?

jcwild

@dc42 just updated to exactly what you linked and same deal. timing out
