Duet2 wifi stuck repeating Wifi Error.

zBeeble

OK. Plugged in the console. Used cu to talk to it by default. It doesn't seem to send CR's (only LF) so I assume one needs something more like a traditional term program. Also, I found that typing halted the current print and that USB power kept the board on (I use the power switch as the ultimate oops --- oh NOOOO ... button.

help?

gloomyandy

@zBeeble What did you type? Normally commands via USB will not impact printing. USB power will keep the board on, but it will not power the stepper motors so turning off the main power should still stop the printer.

zBeeble

@zBeeble I was trying to type m112, but it seemed to glitch at typing the 'm' ... now I was set for 57600 (since I didn't know what to choose)...?

gloomyandy

@zBeeble If you typed M112 then that is "emergency stop" (see: https://docs.duet3d.com/User_manual/Reference/Gcodes#m112-emergency-stop), so your printer did what you told it to do!

I'd guess you wanted M122 not M112. If you are using a direct USB connection between your computer and the board then the baud rate is in effect ignored.

@zBeeble see our recommendations for serial terminals here: https://docs.duet3d.com/en/How_to_guides/Getting_connected/Getting_connected_to_your_Duet#h-3-connect-to-duet

I did notice it showed up as umodem rather than one of the userials I'm used to:

umodem0 on uhub3
umodem0: <Duet3D Duet, class 2/0, rev 2.00/1.00, addr 2> on usbus3
umodem0: data interface 1, has CM over data, has no break```

@zBeeble The instructions for updating WiFi firmware only is at: https://docs.duet3d.com/User_manual/RepRapFirmware/Updating_firmware#updating-wifi-firmware

You might want to clarify there a bit. There's nothing wrong with that recomendation, but you should go a step further. For instance, minicom does everything required and runs in a terminal. tmux or screen can manage long running terminals when the other computer might reboot or suffer some other calamity (like being a laptop).

If you add minicom, you might note that from stock config, turning on 'add carriage return' and turning on 'line wrap' and turning on 'local echo' are really good settings.

zBeeble

OK. The crazy that needed to finish is done. The new wifi binary is loaded and I have a minicom terminal in a tmux that should live just fine when the laptop leaves for the nation's capital at the end of the week.

I think a short hiccup with the wifi occurred. I see some disconnects in the log... but this was before the log-log.

I'm kinda relying on you guys that this setup is correct for logging. I see a print stopping, but not starting on the console and I don't see, say, if I run m111 on the web console. I do see a result to running an m command (like m111) on the serial console, tho... so... fingers crossed.

zBeeble

Hey... is it supposed to say this:

m111

zBeeble

The bottom bit of m122 is as follows (and it's a bit of pain that this code changes in my head to 112)

WiFi is module 14, Network is module 1 (at least for me on a Duet 3 Mini 5+) so send M111 P14 S1 and M111 P1 S1 at startup to enable logging of those, with your serial terminal connected.

We do! See https://docs.duet3d.com/en/How_to_guides/Getting_connected/Getting_connected_to_your_Duet#minicom

Press CTRL-A then W for linewrap, CTRL-A then U for CR at end of line, and CTRL-A then E for local echo. CTRL-A then X quits Minicom, releasing the port.

OK. That works, but I don't see leaving network on --- it's chatty even when the printer is not doing anything. That's just a disk filling service.

So... I'm preparing to leave for BSDCan. Printer has been idle for about 24h. I was in the area and saw this:

https://nextcloud.towernet.ca/s/FNtRo4MyJHiG7PR

So then I checked the console...

followed by...

WiFi: I (190597586) wifi:bcn_timout,ap_probe_send_start

Now... this wasn't a repeating error, but I'm reporting it anyways.

rechrtb

@zBeeble Seems like the disconnect was detected at the lower levels of the ESP WiFi stack. The upper layers did what it's supposed to and attempted a reconnect. I don't think this was what causes the repeated SPI timeout error - but noted nontheless.

zBeeble

Would you guys expected this debug wifi to be significantly slower?

rechrtb

@zBeeble You mean in terms of like upload/download speed? Debug builds would be 'unoptimized' so yes.
Also, by the way, did the repeated "SPI timeout" issue not appear till now?

I didn't notice it until now, but I can't answer with certainty.

zBeeble

OK. So ... printers been idle for a week or two --- serial console connected to system that stays online. Nothing to note.

However, was just printing something and the web UI had a few seconds where it was complaining no connection. This is certainly something I noticed before the larger problems.

No activity on the serial console, tho. Should I be entering something to turn that up?

rechrtb

@zBeeble Nothing beyond turning on the debug messages for network and WiFi. If I'm correct, you turned off the network debug messages though since it was too noisy? Also, please make sure it's logging to file so we don't miss anything.

Yeah... the networking was generating a line every so often ... printer on or not.

But the machine is connected to the home server ... which is always on. I'm using minicom ... which is set to log all traffic
