DWC not accessible, M122 causes timeout

chrishamm

@stretchy What is the IP address of your computer's Ethernet adapter? It is rather unusual to have a link-local IP address (169.254..) in config.g, so I suspect you connect your board directly to your PC. If the Duet is connected to your router and not directly to your PC, change M552 P169.254.183.38 S1 to M552 P0.0.0.0 S1 and remove the line starting with M554 P169.254.183.0.

@chrishamm oops, I failed to mention that It is indeed connected directly to my PC. Tried on two PCs with a USB Ethernet Adapter and their built-in Ethernet ports. Pinging always works. In the network configuration the network shows up as 169.254.183.40 instead of the set ...38.

I tried updating the firmware using the first fallback method mentioned here:
https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware_(Legacy)#Section_Fallback_procedure_Num_1
It didn't work but fallback #2 did by commenting out M552 in config.g.
Now im on 2.05.1, DWC still isn't working but the controller no longer crashes on M552 Pn.n.n.n S1 commands.

Are you able to connect the Duet to a router and use DHCP as a test?

Do you have a different computer/browser to test with as well?

The Duet appears to be responding as it should, the DWC is just not loading on the PC. There could be external network reasons for that as well.

The ethernet port lights are showing activity. The SD card is being read and showing the DWC files there. It's responding to pings. It responds over USB terminal and took a firmware update.

Which reminds me, when you updated the firmware to 2.05.1 did you also update the DWC files in the /www folder?

I've revisited my duet2 ethernet machine and the error still persists. Things that changed since last time are:
-updated to RRF3.0 and DWC 3.x
-m122 works now as long as networking is disabled (m552 s0)

Below is an orderly list demonstrating what my problem looks like. I want to know if there is a possible mismatch of Firmware/DWC or some low level firmware is bricked. Basically is this fixable or will I need a new board and could I potentially get away with a new ethernet daughter board?

@stretchy said in DWC not accessible, M122 causes timeout:

this obviously sticks out but i dont know what to make of it nor how to fix it.
Any help is greatly appreciated. Apologies for the multiple posts but akismet.com would not allow a post that long and sections of the M122 response.

this shows you're setting the gateway on the duet to the same IP address as you're setting the win10 IP address. Is that correct?
Can you set the Win10 IP address to a different IP?

This is a direct ethernet connection between the duet and win10 pc?

Phaedrux

When and where did you purchase the Duet?

stretchy

@phaedrux yes the Duet2 Ethernet board is directly connected to a dedicated PC for that single machine.

stretchy

@phaedrux the duet 2 board was purchased on duet3d.com, I believe in mid 2020 to early 2021.

chrishamm

@stretchy RepRapFirmware 3.0 is outdated, please upgrade to RRF+DWC v3.3 or newer - see here. If the board still fails to serve the web interface after that, please try to access it from another device (e.g. smartphone or tablet) and check if that works. If it still resets at some point, please share the output from M122 again.

stretchy

@chrishamm I've updated to RRF3.3 using these steps:

copy Duet2CombinedFirmware.bin to /sys
copy the folders /js, /css, /fonts, /img into /sys (not documented what they do but to be safe I copied these too)
copy the Duet2CombinedIAP.bin to the SD card (can only be found in the old RRF 3.0 release, iap4e.bin does not work anymore)
insert SD and M997 S0 to start update
M115 to verify update
M122 to gather new log

@stretchy
the issue still persists; DWC is not accessible through a browser while pinging the IP is possible.
M122 works but only before I enable networking (M552 S1), after I've done so M122 crashes the board, it's rebooted ~15s later and the config.g is loaded again with networking disabled. Therefore M122 works again.

Phaedrux

@stretchy said in DWC not accessible, M122 causes timeout:

copy the folders /js, /css, /fonts, /img into /sys (not documented what they do but to be safe I copied these too)

These must be in the /www folder. Do you also have them there?
Can you show a screen shot of your folder structure?

chrishamm

@stretchy Thanks for that! Any ideas @dc42?

dc42

@stretchy if sending M552 S1 followed by sending M122 causes timeout, then it sounds to me that the Ethernet module has failed. Is the chip on it getting hot?

If the board was less than one year old from when you purchased it to when you first reported this problem, then we will replace the board under warranty. If not, then the Ethernet module is available separately, and a new one may fix the problem.
