DUET 3 can't connect over ethernet anymore

dsela · 20 Feb 2023, 11:34

Hi,
I'm having issues connecting to DUET 3 over ethernet. Everything was working OK for a while, I made a lot of changes to the config files and one time after resetting I just couldn't connect anymore.
I tried connecting via USB and YAT to check the ethernet - I sent M552 S1 and got that everything is OK, configured IP address 192.168.2.3 actual IP address 0.0.0.0 (not sure if this is OK)..
Tried resetting the network and nothing worked..I took the SD card and changed the config.g to what it was before I resetted the board this time, and now it connected.
I thought I solved it but today I turned on the machine again and it didn't connect. Check via USB and YAT - same as before. Tried changing the config.g file again (though I didn't make changes since it worked last time) - didn't help..
Please assist

Thanks

@dsela The response from the firmware indicates that there is no connection; you are manually setting the IP address (looking at your config.g from your other thread), but the 'actual' IP address is 0.0.0.0. Especially as it is intermittent, check the ethernet cable you are using, and the physical ethernet port on the Duet and router for damage or poor cable connection. Do you see lights on the Ethernet port?

@droftarts I tried to manually set the IP address to a different one though YAT - this time it worked and I could get connected.
It seems like either config.g is not loading correctly or there's something wrong with the IP address i'm trying to set (though it worked fine for months)

I didn't mention - I'm on a direct connection between the computer and the DUET, no router in-between (though the computer is connected to Wifi).

Regarding lights on the ethernet port - you mean on the DUET? should they light up even when the cable is disconnected? Because it's very hard to see them with the cable connected.

@droftarts I think I found something..I noticed that when I connect via YAT I get a lot of temperature readings (since I have a tool with 4 temperature sensors and one of the changes I made was that it will load up with temperature 215 and not 0).
When I sent M552 S1 P192.168.2.3 I usually didn't get the response that it was set after 30 seconds..instead I kept seeing these temperature readings.
When I reverted the tool temperature back to 0, the problem seemed to be resolved..any ideas how to set the temperature and not have connectivity issues?

@dsela Can you post your full config.g, M115 response, and response to M98 P"config.g"?

You say you are setting the target temperature in config.g, so the heater is warming up straight away? It's possible that the Gcode you are using is waiting for the temperature to be reached, and blocking any DWC interaction until that happens. That may be why you get temperature readings and nothing else. For safety, it is not advisable to set a temperature in config.g for immediate heating, because if an emergency stop has been needed, it will start heating again as soon as the mainboard resets.

@droftarts Got it, I'll leave the heating off for starting..btw the M98 response is in the other thread, if you'd still like to see it.

Thanks

@dsela said in DUET 3 can't connect over ethernet anymore:

btw the M98 response is in the other thread, if you'd still like to see it.

For timely support, it is best to post all relevant info in the thread where you ask the question, even if it means repetition, rather than expecting people helping you to hunt through other threads.
