M997 S0 suddenly stopped working

@jml said in M997 S0 suddenly stopped working:
Firmware version 2.01
What is the new firmware you want to flash? If it's RRF3.1 or later, you have to flash RRF3.0 first...
-
I’m on 2.01 because I had edited the firmware slightly back in those days and didn’t ever upgrade to anything newer. What I’m trying to upload is a modified 2.01 (simple custom gcode modification). I have been doing this for weeks on this Duet but it suddenly stopped working. I’ll try the download what was suggested above, thank you.
-
Thank you for the suggestion. I downloaded the new Iap4 file, it did not help unfortunately.
I tried replacing the sys folder with a backed up sys file from November which I know had worked back then, but it also has the same result - M997 S0 just restarts the printer instead of installing new firmware.
The SD appears to work fine - I can launch a print or macro from the screen no issues there.
I have internet problems but can try uploading via DWC when it gets fixed. Is that worth a try, or do you think it might be something else? Should I try doing M997 S0 through USB connection? I have been doing it through the screen.
-
I just tried via USB and mac terminal. Same response. M115 works fine. M997S0 just resets the board and the screen has no message or reaction.
-
can you try 2.5.1 clean install using Bossa, with the SC card contents having the 2.5.1 wifi server etc. If that works then its something weird with your 2.0.1 version.
-
Thanks Tony I'll try that. Will let you know in a day or two, thanks!
-
@T3P3Tony for the 2.5.1 wifi server, do you mean DuetWifiServer1.23.bin? That is the one I see here:
https://github.com/Duet3D/RepRapFirmware/releases/tag/2.05.1I'm using the DuetEthernet by the way, and don't have my internet working currently, so maybe it doesn't matter.
-
@jml If you have a Duet Ethernet the wifi server is irrelevant.
-
I tried a different Duet board and put the same 4 folders (and firmware) onto the SD. M997S0 worked fine (whereas the same 4 folders on the previous Duet didn't work).
On closer inspection I saw that the fan fuse was actually broken. I had replaced that fuse a while ago and the new one must have been damaged when inserting it in with pliers. I don't think that is the issue though because I then shorted the fuse manually with a metal piece and M997 still didn't work.
I don't have the time to troubleshoot the anti-M997 Duet board much, but I'm going to classify it as a hardware/electrical issue that probably happened when there was a fan-related short.
-
Take a close look at the other chips and see if you can spot and scorched. Sounds kind of like a short took something out.
