Duet Maestro random reboot (Hard Fault) during large prints
-
@dc42 That's funny, because that's the second maestro I am using right now...
That's why I can't really believe that a second one has also the same symptoms... -

@dc42 Yes, this is the case

Updated today to the 2.05 release. The print without ethernet from last week went fine, the one from today on 2.05 and over ethernet aborted again.
When you say "over Ethernet", do you mean that you uploaded the file to SD card over Ethernet, and then printed form SD card?
We've seen a very small number of instances of file corruption when uploading large files over Ethernet. So I am wondering whether file corruption could be the issue - although a corrupt file shouldn't cause the firmware to crash, unless the firmware file itself was corrupted when you uploaded it (RRF3 checks for firmware corruption, but RRF2 doesn't). Here are some suggestions:
- Re-run the file that crashed, in simulation mode, without uploading it again, and see whether the simulation completed successfully.
- Use DWC 2.0.4 and enable the feature to do CRC checking when it uploads files.
- Run one of those prints again, and after it has printed several layers, run M122 and post the results here.
You could also consider switching to RepRapFirmware 3.0RC1 in case it either solves the problem or provides more information, although that would require changes to your config.g file.

@dc42 Yes, I upload the gcode and control the printer with the printer connected to the network via ethernet.
If file corruption would be the problem, wouldn't the print also fail during a print of a via ethernet uploaded gcode which was started with the printer being offline over the touchscreen of the printer?I can test your steps this friday. I will report back.

Yes, if you printed the same file from the SD card again, without uploading it again.

@dc42 That's what I did several times and it worked.
