RRF 3.5.4 - Hardfault bfarValid precise

omtek

I just encountered a 'Hardfault bfarValid precise' reset on my Duet 3 Mini Wifi+ running RRF 3.5.4. The machine was sitting idle at the time, but had run some input shaping movements along with a G29 using the SZP. I had helped with pinpointing the source of this issue in the past, and this is the first Hardfault reset I've encountered since installing the 3.5.3-dbg firmware from dc42 and now 3.5.4.

Another Hardfault. Printer was idle at the time. This one had Expansion spinning.

@omtek thanks for your reports, I will look into them.

@dc42 I meant to update this post sooner to add that I don't know why it started, but it stopped just as mysteriously as it started; including the two reports above, I captured an additional five M122 reports over a 36-ish hour period. The last one was 29 December, and I haven't encountered the issue since. The printer has been on and active with a browser window open to the printer since then.

The two most recent changes made to the printer before the issue occurred was updating the PanelDue 7.0i firmware to 3.5.1 and replacing the toolboard umbilical cable with the newer style molded power-CAN cable from Mellow Fly. I don't know if that had anything to do with it, but I'd be lying if I didn't consider rolling back both those changes when these resets started occurring.

Collected M122s (the two M122 reports above are included in the attached file):
omtek-RRF3.5.4-Duet3Mini5Plus-HardFault-M122.txt

Let me know if I can provide any other information.

@omtek have you changed your browser configuration at all? When I first investigated this issue, whether it occurred or not was related to the size of the HTTP header from the browser, which was affected by the number of languages it was configured to use.

@dc42 I built a new computer in the first week of December '24 and started using Microsoft Edge for DWC; prior to that I was using Google Chrome. I use Google Chrome on my S22U phone to access DWC, as well. This installation of Windows 11 Professional is only a few weeks old and was a fresh installation. I haven't installed any additional languages aside from 'English (United States)' in Windows and Edge just shows two instances of English ('English' and 'English (US)') under preferred languages.
