Three more messages overnight and this morning. They occurred after the printer was cooling down. Looks like another two potential crashes caught and averted. Still no resets to speak of.

*** Memory difference at line 2228 offset 4: original 392e303d copy 00000168, original changed, copy ok, fix=yes
*** Memory difference at line 2228 offset 52: original 20036658 copy 0d0a0d73, original ok, copy changed, fix=no
*** Memory difference at line 2228 offset 4: original 392e303d copy 00000168, original changed, copy ok, fix=yes

Started a long print last night and woke up to two messages in the console:

*** Memory difference at line 2228 offset 4: original 392e303d copy 00000168, original changed, copy ok, fix=yes

*** Memory difference at line 2228 offset 4: original 392e303d copy 00000168, original changed, copy ok, fix=yes

(the same message occurs twice; potential crash caught?) Printer has been stable otherwise.

Two more memory difference messages logged overnight. Printer was idle but has been printing nicely. Still no resets to speak of.

*** Memory difference at line 2228 offset 60: original 2001882c copy 0a0d392e, original ok, copy changed, fix=no

*** Memory difference at line 2228 offset 56: original 2002c5d8 copy 0a0d656e, original ok, copy changed, fix=no

Another memory difference message this afternoon. No resets to speak of, either.

*** Memory difference at line 2228 offset 12: original 0a0d392e copy 20032128, original changed, copy ok, fix=yes

and another

*** Memory difference at line 2228 offset 52: original 20036658 copy 0d0a0d6d, original ok, copy changed, fix=no

edit #3 - busy day...

*** Memory difference at line 2228 offset 60: original 2001882c copy 0a0d392e, original ok, copy changed, fix=no

@Exerqtor With both debug builds I logged a memory difference message within a couple of hours. The first debug build was under an hour, the second took maybe 1-2 hours to show up.

@dc42 Logged a memory difference message with the new build. Printer was idle. No reset as of yet.

*** Memory difference at line 2228 offset 12: original 0d0a0d39 copy 20032958, original changed, copy ok, fix=yes

Logged another memory difference message. Still no reset.

*** Memory difference at line 2228 offset 60: original 2001882c copy 0d0a0d39, original ok, copy changed, fix=no

Had another reset this morning. I didn't record any additional memory difference messages. The printer was sitting idle, cooling down after completing a print about 35-40 minutes prior.

@dc42 Logged another message. Printer was idle at the time, and this was the first memory difference message since my last post. There haven't been any resets since my last post, either.

*** Memory difference at offset 20: was 2001ea80 now 00000000

@dc42 Build installed and running.

and I've logged a message in the console already:

*** Memory difference at offset 24: was a5a5a5a5 now 00000000

That was the final message in the console before the reset. The printer was idle. DWC was open in Chrome.

No reset to report.

I believe that is everything. Let me know if there is any additional information I can provide.

@gloomyandy Ah ok, that actually makes a lot of sense. I'll keep that in mind in the future.

I wanted to add some behavior that I've noticed as I've encountered this issue several times since switching to standalone mode.

A reset just occurred, so here is a more recent M122 (hopefully more of these help!)

The peculiar thing I noticed that while the printer seems to be in working order (config.g loads without error [including toolboard configuration; this is important later], printer homes properly, and bed/tool temperatures look ok along with DHT22/SZP temperatures), the electronics section in the Machine-Specific tab looks like this:

and is missing two toolboard entries; a CannedERCF-SAMMYC21 and a Mellow Fly SHT36 Max V3.

The boards respond to M122.

And if I try to home the V-axis (ERCF Selector axis), the printer hangs in a "Busy" state", the selector axis doesn't move and I have to use the E-stop to reset the printer. After the printer comes back up again, the electronics section is properly populated

and my ERCF configuration executes without issue.

Let me know if I can provide any further information.

I saw a couple of older posts about resets occurring with reason: HardFault imprec, but on 3.5.1, and after encountering the issue myself I added M122 P500 S0 for the more helpful M122 output.

Printer is the same one as here, just running in standalone mode now.

Printer was idle at the time the reset occurred. DWC was open in Chrome 126.0.6478.127 (but I can't be certain on the version with how often Chrome can update). Installed languages were English (United States) and English, for the Chrome UI.

Let me know if there's any other information I can provide.

@Phaedrux It looks like the error was in one of the nested macros I use to lower motor current during homing as after running the blank operations I mentioned above on the files in the /sys folder, the error no longer appears. I guess SBC-mode was acting as an additional filter and caught it which was why I never encountered the errors before.

Thanks for the help!

@Phaedrux Here is a .zip file of the /sys folder. I've been using the 'Blank Operations' in Notepad++ to remove trailing spaces and converting tabs to spaces (along with 'show all characters' on), but nothing has jumped out as an invalid character so far; at least not in homez.g, bed.g, or mesh.g.

While I was troubleshooting this issue, I copied my configuration to an SD card to test if I could reproduce the error in standalone mode following the instructions here.

Upon starting a test print in standalone mode, the DWC console contained several errors while executing start.g that were not present when the same configuration and job gcode was run in SBC mode.

There is also a corresponding error that appears on the PanelDue.

It's difficult to know which commands are giving an error, but from the timestamps the errors seem to coincide with meta gcode commands in homez.g, bed.g, and mesh.g. these errors are unique to standalone mode. I don't get the same behavior in SBC mode.

~oM

First some details about my setup:

• Duet 3 Mini 5+ running 3.5.2 in SBC-mode
• SAMMYC21-powered CannedERCF board running 3.5.2 (acting as CAN-FD passthrough, no configuration pushed)
• Fly-SHT36 Max V3 toolboard running 3.5.2

Last night during a print I had a very strange occurrence; I had a print running with a filament change (M600) inside. The printer ran pause.g without issue(raise Z, move toolhead out of the way, wait for filament change). I changed the filament using the extrusion menu on the PanelDue (retract 100mm at 50mm/sec, then extrude 100mm at 2mm/sec to load). I pressed the resume button on the PanelDue, and the printer didn't respond. I clicked on the Resume button in DWC, and the printer resumed printing.

This was the second time I encountered this specific interaction. However I was unable to extract any debugging information at that time.

This time I was ready.

Here is an M122 captured shortly after resuming the print:

You can see the G1/2/3 commands for the actual print still present in the suspended gcode, and the contents of bed.g present in the buffered gcode along with the notation Doing macro start.g, started by system.

I was up until 3am duplicating my setup to run in standalone mode and I'm currently printing the same gcode to see if the error occurs there, or is exclusive to SBC mode.

Attaching relevant configurations in next post because of character limits.
