Reboots/resets randomly - RRF 3.5.0-b4

"Glad" to see i'm not the only one having these crashes, must admit that.

I had another crash mid print roughly an hour ago

Needless to say that the hypothesis of the core issue being a non Duet board was wrong at least.

@Exerqtor this thread is very long so I haven't time to re-read every message although I did search for relevant words, with no hits. So apologies if we have covered this before. However:

'invState' hard faults typically show nonsensical stack data, different every time. We suspect that these faults are caused by transients or ESD. Have you grounded your hot end and extruder metalwork to Duet ground, either directly or through a resistor? This will avoid the act of extruding filament causing static charge to build up, which is likely to flash cover to the thermistor connections.

[Exerqtor]

@dc42 Yeah it's getting pretty long, but starting a new/follow-up thread would potentially "spread" info so I guess keeping everything here still is the best way to go(?).

Uuhm I haven't done so, I'm running a LGX-lite and Revo-micro so there aren't really any obvious places for me to ground either of them.

If you have any ideas of good ways to ground those I'm all ears and will try to deploy it ASAP 😅

If ESD turns out being the issue, it's quite weird that it manifests after FW update though?

[Leonard03]

@Exerqtor here I cand give you an ideea about grounding. After I had almost the same issue about one year ago (?) as David said, I've grounded all seven steppers on by printer by a ring connector (if this is how is called) and three washers between sthe motors and the mounting points. The washers should be the same thickness as the ring of the connector. Not the most elegant way, but it does the job. All connections I've done to the ATX PSU and from there on is groundes by the power plug (seems that the duet2wifi is grounded with the PSU by the negative terminal).

Abount grounding the hotend, I'm running an E3D V6 gold edition with the PT100 and the DB but back then I've contacted E3D but they sayd that the heatsink of the hotend is not conductive, so the only grounding for the filament path is by the motor shaft being in contact with it

[Exerqtor]

@Leonard03 Thanks for weighing in, but i'm pretty sure this is the oposite in my case. Since the extruder stepper ain't in contact with the filament in any way. And the extruder motor aren't in contact with any metal in a regular LGX lite either. Everything on a Revo micro however is conductive

Also, everything is mounted in/on a Voron Stealthburner (printed ABS parts) , no metal conducting anything betwen the extruder and hotend that way either.

[Leonard03]

@Exerqtor that been said.. now I'm thinking about my setup.. I forgot that between the motor and the drive gears for a BMG is the big plastic gear
Seems like I'd grounded only the extruder motor, not the filament path in any way.. Great, another thing to think about

[Exerqtor]

@dc42

I've been looking a little bit into adding ground to the hotend, while I've figgured out a way i may do it I've also voiced the issue on other channels and gotten several concerns regarding it maybe causing a ground loop if it actually is ESD building up.

Some also mentioned (after reading through this post) that ESD don't really look like being the issue since the crashes happen just as often when the printer is idle with no ESD built up, which I didn't even consider when you mentioned it.

But I have to agree ESD buildup from the extruder/motion system being the culprit is debunked when it also happens in idle state.

Don't have anything to add to directly help you (I hope it gets resolved soon!), but if you do make a new thread, I would list all the recommendations that were made to you, and then all the actions you took. Figure that would help cut out the fluff but detail every action that has been taken so far.

Creating a new thread for this issue with RRF 3.5.0-rc1 as subject matter, therefore closing this thread as of 29th october 2023.
